Rodent Management Services

No one likes seeing a rat or a mouse in a commercial establishment, whether it’s in a restaurant, office or workshop – rodents are bad for business.

If there was any pest that is associated with disease, dirtiness and just being plain gross it would be rodents.

Rats and mice have a knack for spreading discomfort to anyone who lays eyes on them and in this day and age a negative online review can go a long way in hurting future business.

If you’ve heard or seen any of these disease carrying vermin in your workplace, then it’s time to call in a professional and get those pests gone before they chase away customers!

Both rats and mice are notorious pests, known for breeding quickly and being responsible for spreading many dangerous diseases.

When left untreated they can quickly develop into a very serious infestation which makes rodent management much, much harder.

The main areas that these vermin are drawn to are the kitchen, living areas, and garbage collection areas where they can cause a wealth of problems for any Sydney resident or business owner.

Protecta Shield & Low Profile (LP) Sidekick Tamper Resistant Rodent Bait Stations

Instructions to unlock with the Protecta bait station key:

  1. Push the key straight down and lever it as far as possible. Try and lever it up using your fingers or thumb.
  2. Pull right back on the key away from the box station while at the same time pulling up the lid
  3. When it opens, lift the lid completely upwards as far as it will go using the key.
  4. Repeat again on the 2nd lock to open it right up

Inserting the Bait Rods:

  1. Insert either end of the metal Bait Rod into the circular hole in the base of the baiting areas (x4)
  2. Place the bait onto the installed Bait Rod – this can be stacked toward the top of the rod.
  3. Close the lid of the Protecta Bait station securely – it will make a “click” sound when secured.


NB: The locking mechanism on the bait station may be a little stiff upon the first opening. It gets much more flexible after a few openings.

  • Rats and mice are known for causing substantial physical damage to a property.
  • They need to continuously gnaw on hard materials in order to keep their teeth at an appropriate length. This habitual gnawing can result in damage to structural components such as walls, door-frames, skirting boards and more.
  • Other materials that can be damaged by gnawing include wires and cables, upholstery and similar materials, books, and even food containers. The result can be a building that is structurally unsound—or where fire risks are substantially increased.
  • Rats and mice not only cause damage to a property, but they leave plenty of evidence of it, too. Droppings, urine stains, unpleasant odours, and smear-marks are common in properties plagued by rodents. These have a negative effect on the overall ambiance of a property.
  • They have a reputation for spreading disease, and it’s one that’s well-deserved.
  • Rodents are responsible for spreading more than 35 types of serious diseases worldwide.
  • These diseases can be transmitted via several different means. Urine and faeces may contaminate food, for example, and indirect contamination may occur from interactions with pets or insects infected by a rodent-carried disease.

Setting up the Bait Station

These bait stations can be set up indoors or outdoors and should ideally be placed in any high traffic area where rodents are often sighted. These can also be affixed to a floor or wall using a screw or nail through the hole on the base of the bait station, this can only be accessed when the station is unlocked which prevents anyone from tampering with the bait station.

Pictures for reference

Our technicians will always tell you exactly where the baits are located and will photograph them for your reference if needed.

We’ve serviced hundreds of properties to help manage rodent problems and can confidently say that it is essential for any business owner to have a reliable rodent control system in place – whether this is in the form of frequent treatments or a baiting system in itself. In the worst case scenario restaurants and businesses can be shut down and deemed “un-liveable” if the problem is severe resulting not into in the cost of reparations but financial loss due to being closed down!

One of the newer baiting stations has the semblance of a rock and as such it is unobtrusive and doesn’t advertise the fact that there might be rodents on a property! These baits can also be bolted, screwed, or glued down. They come with a handy service log sticker and require a unique key to open – great for any properties that have children or pets that might disturb the rodent baits. Contact us if you’d like to discuss further treatment options.

Most traps or pellets are great at killing off a few rodents but to get rid of an infestation or proof a property against infestation you need to get a property rodent management system in place. A1 Pest Control has over 3 DECADES of experience in successfully controlling rodent infestations and making sure that they don’t come back! Call us today on 0417 251 911 for a competitive quote or to book us in and get rid of those vermin!

