Termites, ants, beetles, bees, and fungi are wood-destroying organisms, which can do massive damage to a home. Termites alone cause more property damage annually than fires, floods, or earthquakes combined.
Termites: Mud tubes on or in wooden structures such as floor joists, sill plates, wall studs and rafters.
Powder post beetles: They are often found in damp crawl spaces, old damp basements and in barns.
Carpenter ants: Coarse sawdust (frass) coming from behind siding, along sill plates, around window and door frames, and in attics. Insect parts in the frass is a sign of carpenter ant activity.
Carpenter bees: Routinely chew round, half-inch holes into wooden fascia boards, window and door frames, and even into treated deck wood.
