Colonies of ants and termites both produce winged reproductives that fly out to start new colonies. Carpenter ant swarmers are quite large – about 3/4-inch in length. Termites and other ant species are usually 1/2-inch in length or larger. The key way to distinguish winged ants and winged termites is by examining the wings. Termite swarmers have wings that are all the same size. If the hind wings are much smaller than the front wings, you have ants. Collect a few and have them identified by a professional if you want to be sure.
