Termites don’t knock before they come in. They quietly chew through wood for months, sometimes years, and most homeowners only notice when a floorboard feels soft or a door suddenly sticks. The good news is that termites do leave clues. Learn these early warning signs and you’ll have a much better chance of catching these pests before the repair bill gets scary.
1. Swarmers or Discarded Wings
In spring or after warm rain, reproductive termites called swarmers leave the colony to start new ones. Finding small, equal-sized wings near windowsills, doors, or light fixtures is one of the clearest signs of termite activity.
2. Mud Tubes
Subterranean termites build pencil-width mud tubes to travel between the soil and wood while staying protected. Check your foundation, crawl space, basement walls, and around pipes.
3. Hollow-Sounding Wood
These pests eat wood from the inside out, often leaving a thin outer layer. Tap baseboards, window frames, and wooden beams. If they sound hollow or papery, investigate further.
4. Frass (Termite Droppings)
Drywood termites push out tiny pellets that look like sawdust or coffee grounds. Small piles near wooden furniture, trim, or walls can be a warning sign.
5. Bubbling or Peeling Paint
Paint that bubbles or blisters can be caused by moisture, but it can also be a sign of termites tunneling underneath.
6. Sticking Doors and Windows
Termite damage and the moisture they create can warp frames, making doors and windows harder to open.
7. Sagging Floors or Ceilings
In advanced cases, structural damage can cause floors to feel soft or ceilings to sag. This needs professional attention right away.
Termites vs. Flying Ants
| Feature | Termite Swarmer | Flying Ant |
|---|---|---|
| Waist | Thick, straight | Narrow, pinched |
| Antennae | Straight | Bent (elbowed) |
| Wings | Two pairs of equal length | Front wings longer than back wings |
What to Do If You Suspect Termites
- Don’t disturb the area. Breaking mud tubes or spraying can make these pests move elsewhere and harder to find.
- Take photos and collect a few wings or insects in a sealed bag if possible.
- Schedule a professional inspection. Many pest control companies offer inspections, and treatment options depend on the termite species and the extent of the problem.
- Get more than one quote and ask about warranties and follow-up inspections.
How to Prevent Termites
- Fix leaks and keep gutters and downspouts directing water away from the foundation.
- Reduce moisture in crawl spaces with ventilation or a vapor barrier.
- Keep firewood, lumber, and mulch away from the house.
- Avoid direct wood-to-soil contact for decks, fences, and siding.
- Schedule periodic termite inspections, especially in warm, humid regions.
Does Homeowners Insurance Cover Termite Damage?
In most cases, standard homeowners policies don’t cover termite damage because it’s considered preventable through maintenance. Check your policy to be sure.
Where to Look for Termites Around Your Home
Termites love moisture and wood, so focus your search where those two meet. Grab a flashlight and check these spots a couple of times a year:
- The foundation and exterior walls, especially near soil
- Crawl spaces and basements
- Around water heaters, sinks, and bathrooms
- Window frames, door frames, and baseboards
- Decks, fences, and wooden steps
- Firewood piles and tree stumps near the house
Types of Termites
- Subterranean termite colonies: live in the soil and build mud tubes to reach wood. They’re the most common type in many areas.
- Drywood termite colonies: live inside dry wood and leave small pellets (frass) behind.
- Dampwood termites: prefer wood with high moisture, such as decaying logs or leaky areas.
Knowing which type you have matters because the treatment for one kind of termite can be very different from another.
DIY vs. Professional Treatment for Termites
Store-bought products can help with small, isolated problems, but termites are hard to eliminate completely without professional tools. Pest control companies may use soil treatments, bait systems, or localized wood treatments. Ask any company you talk to about the treatment method, follow-up visits, and warranty. For unbiased information about pesticides and safety, the National Pesticide Information Center is a reliable resource.
Termites and Your Budget
Termite damage is usually not covered by standard insurance or a home warranty. Our guide to home warranty vs. homeowners insurance explains why. That’s one more reason regular inspections are worth it. And if you’re seeing small insects in the kitchen instead, it might just be ants. Here’s how to get rid of ants in the kitchen.
Termites FAQ
What time of year do termites swarm?
Many species swarm in spring, often on warm days after rain, but timing varies by species and region.
Can termites go away on their own?
Unfortunately, no. An established colony will keep feeding until it’s treated.
How often should I get a termite inspection?
Many experts suggest yearly inspections, especially in warm, humid climates or if your home has had these pests before.
Can I sell a house with termites?
Yes, but you’ll usually need to disclose it, and buyers may ask for treatment or repairs before closing.
A Simple Yearly Termites Checklist
- Walk the foundation and look for mud tubes.
- Tap wooden trim and baseboards for hollow sounds.
- Check window sills for discarded wings in spring.
- Look under sinks and around the water heater for moisture.
- Make sure gutters drain away from the house.
- Move firewood and wood scraps away from walls.
Doing this once a year takes less than an hour and helps you spot termites early, when treatment is simpler. If you find anything suspicious, take photos and call a professional for an inspection rather than trying to treat termites on your own.
Key Takeaways
- Discarded wings, mud tubes, and hollow-sounding wood are the clearest early signs of these pests.
- Moisture control is the best prevention.
- Do not disturb an active area; call a professional for an inspection.
- Standard insurance usually does not cover termite damage.
A yearly inspection and a dry, well-maintained home are your best defense against termites.
One More Tip
Can I prevent termites with home remedies?
Home remedies like orange oil or boric acid are sometimes used for small, localized drywood termite problems, but they are not reliable for established colonies. Prevention works better: fix leaks, keep wood away from soil, and schedule regular inspections. If you suspect termites, a professional inspection is the safest next step.
Final Thoughts
Discarded wings, mud tubes, and hollow-sounding wood are the most common signs of these pests. If you notice any of them, call a professional for an inspection and focus on moisture control to keep your home protected.
