Termite Signs & Damage: How To Tell If You Really Have Termites
Use this checklist to separate true termite activity from normal wear, old repairs, or harmless insects. The goal: gather clear evidence so you can decide if you need a professional termite inspection.
Most Common Visible Signs of Termites
Termites are designed to stay hidden, but they leave very specific signs when they move between soil and wood, or when a colony sends out winged swarmers. Start with these:
- Mud tubes running up foundation walls, piers, or inside a crawlspace.
- Hollow or papery-sounding wood when you tap baseboards, door frames, or trim.
- Detached wings collected on windowsills, near doors, or in light fixtures.
- Soft, blistered, or bubbling paint with wood that feels weak underneath.
- Visible galleries (channels carved along the grain) when damaged wood is opened.
| Sign | Priority | What to do next |
|---|---|---|
| Mud tubes on foundation or piers | High | Take clear photos, don’t break all tubes at once, and contact a licensed termite professional. |
| Wings indoors (especially near windows/doors) | High | Save some wings in a bag, photograph close-up, and schedule an inspection. |
| Hollow-sounding baseboards or trim | Medium | Map all affected areas, note if there’s moisture history, then get a pro opinion. |
| Blistered paint, soft to the touch | Medium | Rule out plumbing leaks first; if none, consider termites or other wood-destroying insects. |
| “Saw dust” piles under wood | Low / varies | May be carpenter ants or beetles. Photograph in good light for species ID. |
What Looks Like Termites But Isn’t
Many homeowners get spooked by any insect near wood. A few common false alarms:
Ants vs termite swarmers
- Ants have a pinched “waist,” bent antennae, and wings of unequal length.
- Termites have a straighter, uniform body, straight antennae, and wings of equal length.
If you can, place a few insects or wings on white paper and take a close-up photo in good lighting. This can help a pro or extension office identify them quickly.
Water damage vs termite damage
- Water damage usually shows dark staining, swelling, or mold along with soft wood.
- Termite galleries follow the grain and often leave a thin outer shell that sounds hollow.
- Sometimes you’ll see both: a leak that attracted termites.
Photo Examples: What Termite Activity Actually Looks Like
These examples help you compare what you're seeing at home with typical termite evidence. You can use this list while taking your own pictures during a walk-through.
Mud Tubes (Subterranean Termites)
Look for brown, dirt-like tubes about the width of a pencil climbing foundation walls, piers, or crawlspace supports.
- Often appear in protected, shaded areas.
- Active tubes are moist inside; old tubes crumble easily.
Termite Wings vs Ant Wings
These are most commonly found on windowsills, counters, or near doorways after a swarm.
- Termite wings: equal length, pale, and more delicate.
- Ant wings: top wing longer than bottom wing.
Termite Galleries (Internal Wood Tunneling)
Galleries follow the grain of the wood and often have a thin, papery exterior left intact.
Blistered Paint / Hollow Wood
Even if the exterior looks intact, the wood beneath may be soft or hollow when tapped.
Drywood Frass (Pellet Droppings)
Drywood termites push out hexagon-shaped pellets that look like tiny piles of sand or pepper.
Where To Check: Room-by-Room & Outside
Do a slow walk-through of your home and lot. You’re not trying to become an expert—just to gather enough info for a clear conversation with a pro.
Indoors
- Baseboards, door frames, and window trim—especially on exterior walls.
- Rooms with moisture history: bathrooms, laundry, kitchens.
- Garage trim, door jambs, and any “soft spots” where cars bump or water splashes.
Outside perimeter
- Foundation walls for mud tubes or old treatment drill holes.
- Deck posts, porch columns, and wooden steps.
- Areas where soil or mulch touches siding—these should ideally have a small gap.
Crawlspace / basement (if you have one)
- Wooden sill plates on top of foundation walls.
- Support posts, beams, and joists—look for channels, mud, or previous repairs.
- Any areas that stay damp or have poor ventilation.
Checklist: Termites vs Ants
Use this quick side-by-side list when comparing insects or wings you’ve found indoors. You can literally walk through this checklist while looking at your photos.
- ☐ Body shape: Termites have straight bodies; ants have a pinched waist.
- ☐ Antennae: Termites have straight antennae; ants have bent antennae.
- ☐ Wings: Termite wings are equal length; ant wings are unequal.
- ☐ Color: Termite swarmers are usually tan to brown with pale wings.
- ☐ Wing piles: Termites often leave piles of wings; ants usually do not.
Checklist: Active Termite Damage vs Old / Inactive Damage
Old damage does not always mean an active infestation. This checklist helps you tell the difference and decide how urgent a professional inspection might be.
- ☐ Fresh mud: Tubes look moist or recently built ⇒ more likely active.
- ☐ Crumbling tubes: Dry, easily crumbled tubes ⇒ may be old or inactive.
- ☐ Hollow wood: Sounds papery when tapped ⇒ structural wood may still be compromised.
- ☐ New frass: Fresh pellet piles under trim ⇒ likely active drywood termites.
- ☐ Paint blisters: Soft under pressure with no obvious leak ⇒ could indicate recent activity.
- ☐ Recent wings: New wings indoors near doors/windows ⇒ a swarm occurred recently.
How to Take Clear Photos for a Termite Inspector
Good photos help professionals give accurate guidance before they even visit. Use this quick guide while you walk the house:
- Turn off the harsh flash — use natural light or your phone flashlight from the side.
- Get close (4–6 inches) but tap the screen to focus before taking the photo.
- Include a reference object (coin, key, tape measure) for scale in at least one photo.
- Take one wide photo showing the overall area (wall, window, foundation section).
- Take one close photo showing mud tubes, wings, frass, or galleries clearly.
- In crawlspaces use a strong LED flashlight and watch footing and clearance.
Helpful tools for your walk-through (affiliate)
You can do a basic check with nothing more than your phone flashlight. If you want to go a step further, many homeowners use simple inspection tools:
- A bright LED flashlight for crawlspaces, corners and rim joists.
- A moisture meter to double-check suspicious soft or damp areas.
- A clip-on macro lens to capture close-up photos to text or email to a pro.

When Should I Call a Termite Professional?
In general, it’s worth scheduling a professional termite inspection if:
- You see mud tubes, swarmers indoors, or clearly hollowed wood.
- You’re buying or selling a home and there’s any question about past activity.
- You know there’s a history of termites in the house or neighborhood.
If you’re unsure, err on the side of getting an inspection—especially if you’re in a high-pressure termite region. A reputable company will explain what they see and outline treatment or monitoring options.
