Termites are active year-round, but their activity levels can vary depending on the species and environmental conditions. However, in most regions, termites tend to be more active during the spring and summer months. Warmer temperatures and increased moisture create favorable conditions for termite swarming, during which reproductive termites leave their colonies to establish new ones. Spring is often referred to as termite swarm season. However, it’s essential to remember that termites can cause damage at any time of the year, and infestations should be taken seriously regardless of the season.