When you move into a house or commercial premises it can be a tad unpleasant to find that rodents have moved in with you! However with good hygiene, prevention, and rodent control methods, it is possible to eliminate these pests from your property, whether you choose to deal with it yourself or call in professional pest exterminators.

Different types of house rodent

It’s important to determine the type of rodent you have in your home or business so that you can implement the best treatment program, such as setting the right type of traps.

  • Mice – these creatures are very small, being only up to 20cm in length and 30g in weight, with long whiskers, a long tail, and large floppy ears. They can be white, grey or brown in colour.
  • Rats – The most common house rats are the black or roof rat and the brown or Norway rat. Rats are larger than mice being up to 40cm in length. They are also more cautious in their behaviour than mice.

Both rats and mice are nocturnal and they show some similar behaviours – including fast breeding, munching on your wooden beams or furniture, leaving droppings behind, and spreading infections!

Setting traps 

Naturally rat traps are going to be bigger than mouse traps. For rat trap baits try using nuts, dried fruit, peanut butter or small pieces of bacon. For mouse traps use small pieces of chocolate, or nuts, peanut butter or grains such as oats.

Set traps along the walls or other paths where the rodents run between food sources and the nest. Rats are generally more wary of change so you could try leaving the unset traps in place for some time so they adapt to them.

Rodent toxic baits

Poisonous baits work by causing internal bleeding, or through the rodent ingesting a toxic substance, and are slower to act than traps. Baits should be handled with a lot of care and should not be touched with bare hands, or be left in areas where small children or pets can come across them. This is especially important where you have curious babies or toddlers in the house, who love to put everything in their mouths!

Need Professional Help? 

You might want to consider getting a professional inspection done of your property to determine the level of infestation and the best method of eradication. A high-quality pest controller should also be able to advise you regarding prevention of future infestations.

Getting Rid of Rats
Article Author: Bruce Gow

 “We know how much of a persistent pest rats can be and therefor we take extra measures to make sure they are disposed of and not tempted to return to your premises!”

 Got a rat problem? Rats are more than just annoying. They’re dangerous disease spreading rodents that can also cause a great deal of damage to property. They may even be responsible for starting some house fires – particularly in older homes – by gnawing through electrical cables.



Once you have a colony of rats in close proximity it can be difficult to get rid of them. Rats are nocturnal, so there’s almost no chance you’ll spot them during the day time. Rats are also shy and wary creatures with great survival instincts. They’re said to be ‘neophobic’ which means that they don’t like new things – making it difficult to quickly tempt them into a trap, or get them to immediately take to rat bait.

Fact sheet on Brown Rats

If those factors didn’t make it difficult enough, rats eventually develop immunity to products that are used to bait and lure them. Products that were successful in the 1940s are no longer of much use. New products developed in the 1970s have proved relatively successful to-date however it appears that rats are beginning to develop a resistance to those too.

So how do you get rid of rats? Eradicating rats requires a multi-pronged approach.  You’re likely to need the help of a qualified pest controller to locate the rats nest, establish how the rats are entering the area, and to lay baits safely and in the right places.

Click here for facts on Black Rat

There are things you’ll need to do too. Rats look for a home that offers them good shelter, a discreet entrance and exit, and a source of food that’s not far from home. Removing potential sources of food (like dry pet food or other stored food items that aren’t properly sealed), and blocking potential entrances (broken roof tiles, gaps under doors and the like) can make your place a lot less inviting.
 The importance of managing neophobia (the fear of new things)

 In Australia we tend not to hear a great deal about the health risks associated with rodent infestations. This is quite a contrast to the headlines often seen in Europe and the US. However, various zoonotic diseases in Australia rodent pests are quite well documented.

In recent years Steptobacillus moniliformis, Angiostrongylus cantonesis, lymphocytic choriomeningitis virus, leptospirosis, rickettsia and cryptosporidia have all been documented as causes for concern. Fortunately, whilst hantavirus antibody-positive rodents have been found across Australia, it has not yet been reported in humans.

