Subterranean termites are treated using the methods and procedures listed on the product label. Drywood termites are commonly treated using fumigation, wood removal or borate products for spot applications. When fumigation is performed, a certified applicator for the pest company must be present at the time the gas is released into the house and when the house is released for occupancy following the fumigation and proper aeration. A technician licensed to do termite work with the advice of a certified applicator can perform a treatment for Subterranean termites without the Certified Applicator being present. All termites subsist on cellulose, which termites get from wood.
Termites are social insects with a highly organized caste system, much like ants or bees.
Subterranean termites usually live outside the house in underground nests. Subterranean termites use moisture in the earth to survive. Since subterranean termites also need cellulose, they often tunnel into nearby homes to get it. Drywood termites, on the other hand, need no contact with the earth. Drywood termites live right inside the homes that they devour.
