Winged termites are not a species of termite; they are a cast of termite. In a termite colony, these are the reproductive males and females that are responsible for creating a new colony. They are the first and last sign you’ll see that you have a termite problem.
Why do we say the first and last? These winged reproductives are only created after a colony has matured. If you are finding winged termites, there is a good chance that you already have a mature colony living inside the walls of your home. Where you find these swarmers and how many you find are indicators of whether or not they are the beginning of an infestation or one that has been going on silently for years.
How can you tell? If you find a few swarmers roaming around outside of your home, you could be okay. Swarms break up and termites will go off in pairs to start new colonies. Those might just be the kings and queens of a nest that has not yet begun. But, several dozen or more inside your home means your home is already infested.
Swarms happen quickly. Sometimes, the only sign that termites have visited your property, or that they are already living in it, is the shed wings they leave behind. These translucent white wings will often be found on inside window sills because swarmers are drawn to light.
