During which seasons are subterranean termites primarily swarming and mating?

Subterranean termites primarily swarm and mate during the spring and fall seasons. In the spring, rising temperatures and humidity levels trigger the reproductive activity of these termites, leading to swarming events. This is when winged termites, known as alates, leave their colonies to find new mates and establish new colonies.

Similarly, fall also sees swarming activity as conditions become favorable again for reproductive activities. During these times, environmental factors like warmth and moisture create optimal conditions for both mating and the establishment of new colonies.

In contrast, winter presents harsh conditions that do not support such activities, and summer may not consistently provide the ideal circumstances for swarming due to varying climatic conditions. Understanding the timing of termite activity is crucial for effective pest management and prevention strategies.