A core issue in managing rodent problems quickly is the natural neophobia (fear of new things) displayed by rodents, the strong suspicion of and awareness to change and the presence of unfamiliar objects, which has been widely reported in rat populations in particular.

Populations that display the highest levels of neophobia tend to be those in stable environments that are less frequently disturbed and where there is an abundance of food.

Selecting a rodenticide bait that better manages the neophobic responses exhibited by rodents can greatly improve rodent management programs.

Winter Season Sends Rodents, Other Small Pests Indoors
As the leaves change colour and the crisper weather arrives, many small pests will begin to look for shelter indoors – and homes are the perfect refuge from the cold winter ahead. A1 Pest Control reminds homeowners of the importance that exclusion can play in keeping pests such as rodents and other small animals from becoming unwelcome houseguests during the winter months. It’s that time of year that temperatures are dropping so you may have noticed mice starting to enter your home.
Here Are Some Hints for Keeping the Mice Out
Exclusion is the most successful and permanent form of home mouse control. Seal all gaps larger than 6-8 mm around entry points into your home with wire, caulk or other building materials.
Your yard should be free of debris. Ideally your wood pile should be away from the house.
Remove weeds, rake leaves out away from the house, secure wheely bins and garbage bins and try not to have them in your garage.
If you store dog food or bird seed in your garage have it in a sealed container. And if you are having problems with mice please call, we’d be happy to help.
Rodents will always be looking for a nice comfy nook in your house to set up their own home!
Who needs them and who invited them anyway? Apart from spreading disease and fear, they can also cause other problems to your home and business. 
The biggest pest species found in Sydney’s Hills District, North Shore, Inner West and Northern Beaches are the brown Norway Rat and the Black (Roof) Rat.
 The most important and prevalent rat in the Hills District, North Shore and Northern Beaches is the Norway Rat.  A large bodied brown rodent, it is also referred to as a common or street/sewer rat. You will be aware of infestations through evidence of gnawing and an abundance of blunt ended droppings.
 The average length from the tip of the nose to the end of the tail, which is quite short in relation to the rest of the body, is around 40 centimetres long and they can weigh up to 340 grams. Their fur ranges in colour from reddish brown to dark grey and due to high variation amongst rats, fur colour is not a reliable way to tell one rat from another.
 Even though the Norway rats have only small ears their hearing is fine tuned and highly accurate. Not so their sense of sight. Relying on their keen sense of smell and taste, their eyes perform poorly and they are colour blind.  Rats are what is called `crepuscular’ creatures, which means they are active around sunset and sunrise, but not during the day or the middle of the night.  Norway rats are known to be exceptional leapers, runners, and swimmers as well as being capable of climbing pipes, bricks and tree trunks.
Contrary to its name, the Norway rat is originally from Eastern Asia but was readily spread by human movement over the last few centuries.  It is especially adept at living with humans and tends to thrive in both urban and rural settings.
 Norway rats tend to dig their burrows into the soil to use them as a shelter. Nesting sites within these burrows are common.
 Within cities, they use the same tactics, using drains, sewers and holes in construction sites as homes!
 Managing rodent infestations is usually a combination of exclusion (sealing up places that allow rats to come in and out of your house), trapping and baiting.
 Rodents are quite crafty and complex and control of rats is a serious business that is best left to pest management professionals, so please call A1 Pest Control on 0417 251 911 or email bruce@A1PestControl.com.au if you are finding evidence of rodents in your home!
More Tips!
 Did You Know: 
    • Mice are the number one cause of unexplained fires because of their tendency to gnaw on wires?
    • Mice can contaminate food and transmit various pathogens, such as Salmonella, the causative agent of food poisoning, by walking across various foods or food preparation surfaces?
    • Adults can produce nearly 40 offspring per year over four litters.
    • Rodents carry disease, cause fires and property damage.  
    • The real concern is that rodents and other smaller pests pose serious health threats by contaminating food and transmitting bacteria.
    • Mice and rats can spread diseases like Salmonella and Hantavirus. 
    • Rodents also put homes at risk for electrical fires by gnawing on wires and cause leaks by chewing through water lines.
    • We know that exclusion (pest-proofing) is not always easy, but it’s important for homeowners to spend some time over the next few weeks taking steps to protect their properties from dangerous pests.

