These ants are about ¼ inch long, and the body is brown to dark brown with pale brown legs. The winged forms may occur during most warm months, but are most common in June and July. Nests are located in soil and in the masonry walls of houses.

(Tetramorium caespitum) These ants are common in the yard, garden and around foundations. They feed on a variety of plant and animal material. They forage primarily during the day. Nests between the block walls and the sill plate of houses often contain parts of insects and wood shavings.

The best control strategy is to locate and treat the outdoor nests with liquid insecticide, and to use bait for the indoor nests. Colonies that are foraging indoors will usually be located close to the house foundation.
