Signs of Termites in a Lakeland, FL Home — The Nine Things to Look For

Do the 60-second walk before you do anything else

Look, here’s the deal. You don’t need to be an entomologist to get a very good idea of what’s going on. You need a flashlight, a flathead screwdriver, and about ten minutes. Do this now, because whatever you find will make the licensed operator’s job dramatically faster — and it’ll stop you from buying the wrong treatment.

Outside: walk the whole foundation slowly, at knee height, with the flashlight held low and raking across the surface. Then do the inside of the garage block wall — the most-ignored surface in any Lakeland house.

Inside: windowsills, door frames, baseboards, the underside of the kitchen sink, the wall behind the toilet, and the attic hatch. Tap the trim with the screwdriver handle as you go.

Now here’s what you might find, and what it means.

The nine signs, and what each one is telling you

1. Mud tubes on the block, slab or pier

If you find one thing on this page, this is the one. A raised line of dried mud about the width of a pencil, running up concrete block, the slab edge, a pier, a plumbing stack, or across the inside of the garage wall.

What it means: subterranean termites, definitively. They live in the soil and cannot survive exposed to open air, so they build these covered highways to reach your wood. A tube is a commute in progress.

The test: break out a half-inch section with the screwdriver. Cream-coloured soft-bodied insects inside means active right now. No insects, but the gap sealed back up with fresh mud when you check in a few days — also active; they repaired the road. Dry, empty, and still broken open a week later usually means old activity, which is not a green light: whatever let them in is probably still there.

Don’t knock them all down. Intact tubes are a map that tells the inspector where the colony is coming from. Break one, leave the rest.

2. Little piles of hard pellets (frass)

Small heaps of what looks like coarse sand, sawdust or coffee grounds — classically on a windowsill, a bookshelf, the garage floor, or the top of a baseboard.

What it means: drywood termites. Get close, or zoom in with your phone. Drywood frass is hard, uniform, about a millimetre long, and six-sided with slightly concave faces. That geometry is the identification. Sawdust is fibrous and irregular; frass is granular and hard. Colour tells you nothing — it takes on the shade of whatever wood they’re eating, from pale tan to nearly black.

The test: sweep it up. If it’s back in a few days, the colony is active. And look directly above the pile for a pinhead-sized round kick-out hole — frass falls straight down, so the pile points at the source.

3. Discarded wings on a sill or in a light fixture

A little scatter of translucent wings, often in a windowsill, a spider web, a bathtub, or around a light. All four wings the same size, roughly twice the length of the body.

What it means: a swarm happened. Termite swarmers drop their wings almost immediately after flying — they only need them once. Wings inside your house are one of the most under-rated signs there is, because a swarm coming out of your structure means a colony that’s mature enough to reproduce, which takes years.

The test: note the month. February to May in daylight, after warm rain, points at eastern subterranean. Late spring on humid evenings, around lights, suggests Formosan. May to August on warm evenings points at drywood. The Polk County swarm calendar has the full breakdown.

4. Swarmers themselves — and how to tell them from flying ants

This trips up almost everyone, and it matters, because flying ants are a completely different problem. Here’s the three-second version.

If it’s ants, you want ant control in Lakeland instead. If it’s termites, keep reading — and try to capture two or three specimens in a jar or a piece of tape. A real specimen makes the operator’s identification faster and firmer than any description you can give over the phone.

5. Wood that sounds hollow when you tap it

Run the handle of the screwdriver along baseboards, door frames, window frames, and any exposed structural timber. Solid wood gives a dull thud. Compromised wood gives a papery, drum-like knock.

What it means: termites eat the inside and leave the outer skin and the paint film intact. That’s exactly why a board can be structurally worthless and still look fine from three feet away. A hollow knock is one of the earliest signals available to you, and it costs nothing.

6. Blistered, rippled or sunken paint

Paint that bubbles, wrinkles or dips in a way that looks a bit like water damage — but there’s no leak anywhere near it.

