Early Warning Signs of Termites Every Homeowner Should Know

Termites are the quietest expensive problem a house can have. They feed on wood from the inside out, often for months or years before anyone notices, which is why learning the early signs is one of the more valuable things a homeowner can do.

The clues to look for

• Mud tubes. Pencil-width tunnels of dried mud running up a foundation wall, pier, or crawlspace are a classic sign of subterranean termites traveling between the soil and your wood.
• Discarded wings. After termites swarm, they shed their wings. Small piles of identical, translucent wings near windowsills or doors are a red flag.
• Hollow-sounding wood. Tap on trim or framing — if it sounds papery or hollow, termites may have eaten it out from within.
• Bubbling or uneven paint, or wood that looks blistered, can hide damage underneath.
• Frass — tiny, gritty pellets that look like sawdust or coffee grounds — left by drywood termites near the wood they are eating.

Why moving fast matters

A mature termite colony can number in the hundreds of thousands and cause thousands of dollars in structural damage that most homeowners insurance policies will not cover. The longer they work undetected, the bigger the repair bill. Damage to load-bearing framing is not just costly — it can become a safety issue.

Do not try to treat it yourself

Store-bought sprays reach the termites you can see and miss the colony you cannot, which lets the real problem continue behind the walls. Effective termite control means locating the colony and treating the whole structure, which takes professional equipment and know-how. If you spot any of these signs, get a professional inspection promptly. In and around Phoenix, the specialists we suggest for termite inspection and treatment can confirm what you are dealing with and lay out the options.

Stay ahead of it

Keep soil and mulch from piling against wood siding, fix leaks that keep wood damp, and schedule a periodic inspection — the earlier termites are found, the smaller the problem stays.
