One of the most common mistakes that people make is confusing flying ants with swarming termites.
Unfortunately, the similarities between the two make it easy for that to happen. Here are just a few things you can look for in the event you encounter either one.
First, swarming termites have two sets of wings of equal length, and they are considerably longer than the body of the termite. Flying ants will also have two sets of wings, one set longer than the other, and both sets are generally shorter than the ant's body.
Next, swarming termites have straight antennae, while flying ants have elbowed or "bent" antennae. Finally, swarming termites have a thick waist, whereas flying ants will have a constricted or "pinched" waist resembling that of a non-flying ant.
Hopefully, this will help you in identifying the pest you are dealing with.
