Determining whether you have flying ants, or winged termites is important in how you treat the problem. Some flying winged ants resemble the winged-swarming termite.
Here are some ways do identify the differences:
While both species have four wings, termite wings are uniform in size. Winged ants have noticeably larger wings in the front than the pair in the back.
Termites antennae are almost straight where the ant's antennae is elbowed.
Termite wings are twice as long as their body. Ant wings are shorter and more proportionate to their bodies.
Ants appear distinctly segmented, because of their thin waist. Termites have a broad waist and are mostly a uniform width along their entire body.
