When Do Termites Swarm and Why?

When Do Termites Swarm and Why?

If you’ve ever seen a sudden cloud of winged insects near your home — especially in the spring — there’s a good chance you were witnessing a termite swarm. For most homeowners, it’s alarming, and for good reason. Swarming termites are a clear sign that a nearby colony is mature and looking to expand.

Why Do Termites Swarm?

Swarming is how termites reproduce and start new colonies. Once a colony reaches a certain size, usually after a few years, it produces alates — winged reproductive termites. These termites leave the colony in large numbers to find mates and new places to settle. The goal is to establish fresh colonies, sometimes right near your home.

When Do Termites Swarm?

The timing depends on the species, but in general:

  • Subterranean termites (the most common in the U.S.) swarm in spring, often right after a rain when the air is warm and humid.

  • Drywood termites typically swarm late summer into fall.

  • Swarms usually happen during the day, especially around windows, doors, or outdoor lights.

What Should You Do if You See a Swarm?

Seeing a swarm inside your home is a major red flag. It often means termites have already established themselves in your walls, floors, or foundation. Even if you see one outside, it’s a warning that termites are active nearby — and your home could be next.

Here’s what you can do:

  • Don’t panic, but don’t ignore it either.

  • Try to collect a few insects if possible for proper identification.

  • Check around your home’s foundation for mud tubes, damaged wood, or other signs of termites.

  • Call a professional for an inspection — swarms are often just the tip of the iceberg.
