Quick answer: the signs to check first
If you only have one minute, check these three spots:
- Foundation and garage edges for thin mud tubes
- Window sills and door tracks for piles of clear wings
- Trim and baseboards for wood that looks bubbled or sounds hollow
Then do one simple thing: take photos before you clean, scrape, or paint.
Visual signs library (tubes, wings, frass, blistered wood)
Use the table below as your quick reference. One sign can be a hint. Two or more signs in the same area are a strong reason to get an inspection.
Visual sign table
| Visual sign | What it looks like | Where you might see it | What to do next |
|---|---|---|---|
| Mud tubes | Brown dirt-like lines, often pencil width | Foundation walls, slab edge, garage, utility lines | Photograph, avoid breaking it, call for an inspection |
| Discarded wings | Small piles of clear wings | Window sills, door tracks, near lights | Photograph first, then vacuum, save a few wings in a bag |
| Frass | Tiny pellet-like piles, sometimes near a small hole | Below wood trim, near frames, under eaves | Photograph the pile and the nearest wood surface |
| Blistered wood | Paint or wood that looks bubbled, swollen, or uneven | Baseboards, window trim, door frames | Note any nearby moisture and schedule an evaluation |
| Hollow-sounding wood | Wood that sounds papery when tapped | Trim, frames, porch posts, fascia | Do not poke hard, document, and get it checked |
If you are wondering which of these matter most, common termite warning signs include shelter tubes, swarms or wings, and evidence of tunneling in wood (UC IPM termite signs overview).
Mud tubes (the tiny tunnels that do not belong on your house)
Mud tubes can blend into concrete and soil. Texas A and M describes mud shelter tubes on foundations and slabs as a key sign used when inspecting for termite activity (Texas A&M termite guide).
Discarded wings (the cleanest mess termites leave behind)
Wings inside are worth taking seriously, especially when you find them near windows, doors, or light sources.
Frass (termite droppings) and what it can look like
Frass is often mistaken for sawdust or dirt. If you see a small pile that comes back after you clean it, take photos and book an inspection.
Blistered or bubbled wood (looks like water, sometimes is not)
Paint bubbles and swollen wood can come from moisture issues, but they also show up on termite warning lists. Virginia Tech Extension includes bubbling paint and hollow sounding wood among common signs homeowners are told to watch for (Virginia Tech Extension PDF).
False alarms Austin homeowners run into
Not every weird wood issue is termites. Here are the look alikes that cause the most confusion.
Flying ants vs termite swarmers
The fastest check is antennae, waist, and wings. The University of Maryland Extension explains that termites typically have straight antennae, a thicker waist, and wings that are similar in size, while flying ants have elbowed antennae and a pinched waist (University of Maryland Extension comparison).
Moisture damage and normal home movement
Austin homes can see humidity swings and shifting soil. Sticking doors or cracked caulk can come from everyday home changes, so it helps to look for a second sign like wings or tubes before you assume termites.
A homeowner checklist: Do I have termites
Answer these with yes or no:
- I see mud tubes on the foundation, garage wall, or slab edge
- I find wings inside near windows or doors
- I notice wood that looks bubbled or sounds hollow
- The same sign keeps showing up in the same spot
- I see more than one sign from the visual table
If you check two or more boxes, it is time to book an inspection.
What to document before you call
- Photos of the sign, plus a wider shot of the full wall
- A note about when you first noticed it
- Any nearby drips, leaks, or recent water events
When to call a pro in Austin
Call for help if any of these happen:
- Tubes on the foundation or inside the garage
- Wings indoors that appear more than once
- Soft or hollow trim in a high traffic spot
A professional inspection can confirm what you are seeing and help you decide the next step with confidence.
What not to do
- Do not paint over the area before it is checked
- Do not break tubes and assume the problem is gone
- Do not rely on random sprays for a hidden issue

FAQ (5 questions)
1) What is the number one termite sign homeowners miss?
Mud tubes are easy to overlook because they can blend into concrete and soil. If you see any tube like line along the foundation, it is worth checking sooner rather than later.
2) If I find wings inside, does that always mean I have termites?
Not always, but it is a strong reason to investigate. Photograph what you found, note the room and window, and schedule an inspection if it happens again.
3) Can water damage look like termites?
Yes. Bubbling paint and swollen trim can come from moisture problems. If you also see wings or tubes, get a professional opinion.
4) Should I clean up frass or wings before an inspection?
Photograph it first. After that, you can vacuum it, but saving a small sample in a bag can help with identification.
5) When should I stop guessing and call a pro?
If you see two or more signs from the library, or the same sign keeps returning in the same spot, it is time to call. A quick inspection is the fastest way to replace worry with a real answer.
