When a termite colony reaches a certain size, termites spread out to start a new colony. This practice, known as swarming, allows termites to branch out into new areas. It’s crucial to their survival as a species. If you find a swarm in your home, there’s likely an established colony nearby. This is especially problematic if you find a swarm in the spring. Here’s why:

Best Conditions for Flying

Flying is the first step to swarming. When the conditions are perfect for flying, alates (aka swarming termites) get ready to swarm. Termites only need to swarm about once a year, so waiting for the optimal time is not an issue. Swarming season for subterranean termites is always in the spring, while other termite species prefer summer or fall. 

Warm Weather

Termites can’t survive freezing temperatures, so they tend to stay underground in the winter. However, termite colonies continue to grow all year round. As winter turns into spring, termites prepare to spread out. Spring has the perfect balance of temperate weather and rainfall. Swarming typically starts after the last freeze of the winter season.

Damp Soil

Soon after the last freeze of winter comes the first rain of spring. This creates the perfect opportunity for termites to swarm. The damp soil creates the ideal conditions for nest building, an essential step in growing the colony. Survival rates among termites are also higher when there’s more humidity. Swarming in the springs allows termites to build colonies and lets the colonies thrive.