What it means: the wood behind the paint film has been eaten out, and the film is all that’s left holding the shape. Common on window frames, door casings and baseboards. Press it gently — if it gives, there’s nothing behind it. Distinguishing this from genuine water damage matters, and the damage-identification guide covers exactly how to tell them apart.

7. Doors and windows that suddenly stick

A door that used to close cleanly and now catches. A window that’s become hard to open.

What it means: maybe nothing — Polk County humidity swells wood, and this is a genuinely common false alarm in the summer. But it can also mean termite galleries have weakened the frame and it’s shifting. The tell-tale: humidity affects everything at once and eases off when the weather changes; a termite-weakened frame sticks and stays stuck, and usually just one or two do it. Combine this sign with any other on the list and it becomes a lot more meaningful.

8. Floors that sag, buckle or feel spongy

Laminate lifting at a seam, tile cracking in a line, a floorboard with give in it, a soft spot near an exterior wall or a bathroom.

What it means: potentially a long-running subterranean infestation in the subfloor or the sill. This is a late-stage sign, not an early one, and it’s the one that should move you to act quickly — not because the house is going to fall down this week, but because damage this visible means years of quiet feeding.

9. Live termites in the wood itself

You pry back a piece of soft trim, or lift a board, and there they are: pale, soft, roughly rice-grain sized, moving away from the light immediately.

What it means: exactly what it looks like. Take a photo, take a specimen if you can, put the board back, and stop excavating — disturbing a subterranean colony can push it to relocate deeper into the structure, which makes it harder for the operator to find and treat.

How the Lakeland dispatch line gets you to a licensed operator

Match your sign to the termite — because the treatment follows the species

Once you know the species, the complete Lakeland termite treatment guide walks through what each treatment actually involves, and the termite control hub covers every service available locally.

Where to look, specifically, in a Polk County house

Termites go where it’s damp and where there’s a way in. In Lakeland, that means a handful of very predictable places.

• The bath trap. The void in the slab beneath the tub or shower where the plumbing comes through — often bare soil, dark, damp, and opening straight into your wall cavity. The most common hidden entry point in Florida slab construction.
• The garage block wall, from the inside. Nobody looks. Tubes turn up there constantly.
• Under the kitchen sink and behind the toilet. Any chronically damp cabinet base or wall.
• The attic hatch and the gable vents. Drywood swarmers get in through torn or missing vent screening. Look for frass on the joists and on top of the ceiling insulation.
• Fascia, soffit and exposed rafter tails. Especially on the older Dixieland, Garden District and Cleveland Heights bungalows, where there’s a lot of original decorative woodwork.
• Wherever the sprinkler hits the wall. Common in the newer South Lakeland, Christina, Grasslands and Highland City builds — irrigation aimed at stucco five mornings a week keeps the foundation permanently damp.
• Anywhere wood touches soil. Fence posts fixed to the house, deck supports, the firewood stack against the garage, wooden trellises. Direct road in.

And a note on age. Pre-1990s slabs — a lot of the housing stock around Lake Morton and Lake Hollingsworth — have had decades to settle and open hairline cracks at plumbing penetrations and expansion joints. A termite needs a gap about the width of a business card. Newer construction has better pre-treatment but usually more irrigation and denser foundation plantings. Different era, same physics.

What to do — and not do — before the operator arrives

• Do photograph everything, with something for scale in the shot — a coin, a pen. Photos of tubes, frass, wings and damage give the inspector a head start.
• Do collect specimens if you can. A few swarmers in a jar or stuck to a piece of tape beats any verbal description.
• Do note the date and time you saw a swarm, and whether it was day or evening. That single detail often identifies the species on its own.
• Don’t knock down every mud tube. They’re the map.
• Don’t spray it with a hardware-store aerosol. With subterranean termites, repellent products can push the colony to route around the treated area and deeper into the structure, which makes the professional treatment harder and the infestation more expensive to solve.
• Don’t start demolishing trim to see how bad it is. You’ll disturb the colony and destroy evidence. Let the inspection happen first.

If you’re in the middle of a real-estate transaction, what you actually need is the formal, documented version of all of this — see WDO inspections in Lakeland.
