Termites

Termite identification and control

Termites cause more structural wood damage in the United States than fire, in the sense that the damage is slow, quiet, and often discovered at sale. Subterranean colonies live in soil. Drywood colonies live inside the timber. Formosan termites in the Gulf South are a different scale of problem. A can of spray from a hardware aisle does not treat a colony.

Start with drywood vs subterranean vs dampwood if you have pellets, tubes, or wet wood and do not know which invoice you are about to pay. Licensed inspection is the adult move. These pages exist so you can recognize evidence, stop making the site wetter, and know what a liquid barrier, baiting system, or fumigation is actually for.
