In addition to distinctive wing sizes, termites and flying ants can be distinguished through their body shape and antennae. Flying ants have two body sections that are connected by a narrow waist. Termites have a straight body with a broad waist. Their antennae differ as well; ants have bent or crooked antennae, and termites have straight antennae. If there is still a question about the differences, call a professional in termite inspection. He or she can identify and suggest the right treatment to exterminate whichever insect is present.
