Termites are among the most destructive pests a homeowner can face — and among the hardest to spot. They feed silently, often for months or years, before the damage becomes obvious. Warm temperatures, moisture, and humidity drive termite activity, and while many colonies swarm in spring, they can swarm in fall too where it stays mild. Catching an infestation early — or spotting the warning signs before it takes hold — is the difference between a routine treatment and a major repair bill. Here are six signs to watch for.
1. Frass (Termite Droppings)
Frass is a telltale sign of drywood termites. As they tunnel and eat, they push their droppings out of the galleries, leaving small mounds of pellets. The pellets are tiny — about a millimeter long — and look like sawdust or fine wood shavings. You can find frass anywhere there's wood, including attics. If you spot it, schedule a termite inspection.
2. Discarded Wings
This is frequently the first — and sometimes only — visible sign. When a colony matures, winged termites leave to start new colonies, then shed their wings once they've landed. Because termites are drawn to light, you'll often find small piles of identical, translucent wings on windowsills or caught in spider webs. Wings inside your home mean it's time to call a professional right away.
3. Termite-Damaged Trees Nearby
Termites in a tree on your property can signal they're heading toward your home. Look for small holes and wood shavings where they've entered, especially near the base of the tree. Digging just below the soil line around the roots may reveal discarded wings or dead termites — a sign a colony is active close by.
4. Tight-Fitting Doors or Windows
As subterranean termites eat, their moisture and "mud" become trapped in the wood, causing it to swell. That swelling can make doors and windows suddenly hard to open or close. Humidity alone can cause this, but paired with other signs it's worth investigating.
5. Hollow-Sounding or Damaged Wood
Termites eat wood from the inside out, leaving a thin surface layer intact. Structural wood that sounds hollow or papery when tapped is a classic indicator, and you may also notice blistered or sagging wood. Any hollow-sounding wood should be checked before the damage spreads further.
6. Uneven or Bubbling Paint
Paint that bubbles, blisters, or looks uneven often signals moisture buildup underneath — which can mean water damage or termites. Since termites introduce moisture as they tunnel, bubbling paint is worth ruling out with an inspection.
What to Do If You Spot the Signs
Termites hide well, so the surest way to confirm activity is a professional inspection. Vinx Pest Control specializes in detecting termites — even when there are no visible signs — using moisture sensors, heat sensors, and sound-detection tools, then builds a targeted treatment plan to protect your home.
Frequently Asked Questions
Frass is termite droppings — tiny pellets about a millimeter long that look like sawdust or coarse wood shavings. Drywood termites push it out of their galleries, so you'll find small mounds beneath infested wood, along baseboards, or in attics. It's a strong sign of an active infestation.
When a colony matures, winged swarmers leave to start new colonies and shed their wings after landing. Small piles of identical translucent wings — often on windowsills or in spider webs, since termites are drawn to light — are frequently the first visible sign. Call a professional promptly.
As subterranean termites tunnel, the moisture and "mud" they introduce swells the wood, making doors and windows fit tightly. Humidity can do this too, but combined with other signs it's a red flag worth inspecting.
Often, yes. Termites eat wood from the inside out, leaving a thin shell, so wood that sounds hollow or papery when tapped is a classic warning sign — sometimes with blistered or sagging areas. Have it inspected before the damage spreads.
Because termites hide inside wood and underground, a professional inspection is the reliable way to confirm activity. Vinx uses moisture, heat, and sound-detection tools to find termites even without visible signs, then recommends a targeted treatment plan.
