There are more than 700 ant species found in the U.S., although only about 25 species commonly infest homes. Ants are social insects that typically live in underground colonies, made up of workers and a queen. Ants will eat practically any kind of food, but are especially attracted to sweets. Ant identification is relatively simple due to their three distinct body regions: head, thorax and abdomen, as well as antennae. Despite similar construction, ants vary in overall appearance. Small or large ants and brown or black ants are common nicknames for different species.
If you do find signs of an ant infestation in your home, contact a pest professional promptly. They will be able to inspect your home, perform proper ant species identification, and recommend a course of ant control and extermination.
