Termites are social insects that live in colonies and feed on cellulose-rich materials, primarily wood. They are divided into different castes, including workers, soldiers, and reproductive individuals (alates or swarmers). Termites have soft, pale bodies and straight antennae. One distinctive feature of termites is their tendency to build mud tubes or tunnels, which they use for shelter and transportation between their underground nests and food sources. Look for mud tubes along foundation walls, wooden structures, and in crawl spaces. Termites can cause extensive damage to homes and buildings if left untreated.