To Prevent Rodents From Inhabiting Your Home:

  • Restrict all potential sources of water, especially dripping taps, leaking pipes and pooled water in your sub-floor.
  • Firewood and long grass provide perfect havens and hiding places for our furry friends. Store firewood well away from the house and keep grass and shrubs cut short.
  • Inspect all incoming food items before bring inside, store grain and cereals in airtight containers.  Get rid of garbage promptly and make sure all bins are sealed and kept away form your home..
Prevention is critical in protecting you business from a pest infestation. 
  • Below are some tips to use in your commercial business which will help you avoid health and property risks that come with rat and mice infestations.
  • “Pest-proof” your business by being vigilant of building maintenance needs.
  • Dispose of garbage regularly and store in sealed containers.
  • Repair any cracks, holes and gaps on the exterior walls of your business, including any potential entry points of water pipes and electrical cables.
  • Consult a plumber to rectify drainage and water leaks. Instruct the plumber to construct gutters to channel water into drains and away from your building.
  • Be sure your employees keep food sealed and stored properly.
  • Clean high-volume areas daily, such as public eating areas and kitchenettes, where crumbs and rubbish are more likely to build up.

Rodent Control

Rodents (Mainly Rats & Mice)

Article author: Bruce Gow

Mice and rats are, alongside mankind, essentially the most effective creatures on the planet when it comes to selection as well as range. Mankind has unknowingly assisted their distribution through the entire word through exploration. Nevertheless, they’ve in certain conditions turn out to be his worst type of adversary.dead-rat

Vast amounts of money annually is sacrificed through contamination of foodstuff through rodent excrement, urine as well as fur. Rats ruin a lot more foodstuff compared to they might possibly consume, and also their eating routines via gnawing have been to blame for producing fires in roofs. Rat control particularly is a growing pest problem in Sydney.

They multiply so rapidly, that inside a calendar year a rat may have among 30 and 80 young, depending on species -one couple might produce 15 thousand rats in their life span. Rodents may press via a opening the dimensions of a twenty cent piece, drop twenty metres without injuries, tread water for three days, consume a variety of foods and endure an atomic bomb blast. This can make it a bit tricky if you don’t know how to properly get rid of mice and rats.

The Benefits From Rodent Control in Sydney

There are many good reasons for treating Rodents, here are a few good points:

1. Prevention of money loss; the cost of damage by rodents is difficult to estimate, but is huge.
2. Prevention of damage; almost every type of food commodity whether in production, store or use is subject to rodent attack. Damage is also caused to the fabric of buildings, to electric wiring and plumbing.
3. Elimination of contamination; in addition to foods consumed, a vast quantity is fouled and contaminated by rodent droppings, urine and hairs.
4. Prevention of loss of goodwill; articles damaged by rodents and fouled by their droppings are unacceptable to the trade and to the public.
5. Prevention of disease; rodents carry a number of diseases injurious to man and domestic animals.
6. Conforming with law; it is an offence under the Prevention of Damage by Pests Act (1949) to knowingly harbour rodents in any premises. In food premises it is also an offence under various Food & Drug acts. Under the Health and Safety at Work Act all work places must be kept free of health hazards.
7. Relief from fear; the presence of rodents causes unnecessary distress and psychological harm to some people.
8. Improved employee-employer relationship; working conditions are an important consideration in keeping employees contented.

Species of Rodents


Roof Rats

AKA scientific name of Rattus rattus or common name of black rat or the ship rat is accountable for the Black Plague and the death of millions of people from its flea. Its capability to clamber distributed it all through the planet by clambering boats hawsers. It prefers to reside in trees and shrubs and roofs of buildings.


Norway Rat

AKA scientific name of Rattus norvegicus or Brown rat prefers to dig (unlike the roof rat) and also favours to dwell in close proximity to drinking water and damp areas. The Norway Rat carries a stouter frame and has a tail that is not as long. Is ears are also not as big when in comparison to the roof rat.

