Florida has from one to four colonies for every acre of land. That's an averae of about four houses per acre. They build long, tunnels, or tubes, from soil mixed with their own feces to form a crude plaster that can sustain a termite freeway from the nest directly to the nearest piece of wood. These tubes have been found extending as far as 60 feet. So, they're serious about what they're doing.
Subterranean termites have a more varied diet than their cousins.
Being non-discriminating, they attack furniture, flooring, wall paneling and have a taste for some plastics. Because they are hidden, and evidence of their being on the premises is usually hidden, too, they can hang around for years munching on your home's structural timbers before you know they're there. They are responsible for 95 percent of all termite damage. In Florida, termites swarm in February, March and April. On the Funcoast, April is the big month.
