Ant Infestations Around Australian Homes

Ants are the pest Sydney homeowners ask about most in the warmer months. A trail of them across the kitchen bench seems to appear overnight, and no amount of wiping keeps them away for long. The reason comes down to how ant colonies work, and why the usual supermarket spray often makes the problem worse.

Why ants come indoors

Ants forage constantly for food and water, and a warm Sydney home offers both. Sweet spills, crumbs, pet food and even the moisture around a leaking tap are enough to bring a trail marching in. After rain, colonies also move to higher, drier ground, which often means indoors.

Know your species

Getting the species right matters, because different ants respond to different methods.

• Black house ants are the small shiny ants trailing after sweet foods
• Coastal brown ants nest in soil and push up small piles of dirt between pavers
• White footed house ants form very large colonies inside wall cavities
• Argentine ants build enormous connected supercolonies and are particularly hard to control

Why sprays often backfire

Spraying a visible trail kills the workers you can see, but it does nothing to the nest, and with some species it triggers the colony to split and form new nests. That is why a problem seems to get worse after a heavy spray. The workers on the surface are a tiny fraction of the colony.

How professional ant control works

The effective approach is baiting. Slow acting baits are placed along active trails and near nests, and the workers carry them back to feed the colony, including the queens. It takes a little longer than a spray, but it removes the colony at the source rather than just the ants on display.

Prevention tips

• Wipe up spills and store sweet foods sealed
• Keep pet bowls clean and dry between feeds
• Seal gaps around windows, doors and pipes
• Fix leaks and reduce moisture around the home

Frequently Asked Questions

Should I clean the trails away before treatment?

No. The trails help us place bait exactly where the ants are actively feeding.

How long does baiting take to work?

You may see activity for a few days as workers carry bait back, then the colony declines over one to two weeks.
