I found this printed on a business card from one the many pest control companies I have used.
Here are some ways do identify the differences:
- While both species have four wings, termite wings are uniform in size. Winged ants have larger wings in the front than than the pair in the back.
- Termites antennae are almost straight where the ants antennae are 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.
