In North Georgia, usually around mid March early April, is when most termite swarmers appear. After a spring rain, and when the temp is around 70's when you can see winged termites. The swarmers are kings and queens who pair up and start new colonies. This is a natural thing in nature. If you see swarmers, the colony under your home has been there for a while.
Termites swarm only in large colonies.
