What is a Termite?
There are three main varieties of termites: subterranean, drywood, and dampwood. Subterranean termites live in the soil and are willing to tunnel dozens of meters just to find wood to feed on. Drywood termites are more commonly found in the southern United States and, like their namesake, prefer dry wood (unlike most of their kin). Finally, dampwood termites are larger and can only survive in moist, humid environments. They can live within wood and plug up holes to preserve moisture. This can make them difficult to notice.
Physically, these three varieties of termite look fairly similar. They have thick waists, straight antennae, and short legs. Their size is between 1/4 of an inch to about 3/8 of an inch, and their coloring varies in shade from light cream to darker black-brown depending on their role in the colony they live in.
