Visible mud tubes running up the exterior foundation wall — Valencia, Valencian Community
Pencil-width mud tubes running vertically up a foundation wall are highway tunnels built by subterranean termites to travel safely from soil to wood. Even a single tube means an active or recently active colony is feeding on your home's framing. Breaking a tube open may reveal live workers inside. A pest-control technician inspects the full perimeter, probes accessible wood for hidden damage, identifies the species, and applies targeted treatment — typically a liquid termiticide barrier or bait-station system — then schedules follow-up monitoring to confirm the colony is eliminated.
