Termites cause great economic damage because of their special ability to digest wood. There are three kinds of termites: subterranean, dampwood, and drywood, with subterranean termites being the most common. This group maintain colonies within the ground and builds mud tubes over rocks and cement foundations to bridge the gap between soil and wood. Dampwood termites do not require contact with the ground but do require wood or soil with a high moisture content. Drywood termites do not require contact with the ground and do not build mud tubes.
Discourage infestations by keeping the area under and around the house free of wood debris above and below the ground. Stack firewood away from the house and keep it off the ground. If the soil around the home''s foundation remains moist due to faulty plumbing or improper grade, repair the plumbing and alter the grade, since termites prefer moist soil.
