Rat Control Sydney


We use the very low toxic rodenticide Selontra for rat control in Sydney. Our technicians conduct a very thorough pest inspection before the treatment, looking for rat droppings (rat poop) in the areas that these rodents love to take shelter.

It’s important to know the difference between rat poop and mice poop, as we need to know how much bait and what bait stations to use in our safe baiting programmes.

See our photos below of the difference between rat poop and mice poop.

Key benefits

  • A low toxic rat bait that is highly palatable and a soft stable formulation
  • It works differently to other traditional baits in that is a non-anticoagulant active which does not accumulate in the environment
  • It works much faster with a superior performance – to get rid of rats up to three times faster control than older anticoagulant rodenticides
  • Less bait is needed to control rats and mice quickly

How it works

The active ingredient (cholecalciferol) in Selontra is not persistent or accumulative in the environment. It controls rats and mice safely  up to three times faster than traditional baits.

Colecalciferol is a much safer bait to use as it is a type of vitamin D made by your skin when it is exposed to sunlight. It has a warning dye and bittering agent that deters humans from eating it, yet is undetectable to rodents.

It is commonly used as a vitamin supplement and also found in some foods.

Cholecalciferol kills rodents in high doses as rodents don’t process it as well as most mammals and it can produce in them a condition known as hypercalcemia.  This results in systemic calcification of their soft tissues. This will lead to kidney failure and cardiac arrest.

Studies on birds have revealed that they are approximately 50-times less sensitive to cholecalciferol than rats and mice.

It has a much less risk of secondary poisoning.  Scientific studies on 0.075% / 0.08% cholecalciferol baits have revealed no signs of poisoning in the pet cats, dogs and birds that were tested.*

Highly Stable

Selontra is highly stable and doesn’t melt in hot weather or crumble in cold weather, like most other rodenticides. Scientific studies have shown that it works up to 3 x faster than other rodenticides and has a stop-feed property. It makes rodents less hungry after lethal doses and lets sub-dominant rodents feed to mortality.  This leads to 100% control much faster.

Rat Control in Sydney for Commercial Premises

Do you need to speak to someone about rat control? Whether you own commercial premises in Sydney Hills District or a suburban home, rats are rodents you really don’t want to share your space with. They’re more than just ugly (sorry kids!) they’re disease carrying pests that have been responsible for the deaths of millions of humans over the centuries, from a variety of diseases.

From the Bubonic Plague that has killed millions around the world to Leptospirosis – the illness that killed Olympic rower Andy Holmes in 2010 – the types of bacterium spread by rats can cause serious illness and sometimes, death. Leptospirosis can be contracted by humans when they come into contact with contaminated water; and the water is contaminated by urine from infected animals or rats. Those who have open wounds or cuts or get the water in their eyes or mouth may be at higher risk.

You may think that such diseases are rare in the modern era but according to a NSW Government Health Department fact sheet, there are some 200 cases of Leptospirosis diagnosed in Australia every year, and it is suspected that many more go undiagnosed.

Rats can do quite a bit of damage to property too – as many people who have stored old paperwork, clothing or other fabrics in cardboard boxes in a storeroom, shed or garage can tell you! And of course, they don’t mind stealing some of your insulation to make their nests cosy.
Rats tend to move into buildings where there’s a food source close at hand but rat control is important for all commercial premises, even those that don’t have a food store, canteen, or food storage area. If you’re near premises that do, and rats are moved on from those premises either by a rat control treatment or by access to their food source being eliminated, they’ll be looking for a new home nearby.

Whether you own commercial premises or a suburban home, there are a few basic rat control measures you can take on your own to reduce the risk of rats taking up residence:

• Ensure that all food stored on the premises is sealed.
• Seal all bins tightly where this is possible.
• Remove rubbish from inside the premises regularly.
• If you store materials that rats might find useful for nest building, secure it in strong plastic storage containers rather than cardboard boxes or plastic bags that can be chewed through.

Pest Control Rats Extermination

How to get rid of rats

“Don’t be daunted by something as extensive as organizing a rats extermination process, at A1 Pest Control we are well versed in the art of eradicating rats and keeping them from seeking future refuge in your home or business establishment. Ring us up today for a risk free quote or to arrange an appointment.” – Bruce Gow and the A1 team

Friendly to the environment methods to maintain rodents away from your home.

Rodents can be quite a serious problem for just about any house owner. Not only large rodents, rodents may distribute disease and destroy your home. Traditionally the only way to get rid of rodents was to make use of poisonous chemicals which were environmentally insensitive and potentially harmful when inhaled by humans. More recently a number of environment friendly subjects annihilation techniques have been created which can allow you to free your home of those unwanted infestations without risks for your well being and for the environment.


