How to Tell If You Have Termites Before They Cost You Thousands

Termites do not announce themselves. By the time most homeowners notice a problem, the colony has often been feeding for months or even years. The good news: if you know what to look for, you can catch termites early and avoid the kind of structural damage that runs into the thousands. Here is how to read the signs, understand what you are dealing with, and know when it is time to call a professional.

The Warning Signs Most People Miss

Termites are quiet, but they leave clues. These are the ones worth checking for a few times a year:

• Mud tubes. Pencil-width tunnels of dried mud running up your foundation or crawl space walls. Subterranean termites build these to travel between the soil and your home without drying out.
• Discarded wings. Small piles of identical wings near windowsills or doors, usually in spring, mean a colony nearby sent out swarmers to start new colonies.
• Hollow or sagging wood. Tap suspect trim or baseboards. If it sounds papery or hollow, termites may have eaten the inside out while leaving a thin shell.
• What looks like sawdust. Drywood termites push out tiny six-sided pellets called frass that pile up beneath the wood they are eating.
• Bubbling or uneven paint. Often mistaken for water damage, this can signal termite activity just under the surface.
• Doors and windows that suddenly stick. As termites damage wood, the moisture and warping they cause can throw off the fit of frames.

Know What You Are Dealing With: Subterranean vs. Drywood

Not all termites behave the same way, and the type matters for treatment.

• Subterranean termites nest in the soil and enter your home through the foundation, often through those telltale mud tubes. They are the most common and the most destructive across most of the country.
• Drywood termites live inside the wood itself, with no soil contact required. They are the ones that leave behind frass pellets and tend to show up in attics, trim, and furniture.

You do not need to diagnose the species yourself. That is part of what an inspection is for. But knowing the difference helps you understand why a one-size-fits-all store product rarely solves the problem.

Why Waiting Is the Expensive Choice

Termites cause billions of dollars in property damage every year, and standard homeowners insurance almost never covers it because the damage is considered preventable. The longer a colony feeds, the more wood it destroys and the bigger the repair bill. Catching it early is the difference between a treatment plan and a contractor rebuilding part of your home.

Can You Handle Termites Yourself?

Spot-treating a single piece of visible wood with a store-bought product might kill the termites you can see, but it does nothing to the colony that is still active behind your walls or under your foundation. Subterranean colonies can contain hundreds of thousands of termites, and they will simply keep working from where you cannot reach. Effective termite control means treating the source, not the symptom, which is why this is one pest where professional treatment pays for itself.

What a Professional Inspection Actually Finds

Many infestations show no obvious signs at all, which is why a professional inspection is the only way to know for sure. A BRD technician checks your foundation, crawl space, attic, and wood structures for active termites and the conditions that attract them, then matches a treatment to the species and severity. From there it is targeted liquid treatments, bait stations, or other methods designed to eliminate the colony and protect your home long term.
