Termites CAN fly.
More Info: During the adult state of a termite’s lifecycle, worker termites have wings and can fly. During the late winter or early spring, you may witness swarms of termites emerging to gather around a light source such as a door or porch light. Once they have swarmed, they will break off their wings and pair up with a mate. If near a home, the two will then attempt to find a spot to start a new colony where wood meets with soil.
If the swarm occurs within your home, it is unlikely that many will survive to start new colonies but is a clear indication that you have a serious termite infestation in need of a professional exterminator.
