During which months do drywood termites typically swarm in Southern California?

The correct answer identifies September and October as the key months for drywood termite swarming in Southern California. This timing aligns with the typical life cycle and environmental conditions preferred by these pests.

During late summer and early fall, the temperature and humidity conditions tend to be ideal for drywood termites to emerge from their colonies to mate and establish new colonies. Specifically, the swarming period often coincides with warm evenings, which provides a suitable environment for these termites to take flight in search of new habitats.

Other months don't usually align with the conditions necessary for significant termite activity. For instance, June and July may be too early, as the termites typically haven't reached the point where their populations are ready to swarm. Similarly, swarming in the winter months like October and November is less common due to cooler temperatures, which are unfavorable for this activity. Thus, September and October are recognized as peak months for drywood termite swarming in this region, making this answer the most accurate.
