Subterranean termites do more damage to a home in a short time than other types of termites. They can demolish a foot of 2-inch lumber in less than four months. Subterranean termites can enter a home from the soil around a foundation, slipping in through cracks in concrete or onto wood. They create mud tubes from the nest to food sources such as wood beams and the paper components of walls. As they destroy a home’s wood supports from the ground up, an infestation needs to be treated as soon as possible in order to preserve the building from substantial damage.
