Termite season does not have a fixed start or end because termites are active year-round; however, they are most visible and active during warmer months, roughly from March to November, which coincides with the Major League Baseball season
. In warmer climates, termites remain active throughout the year, while in cooler climates, their activity slows down during the winter months (November to February) but they can still cause damage
. The prime termite swarming season, when termites are most noticeable due to swarms of winged reproductives, generally occurs in spring and summer. Most subterranean termites swarm during these months, typically on warm, calm days after rainfall
. Some species, like drywood termites and certain subterranean termites (e.g., R. hageni), may swarm later, from late summer to fall (August through November)
. Swarming events usually last 30 to 40 minutes on a warm day, but the overall termite season with visible activity can span several months depending on the species and local climate
. For example, eastern subterranean termites’ season can last about 5-6 months starting near the end of winter
. In summary, termite season typically lasts from early spring through late fall (about 5-9 months), with peak swarming activity in spring and summer, but termites remain active and potentially damaging year-round depending on climate and species
