Pharoah Ant

Pharaoh Ant


The Pharaoh ant, which may have gotten its name from rumors it caused a plague in ancient Egypt, is widely considered one of the most difficult pests to control. It doesn’t really like the outdoors much, so it will move indoors to nest near warm and humid areas, in close proximity to food sources. Often, the Pharaoh ant will nest in such hard-to-reach places as wall voids, under floors and in furniture. The Pharoah ant will forage night and day and is a common problem in hotels, grocery stores, hospitals and apartment complexes – especially in hospitals, where it acts as a vector for such pathogens as salmonella and streptococcus. Like the Argentine ant, Pharaoh ant colonies have many queens and seem compatible with one another; they are less inclined to go to war than the more aggressive species of ants.


Because of the pervasive nature of the Pharaoh ant’s infestations, and the many places it will establish nests in a structure, containment and eradication are best left to a pest management professional. This is vitally important, because the Pharaoh ant colonies will splinter, or bud, into a number of smaller colonies, if sprays are used. Clark’s highly trained technicians have the expert knowledge to solve any Pharaoh ant infestations you may be experiencing.
