Termites are capable of infesting any wood source, especially if it has contact with the soil. Most homes are built primarily with wood, which is why termites find your property so appealing. Inside, this means your walls, support beams, drywood, ceilings, floor boards, baseboards, windows, and insulation. In your backyard, termites can infest piles of firewood, roof tiles, patio furniture, decaying logs, and more.
