Ants are social creatures who travel in great numbers. They prefer to live in places with moisture such as bathrooms, kitchens, and laundry rooms. Nuisance Ants have a three segmented section body, 1/8” to 1/4” long and are usually brown or black. They enter the home in search of food or water through openings around windows, doors, air conditioners, and crawl space vents. Nuisance ants are a common problem for home owners and populations can grow quickly so it is important to call professional pest control right away.
