Termites are called "silent destroyers" for a reason—they chew through your home’s structure without a sound, often for years, before you notice. By the time visible damage appears, repairs can cost thousands. But what if you could spot them before it’s too late? Here are 9 sneaky signs most homeowners overlook—and what to do if you find them.
1. Hollow-Sounding Wood (The Knock Test)
Termites eat wood from the inside out, leaving a thin veneer. If your floors, walls, or furniture sound hollow when tapped, it’s a red flag. Try this:
- Tap baseboards, window sills, and door frames with a screwdriver handle.
- Listen for a papery or empty echo (healthy wood sounds solid).
2. Discarded Wings Near Windows
After swarming, termites shed their wings. Finding tiny, translucent wings on windowsills or in spiderwebs means a colony is nearby. Key details:
- Wings are all the same size (unlike ants, which have uneven wings).
- Often appear in spring/summer after rain.
3. Mud Tubes on Foundations
Subterranean termites build pencil-sized mud tubes to travel between soil and wood. Check these hidden spots:
- Crawl spaces
- Behind shrubbery near the foundation
- Basement corners
4. Frass (Termite Droppings)
Drywood termites push out tiny, wood-colored pellets called frass. Look for:
- Small piles resembling sawdust or coffee grounds.
- Often under attic beams or wooden furniture.
5. Stuck Windows or Doors
Warped frames from termite moisture can make doors/windows hard to open. Don’t blame humidity—check for:
- Bubbling paint (trapped moisture from termites).
- Cracks in frames (a sign of weakened wood).
6. Clicking Noises in Walls
Soldier termites bang their heads against wood to signal danger. At night, press your ear to walls—if you hear faint clicking, it’s time to investigate.
7. Sagging Floors or Ceilings
Advanced infestations compromise structural integrity. Warning signs:
- Floors that dip or feel spongy.
- Cracked ceiling paint (from shifting beams).
8. "Blisters" in Wood Floors
Termites tunneling under flooring can cause:
- Dark, raised spots resembling water damage.
- Peeling laminate (from moisture they create).
9. Mystery "Dirt" in Odd Places
Termites mix saliva and soil to build nests. If you find gritty dirt in non-dirty areas (like closets or cabinets), probe further.
What to Do If You Spot These Signs
Don’t panic—but act fast. Termites work 24/7, and DIY sprays rarely reach the colony’s core. Here’s your game plan:
- Document: Take photos of damage/frass/mud tubes.
- Call a pro: inspections can confirm the issue.
- Prevent spread: Reduce moisture (fix leaks, improve drainage).
Termite FAQs: Your Top Questions Answered
1. How fast do termites spread?
A colony of 60,000 termites can eat 1 foot of a 2x4 board in just 5-6 months. Left unchecked, they can cause major structural damage in 1-2 years.
2. Can I treat termites myself?
DIY solutions like sprays or foams only kill surface termites. The queen and colony often survive. Professional treatments (like termiticides or bait systems) are far more effective.
3. Are termites active in winter?
Yes! Subterranean termites tunnel deeper underground but stay active. Drywood termites remain active year-round inside your home's wood.
4. What’s the average cost to treat termites?
Prices range from $200–$2,500+ depending on:
- Infestation size
- Treatment type (spot vs. whole-house)
- Your location
5. How can I prevent termites naturally?
While no natural method is 100% effective, you can:
- Keep firewood and mulch away from your home’s foundation
- Fix leaky pipes and improve drainage
- Use termite-resistant wood (like cedar or redwood) for decks/fences
Final Thought: Don’t Wait for Obvious Damage
Termites cost U.S. homeowners $5 billion annually—often because early signs were ignored. If your gut says something’s off, trust it. A $100 inspection today could save you $10,000 in repairs tomorrow.