AKA scientific name Mus domesticus. Having a mouse problem tends to be a very much bigger monetary issue compared to rats in Australia, with population densities achieving 32,500 per hectare in plagues. They demand significantly less water than rats, with a shorter pregnancy period plus from 42 days, are at nearly 1/2 the proliferation maturity of the Roof rat.

Mice are distinguished from young rats by way of smaller heads and feet, bigger ears in proportion, and significantly longer tail.

Pest Control & Pesticides (Rodentiticides): Baits & Lures -Since the 1940’s chronic anti-coagulants have superseded Thallium, Strichnine & Arsenic Trioxide as a poisonous lure. Since the previous 10 or so years, rodents have become largely immune to Warfarin. Strains of rats can make it through a dosage that is several times more powerful only 10 years ago. Some strains of mice appear typically untouched by it at all.

A major advance in rodent control took place in the 70’s with the breakthrough of Brodifacoum & Bromadiolone, though resistance is actually commencing to take place. It is worth noting that the roof rat likes succulent meals (make use of liquid baits) and Norway Rats like dried foods (use cereal lures)

Detection of Rats and Mice

Any serious attempt to control rodents in buildings must, of necessity, begin with a thorough inspection of the premises. Technicians should take any opportunity to inspect premises at night when the activity may be directly observed. Signs of activity observed during the day must be interpreted to yield as much information as possible about the type(s) of rodent present, the extent of their activity, their routes and the approximate size of the population, and any other information that will aid in the determination of proper and effective control procedures. The following signs of rodent activity can be of great value in providing such clues:

Droppings – Droppings aid in identifying the rodent species present. When shiny, dark and pliable, they suggest very recent activity. Usually, within 2-3 days they become dull and hard as they dry out, and after some time they may be attacked by insects. Consider cleaning up droppings from particular areas, so that a later inspection will more easily indicate the presence or absence of continued activity.

Runways and rubmarks – These are greasy smear marks on surfaces that accumulate from continual contact with dirty, greasy rodent fur. Usually, they are most apparent on vertical surfaces, and they are very useful for the placement of traps (baited or unbaited) and bait stations and for rodent-proofing procedures. When covered with dust or cobwebs, they probably indicate no current rodent traffic.

Burrows – Burrows are often present adjacent to waterways (e.g. streams, canals) and buildings. Rat burrows generally have a ‘bolt hole’ hidden under grain or debris. If cobwebs or weeds are seen in the entrance, it is likely that activity has ceased.

Gnawings – Rodents must gnaw to keep their incisors down. They tend to gnaw a wide variety of materials, including woodwork, soft metals, soap food containers, conduit and cables. If fresh gnawings may be seen beside and below the chew marks, it indicates recent activity. Gnaw marks in old buildings could almost be as old as the building.

Nests – Nests may be found in hidden parts of constructions. They are usually made of rags. Paper, cardboard, strwa and the like, and if fresh droppings are present, they are likely to be active. collections of foods, even snail shells, may indicate the proximity of rat-nesting areas.

Runs – Outdoors, constant rodent traffic may pat down vegetation to form a rather obvious run. Indoors, dust free runs in otherwise dusty areas may indicate constant traffic.

Tracks – Footprints and tail marks in dust – covered floors and roof voids confirm rodent activity.

Urine stains – Rodent urine fluoresces when a black (ultraviolet) light is shine onto surfaces contaminated with it. Rat urine often appears like sprinkling over the areas traveled on. Care should be taken with the use of a black light, as some materials other than rodent urine also show fluorescence.

Urinating pillars – Long-term activity of mice sometimes leads to a build-up of urine, grease, dirt and dust to form small mounds or ‘urinating pillars’.

Disappearance of food – Rats often carry food away to their nesting sites.

Sounds – Occupants of building may draw attention to sounds heard during the evening and night. These are often described as bumping, squeaking, gnawling, clawing and sometimes fighting.

Odour – The long-term presence of a rodent infestation usually creates a distinct odour.

Visual sightings – Occupants of buildings sometimes report sightings of rodents during the day. This often suggests a large population or food shortage.

Excitement of pets – Most pets are territorial and very sensitive to foreign odours, noises and so on. Pets such as dogs may become very excited about the intrusion of rodents, sometimes clawing and barking at the part of the building where rodents are active.

