The impossible claim
Termites cost US homeowners up to $5 billion a year — and these three signs tell you they’re in your walls before the damage is done.
The verified facts
Three signs extension entomologists check first — in order:
- Mud tubes — pencil-thick shelter tunnels of soil and saliva climbing foundation walls. Subterranean termites build them to travel between soil and wood while keeping moisture in. Break one open: moist and dark inside = active colony; dry and abandoned = old trail
- Piles of discarded wings — on window sills, door frames, or spider webs. Reproductive swarmers fly out to mate, land, then deliberately snap off all four wings and start a new colony
- Hollow-sounding wood — tap baseboards and joists. Termites eat wood from the inside out, leaving the paint and surface intact; solid wood knocks, eaten wood echoes
Swarmer vs flying ant: broad waist + four equal-length wings + straight beaded antennae = termite. Pinched waist + two wing pairs of unequal length + elbowed antennae = ant.
Termites cost US homeowners up to $5 billion per year — and most infestations go unnoticed for years because the damage happens inside the wood.
