Termite Swarms: What You Need to Know
A termite colony has to be at least 7 years old to produce any type of swarm. BUT! the larger the swarm is, the larger the colony that is attacking your home.
What Is a Termite Swarm?
A termite swarm happens when winged termites called alates leave their nest to mate and form new colonies. Attracted to light, they often gather around windows or light fixtures, especially after rain.
Why Do Termites Swarm?
Swarming is how termites expand. Once a colony matures, it releases hundreds or even thousands of swarmers to reproduce. Males and females pair off, shed their wings, and search for new spots to build a nest.
When Do Swarms Occur?
Subterranean termites typically swarm in spring during daylight hours.
What Should You Do?
A swarm is a major red flag that a mature colony is nearby—possibly inside your home. Don't ignore it. Even if it's small, schedule a professional inspection to stop damage before it begins.