All of these clues, gathered during thorough inspection and perhaps during conversation with the building’s occupants, will help to establish your approach to managing the rodent problem.

Rodent control Methods.

Technicians called on to manage rodents infesting a building should propose a combination of methods, depending on the circumstances. Procedures may include the following:

  1. Sanitation – Reducing the food and shelter available for rodent activity.
  2. Rodent proofing – altering the building structurally so that rodents cannot gain entry.
  3. Trapping – using traps or glue boards to physically capture rodents.
  4. Chemical control – Which may involve a variety of chemicals and techniques:

a) Baiting: with acute (single-dose) poisons; with multiple -dose anticoagulant rodenticides or with single-dose anticoagulant rodenticides or with single-dose anticoagulant rodenticides.

b) use of tracking powders (poisonous dusts) or gels.

c) Use of fumigants (poisonous gases).

The control of some high health risk, large-scale rodent infestations usually requires the implementation of several of these procedures. In dealing with all rodent problems, however, irrespective of the type of chemical control or trapping undertaken, the observant technician will always look for signs of poor sanitation and hygiene practices that, unless corrected, will continue to invite rodent problems.

How to get rid of Mice

Mousetraps- if you find mice in your house, then there are a bunch of different mouse traps such as snap boards & tacky traps need to be applied as a back-up for lures, or for basic safety reasons. They ought to be put just out from skirting boards, with the bait on the trap close to the walls. I usually use cocoa powder sprinkled on some fresh bread. It may be smelled some distance away and mice love it. Tie the bread on to the metal tab that holds the bait with some cotton thread. Pulling will set off the trap. You can read more about traps as a method of rodent pest control.

Gassing- Is used for outdoor burrows, in boats and grain silos by the usage of fumigants. This is a popular method of mice and rat poisoning.

Prevention- In pest control this means the stopping of entry locations by mechanics means such as bird wire, aluminium sheeting, steel wool or door closes.

Contact Dusts and Gel- Tracking powder or gel may be used where the activity is situated. You can see where they travel and determine this by using a well known D.Y.I. household tip by the usage of talc as a tracking dust.

Prevention: High hygiene standards and limiting the availability of food and water is an important measure in limiting the amount of attention your home will get from rats and eventually lead you to the point where you need to know how to catch a rat.
Natural Countermeasures & Eco Friendly Rat Control

If you’re after a non-toxic and natural approach to rodent control then the following repellents are suitable as they are often used to repel rats:

•Napthalene Balls – these are very easy to acquire and when placed properly in problem areas around your home and property they can act as a natural deterrent. Rats dislike the scent they emit and will actively avoid it.

•Another natural scent which serves as a deterrent would be natural oils. Oils such as citronella/peppermint give off a powerful smell which can be a suitable deterrent.

•Electronic wave emitters are becoming very popular however, their efficiency is not proven yet and they seem to be a “hit and miss” option. They serve by emitting a strong frequency that deters rodents from coming near your property.

• Pets are also fantastic countermeasures for rodents as a cat or dog would go a long way as rat catchers! Sydney pet lovers have someone onside to help with natural enemies of rodents.

Natural Chemical / Poisons

As rats have developed over many years they’ve managed to develop a resistance to many conventional poisons and treatment methods. Some naturally occurring veggies that are poisonous to rats are:

•Sweet Potatoes (raw)

•Dry beans (not cooked)


Mixing some of these and spreading them around your property could go a long way in preventing a rodent infestation and killing off some that might already have made your home theirs as well. Please note that though these methods can be effective against a limited rodent presence we would recommend a professional approach and treatment if there is a rodent infestation or they keep coming back after you take measures against them.

How to get rid of Rodents

In Australia we mainly find two types of Rodents, the Norwegian Rat and the Roof Rat. The way we can tell the difference between the two is by looking at their droppings. The way we treat there Rodents are the same, it just depend on the situation. There are two ways to treat rodents namely non-chemical treatments  and the chemical treatment.

Non-chemical control.


