The start of the annual flight of reproductive termites
Termite exit holes are caused by termites annual reproductive flight. Every year mature termite colonies develop a special caste of termites called winged reproductives or “alates”.
These “alates” normally reach maturity in spring. The colonies then wait for a suitably humid day, often a very hot day with an afternoon thunderstorm to release all their alates through exit holes. The exit holes are typically located high in trees although sometimes they are located inside houses. When this happens home owners can be inundated with thousands of flying termites. Sometimes this is the first indication that a home is infested by termites.
Now you know what you can SEE, but what about what you CAN’T SEE ?
