Stop, Thief Ants!
Thief ants (Solenopsis molesta) get their common name because they steal larvae, pupae, and food from the nests of other nearby ant species to feed their own colony. They are also sometimes called “grease ants” because they like to eat greasy food, such as meat and cheese.
Thief ants are the smallest household ants in our area. They invade homes looking for food and more comfortable temperatures – warmth in the fall and cool during hot weather. They nest in cracks and crevices and wall voids, forage actively on set trails, and can be difficult to eliminate without the help of a skilled pest management professional.