It is quite reasonable to think that decreasing the food and shelter will lead to conflict between the rodents and will eventually decrease the numbers in population. After a thorough inspection of the clients property, the technician will be able to advise the client what may need to be done in order to make the property less desirable for the rodents by doing things like changing the bins to ones with tight fitting lids, a general clean up of the rubbish and overgrown weeds around the building. The technician might want you to do this right after the treatment or the following morning. Every situation will be different and maintaining a high level of hygiene is directly in relation to the control and prevention of rodents.


One of the most permanent methods of rodent control is to make alterations to the building to prevent rodents from entering. It is important to know that any cracks, crevices and holes can be access for rodents to enter the house. These should be blocked by using sturdy and durable materials, materials such as plastics and wood should not be used as rodents can chew through these. Some building has too many holes and crevices that it would not be economically feasible to proof the entire building. in some cases proofing might actually be a cheaper option if you consider long term treatment.


Trapping can be time consuming and require some skill but in some cases trapping would be the best option in the following situations: Where inaccessible dead rodents cannot be tolerated, for premises where chemicals are not tolerated and for getting those ‘bait-shy’ rodents that’s left after a baiting program. There are a few different trapping options such as simple snap traps and glue boards. Simple snap traps require a bait such as bacon, fish, nuts etc. to encourage the rodents to investigate and be trapped. Glue boards usually contain an attractive scent that attract the rodents, these traps must be placed where dust can not settle on the surface.

Chemical Control

Tracking powders and gels.

Rodenticides are available in powder and gel forms. These need to be placed where rodents are likely to contaminate their paths like along runways or in burrows. Over a period of time rodents will ingest the poison witch will lower the numbers of the population. When using these powders and gel, one should be careful not to place it in places where the rodents can carry this poison into the house or where food are stored.


Fumigation would be used if there is a large infestation of rodents or where a rapid elimination of rodents are required. Fumigation is very dangerous and can only be carried out by a licenced technician.


Rodents suffer from ‘neophobia’ witch meant they know their immediate environment well and tend to avoid new objects. This means in some cases the house needs to be pre-baited to get the rodents to get used to new object and feed from it freely before it gets altered with poison.

Multiple-dose anticoagulants.

A lot of the rodent work in Australia is done using this method. This treatment lets the rodents feed of the bait for several consecutive days before the rodents exit the house in search of water due to severe dehydration witch leads to death. This may take anything from 4 to 10 days. These baits should be placed where rodent activity is visible and where possible the baits should be in an enclosed area to afford coverage and protection to the feeding rodent. Lockable or tamper proof bait stations are often preferred and sometimes required for safety reasons.

Types of formulations.

anticoagulant rodenticides may be obtained in various forms:

  1. Concentrates – Used in the preparation of food or liquid baits, or perhaps as a tracking powder.
  2. Ready-to-use baits – mostly in the form of treated whole grain or pallets, available in bulk or ‘throw pack’ form.
  3. Paraffin blocks – Usually treated grain in matrix of paraffin wax, suitable for situations with excessive moisture.

Anticoagulant rodentcide bait, even through safer than single-dose poisons, should be placed so as to be inaccessible to pets, children and other non-target animals. where ‘throw packs’ (small amounts of treated grain prepackaged in plastic bags) are used, these should be placed unopened in areas inaccessible to people and pets, allowing the rodents to open them before feeding. Bait shyness does not usually develop, as the slowness of poisoning in not really associated with bait intake. Daily inspections and topping up are advisable for the first three days, until feeding requirements are known. Where baits are in trays, smoothing the level of bait will help to determine whether feeding is taking place. Bait should be removed when no longer required, as they may attract and facilitate the breeding of various stored-food beetles and moths.

Single-dose anticoagulants.

Research into anticoagulants rodenticides has led to the development of pesticides that, while having the same mode of action as multiple-dose anticoagulants, give good control in small amounts and single feedings. A single lethal dose ingested by a rat will cause death in 3-7 days. The toxicity hazard of these ‘ second generation’ anticoagulants is more akin to that of traditional acute poisons; but because their mode of action is interference with proteins produced by their liver’s formation, they have an antidote – vitamin K1. Nevertheless, as these materials are toxic to warm-blooded animals as well as rodents, great care must be exercised.

