Q: Why are infestations often discovered during March – May?
A: Spring typically is when large numbers of winged termites, known as “swarmers,” termite swarmersemerge inside homes. In nature, termites swarm to disperse and start new colonies. Triggered by warmer temperatures and rainfall, the winged termites emerge from the colony and fly into the air.
Above: Winged termites emerging indoors are a sure sign that the building is infested.
The swarmers then drop to the ground, shed their wings, pair off with a mate, and attempt to begin new colonies in the soil. Few swarmers emerging outdoors survive to start new colonies. Swarmers emerging indoors are incapable of eating wood, seldom survive, and are best removed with a vacuum. They do, however, indicate that an infestation is present.
