These ants are frequent house invaders; often found around kitchen and bathroom faucets where they obtains water. Pharoah ants feed on sweets but prefer fatty foods. The ants also eat dead insects and prey on other insects. Pharoah ants are more common in warmer climates.
Residual insecticides are not useful because colonies tend to split. Baiting is the preferred management strategy.