Safety precautions in rodent control.

  • Always read rodentcide product labels prior to use and use in accordance with label information.
  • When preparaiton or handling rodent baits, wear protective clothing and equipment (including respirator, to protect against inhalation of fine dusts or vapours, and gloves to protect against skin contact)
  • Baits should be placed so as not to allow access to them by children, pets, wildlife, domestic animals and livestock. Specially designed bait containers are available and should be used.
  • All bait stations and containers should be clearly marked ‘POISON’
  • All ocupants of the building (e.g. employees, residents) should be notified about the placement of poisonous.
  • Baits should be placed where they can always be retrieved.
  • A record of bait placements should be kept to facilitate comprehensive checking and/or later removal.
  • When handling dead (or near dead) rodents, wear gloves and consider using insect repellent to lessen risks of bites by ectoparasites (e.g fleas).
  • Do not place baits or tracking poweders where their disturbance could cause contamination of food, or food preparation and handling surfaces.
  • Inspect bait stations regularly and remove baits when rodent activity ceases.
  • Destroy old rodenticide containers and untaken bait.
  • Do not contaminate ponds, waterways or drains with rodenticides or their containers.
  • If rodenticide contacts your skin, and even if it hasn’t, on compeletion of baiting, wash thoroughly with soap and water.
  • Do not eat, drink or smoke while handling baits or tracking powders.
  • Wash gloves and contaminated clothing before re-use.
  • Do not give or sell rodenticides to clients.
  • Store rotenticides in original containers, tightly closed and in a safe place.
More Facts About Rodents  

Rats are very much creatures of habit, tending to use the same routes of travel to and from food sources for as long as possible. They are sometimes referred to as being ‘neophobic’, suggesting they have a fear of new objects or changes in their familiar environment. This behaviour can be the cause of their apparent disinterest in a new bait station, at least during the first few days of its appearance.

Mice, on the other hand, although seeming to maintain a high degree of caution in their movement, are very curious and adventurous animals. They often investigate new food sources within a very short time after its appearance and seem to prefer nibbling at small amounts of food at various locations. This preference for feeding at several different sites is to be taken into account in mouse-baiting programs.

They are excellent climbers and may easily climb walls, brickwork, pipes and run along cables. Rats are natural swimmers. What can be shocking to some people is that they can pop out of toilets after negotiating the S-bends!.

Some biological control of rats and mice is effected when they are preyed upon by cats, dogs, snakes and some bird species.

The plague bacterium (Yersinia pestis) was transmitted from rat to rat (ship rats) and from rat to human by the Oriental rat flea. The incidence of plague has not been entirely wiped out but, closer understanding of the mechanism involved has seen much reduction in the occurrence of this dreaded disease.

Among the many disease transmitted to humans by rodents, some of which are outlined in table 1.0, perhaps the most insidious and widespread problem involves the distribution of food-poisoning organisms, particularly Salmonella bacteria. Unfortunately, the nature of disease organisms of this type is such that it will always be difficult to pinpoint without any doubt, the cause of disease transmission. It is very likely that rats and mice play a significant role in the transmission of gastro-intestinal diseases, which are somewhat difficult to track back.

Brown Rats Distibution in Australia

Distribution of brown rats in Australia

The Norway/ Brown rat is the largest of the commensal rodents in Australia, with its distribution restricted to human coastal settlements.

The species is often found inhabiting ware-houes, shipping ports and large urban settlements and, more than any other rodent species, it has adapted to utilise human food and wastes. In Australia however, the species has not been successful in colonising agricultural systems; only a few systems report minor damage due to brown rats.

Brown rats can be distinguished from other rattus species by its size, small ears and thick tail which is usually shorter than its body. Its coatis variable like the roof rat, ranging from grey to brown above with a white or grey belly

Occasionally, albino and pure black individuals occur. Compared to the rood rat, the brown rat has a scruffy appearance and a very aggressive nature, not hesitating to attack when cornered.

Brown rats are poor climbers however, they can reach elevated areas if the correct structures are present to aid climbing
