Key features and biology

The pharaoh ant is actually quite uncommon in houses or as a store pest within Oz. They have a two segmented waist similar to the coastal brown ant however, they lack a major workforce.

They are found frequently within hospitals and have also earned the nickname ‘hospital ant’. The Pharaoh Ant infests all varieties of foods. They are an ant species that has multiple queens within the colony structure (polygynous) and their nests can be interconnected (polydomous); it’s for this reason that their infestations are often quite large. Their queens live for only four to twelve months and the worker for approximately three months.

Their worker caste is (monomorphic) i.e. single caste. But their workers vary in sizes from 1.5-2 mm. The workforce might also forage over larger distance. Pharaoh ants also commonly nest within the structure of buildings, usually within wall voids, or more frequently in the warmer areas of the structure. Due to their large potential size of an infestation and the fact that they distribute throughout a building quite quickly they can be very hard to manage.

Food preferences

They are primarily a protein feeding species but are known to occasionally feed on sugars as well as oils and fats, though to a lesser extent.


Approx. 1.5 – 2 mm

“Ants could be a mere nuisance but can quickly develop into a vast infestation if untended. Don’t let it get to that point!” – Bruce Gow

"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!"

"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."

"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"

"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"
