People often ask me when are termites active. They are active all year. Yes it is a fact that spring is the most active time. The swarmers come out in spring and in rare times right before fall. The swarmers are only looking to start a new colony. The swarmers will come out of differant areas in droves! The swarmers will try to find a mate and if they find the right soil conditions, start a new colony. The swarmers themselves do not do the damage to wood like the workers do. If a swarmer does not find a mate within a few days, they will drop their wings and then die within a few days.
