Ant nests are often found in wall cavities, roof voids and gardens. Ants are considered a household pest because of their nuisance value, the risk they can pose to health and in some cases (coastal brown ants) because of their excavating habits.
Ants can be troublesome to control which is why it is often best to seek professional assistance. The most effective ant treatment is the destruction of the nest with a registered insecticide. However, good housekeeping practices can minimize a problem with an ant infestation. If you know where the ants are accessing your home, seal off any access points as well as ensuring there are no sticky spills in cupboards or food debris in cupboards or on the floor.