Rat repellents can be found in a number of different varieties and can be familiar with deter rats through setting up camp in your home. There are a number of normal rat repellents which usually don’t utilize harmful chemical compounds. Some of the most commonly used ones tend to be:

  • Naphthalene
    balls – these are easy to purchase and can be tactically put about your home. Rats don’t like the scent associated with naphthalene and could end up being effectively deterred because of this.
  • Use important essential peppermint and also citronella which emit a powerful aroma and may be an effective prevention to mice.
  • Electronic sound products produces a sound wave that might stop rats from getting near to the office space.
  • Get the family puppy. Dogs and cats can be excellent rat-catchers and frequently their really reputation will keep rodents well away.

Rat Poisons:

Poisoning rats needs to be carried out by professionals as these rodents are extremely proficient at becoming resistant in just a few generations to traditional kinds of poison for rats.

Should you be  looking to hire a professional pest control firm, make sure the company that you hire is licenced, OH & S compliant and insured. The safety of your staff, children and pets such as dogs and cats is essential. 

If you suspect there is a rat issue it is always a good idea to look for professional advice.

Call us on 0417 251 911 for more info, or to chat about your situation.

One of the most common types of rodent poison has the active ingredient brodifacoum.

How does the rodenticide brodifacoum cause the poisoning of rats and mice?

Brodifacoum drastically reduces Vitamin K in the body of mammals which may lead to a decreased blood clotting ability. If this clotting ability is reduced to a level which is  significant, profuse internal bleeding can occur.

How much rodenticide do you need to ingest to the point where you are poisoned and get sick?

This varies from person to person as people have different levels of physical fitness, size, body shape, genetics and age. A large amount over 30-50 mg would need to be eaten to cause sickness from poisoning. This is equivalent to 6-8  teaspoon sized doses.

A child or a pet who have eaten a large mouthful bait have been known to have become ill or developed internal bleeding problems.  

Make sure that your child or pet cannot contact any rodent bait and always ask for information where the baits are located.

We normally supply a map as well as giving verbal advice after a baiting programme has been installed.

Signs of Poisoning and Symptoms: 

Signs of pet poisoning may include, but not limited to, blood in the urine, weakness, persistent coughing, breathing difficulty, seizures, and confused walking.

The active ingredient found in a lot of pest control firms’ rat bait poison is brodifacoum.

We typically use the very low toxic rodenticide Selontra.


The only antidote for poisoning is vitamin K. How much antidote depends on the condition and you should consult a medical practitioner for appropriate advice. Treatment may be needed long term.

Help and assistance: 

If you think that a person or pet has been poisoned, call the Poisons Information Centre. Advice is always available at any time of day or night on 131126 from any location in Australia.

If a person is concerned that they may have consumed poisonous food, they should contact a doctors or ring 000 for emergency help ASAP.

"We first used A1 Pest Control a few years ago when we noticed a few termites under a wine barrell in the rear yard of our home. We asked A1 Pest Control Sydney to pay us a visit to have a thorough termite inspection of our home. Bruce and his crew were on time, and very well presented. They explained how they would get rid of the termite infestation using a low toxic method and how their Thermal cameras worked, It worked very well and now we can sleep at night!"
Gary and Carol Harman
"We have been using Bruce form A1 Pest Control for over 4 years now. We bought our new house on the Hills Area, and moved in. our neighbours had problem with rodents and spiders so they are using A1 next door. I asked them if they could come over and treat our house too, as i didn't want to chase pest around our home. The service was not only effective, but carried out without any smelly fumes that we have experienced in our last house. They solved problem next door and I haven't seen a bug since."
Melissa Topper
"A1 Pest Control exterminators where great! I'm very happy to say that they solved a bed bug problem that I had after we had visitors from overseas visit us. I would recommend A1 Pest Control to anyone needing a safe and effective treatment of bed bugs"
Amanda Wu
"Bruce solved our commercial pest control problem in Castle Hill. Cockroaches were throughout our factory and they were completely gone after two visits from his exterminators. Just seeing one cockroach can lose us clients. I know now everyhing is ok, and our reputation is intact"
Raj Beri, Europa International
"Bruce from A1 Help us get rid of a bad spider infestation that have been troubling us for a while. It was done with low toxic spray and his crew even game me some cockroach and ant baits to get rid of them. I have recommended A1 to all my friends and family"
