Often, a termite swarm may be the first or the most visible sign of a termite infestation noticed by a homeowner. Termite swarms can be difficult to identify because they often travel in large numbers. Instead of seeing individual termite swarmers, you may see something that resembles a buzzing cloud.
Swarming termites can be found indoors or outdoors. During an indoor termite swarm, alates often gather near light sources or windows, trying to find a way out of your home. If the swarmers can’t reach the outdoors, they’ll die within hours. This is often when homeowners will spot small piles of live insects or discarded wings around window sills or under light fixtures.
During an outdoor swarm, homeowners may see large clusters of alates buzzing around their property for up to 30 minutes at a time. That said, termite swarms don’t stay stationary — they exist to help termites reproduce, so they’ll move about trying to find somewhere new to settle and populate.
