Outside, pharaoh ants nest in shaded areas and underneath piles of organic debris. Inside, they like to nest in warm, humid areas that are located near their food sources. Indoor nesting sites include behind baseboards, behind wall voids, under floors, and even in furniture.
Pharaoh ants feed on things like sweets, oils, proteins, and dead insects. They will typically move inside or between homes and other buildings using electrical wires and cables as “roads”.
Pharaoh ants will nest and hide in very hard to reach areas in your home. They will also contaminate food sources, have multiple nesting sites, and, in general, will become a huge annoyance. This species of ant is particularly difficult to get rid of without professional help.
