Pest information

Cockroaches

Fast, flat-bodied insects that hide in warm, damp gaps and come out at night to feed. A few introduced species cause most household problems in Australia.

Ants

Social insects that live in colonies and follow scent trails to food and water. Most ant problems in homes are nuisance foraging trails from colonies outside the house.

Mosquitoes

Small biting flies that breed in still water. Beyond itchy bites, some Australian mosquitoes spread viruses such as Ross River virus, so reducing bites and breeding sites matters.

Fleas

Tiny, wingless, jumping insects that feed on the blood of pets and people. Most of a flea population lives in carpets, bedding and yards as eggs, larvae and pupae, not on the pet.
