6 Signs You Have a Termite Problem in Your Florida Home

Learn the 6 clear signs of termites in Florida homes, from mud tubes and frass to shed wings, plus what to do next before damage spreads.

6 Signs You Have a Termite Problem in Your Florida Home

If you own a home in Florida, termites are not a maybe. They are a when. Our warmth and humidity give these insects a year-round buffet, and by the time most homeowners notice something is wrong, the colony has often been feeding for months or longer. Learning the early signs of termites is the single best thing you can do to protect your biggest investment.

The tricky part is that termites work quietly and out of sight. They eat wood from the inside out, so the surface can look perfectly fine while the structure behind it turns to paper. Below are six clear signs of termites that Florida homeowners run into most often. Walk through them slowly, because catching just one of these early can save you thousands.

1. Mud Tubes Running Up Your Foundation

Subterranean termites, the most common and destructive type in Florida, build pencil-width tunnels made of soil, saliva, and wood. These mud tubes let them travel from the moist ground up into your home without drying out in the open air.

Look along your foundation, slab edges, crawl space piers, and the inside of your garage where the wall meets the floor. The tubes are usually tan or brown and about the width of a drinking straw. If you break a section open and see pale insects moving inside, you have an active colony working right now.

Even empty tubes matter. They tell you termites have been active, and abandoned tubes often mean the colony simply moved to another entry point rather than left.

2. Discarded Wings Near Windows and Doors

Every spring and into the wet summer months, mature colonies send out swarmers, the winged reproductive termites whose only job is to fly off and start new colonies. In Florida this swarm season runs heavy from roughly February through June, though our climate lets some species swarm nearly year-round.

After a swarm, these insects shed their wings almost immediately. You will find little piles of identical, translucent wings on windowsills, near sliding glass doors, in spider webs, or collecting on the floor beneath a light.

This is one of the most overlooked signs of termites because people assume the wings came from flying ants outside. If you find a scatter of matching wings indoors, treat it as a red flag that a colony is either inside your home or very close to it.

3. Frass and Tiny Pellets From Drywood Termites

Florida has a second major threat that does not need soil contact at all. Drywood termites live entirely inside the wood they eat, which means they often set up in attics, door frames, window sills, wood furniture, and roof beams.

Their calling card is frass, which is drywood termite droppings. Frass looks like tiny six-sided pellets, almost like coarse sawdust or coffee grounds, and it is often light tan to dark brown depending on the wood they are eating.

You will usually find small mounds of these pellets on windowsills, along baseboards, or on the floor directly below a piece of infested wood. The termites push the waste out through small kick-out holes, so a fresh pile that keeps reappearing after you sweep it up is a strong sign of an active infestation overhead.

4. Hollow or Papery Sounding Wood

Because termites eat wood from the inside, the damage stays hidden until you go looking for it. A simple test is to tap or knock on wood trim, door frames, baseboards, and structural beams with the handle of a screwdriver.

Healthy wood sounds solid. Infested wood sounds hollow, dull, or papery. In worse cases you can push the screwdriver right through the surface into a maze of empty channels running with the grain.

Pay attention to any wood that feels lighter than it should, crumbles easily, or has a thin blistered surface that looks almost like water damage. That blistered, wavy look on painted trim or door casings is a classic sign of termites feeding just beneath the paint.

5. Doors and Windows That Suddenly Stick

Florida humidity already makes wood swell, so this one gets dismissed constantly. But when termites tunnel through door frames and window casings, they introduce moisture and warp the wood as they hollow it out.

The result is doors and windows that suddenly become hard to open or close, or that no longer sit square in their frames. If a door that worked fine last year is now sticking and you also notice any of the other signs on this list, do not chalk it up to the weather alone.

The same goes for floors that feel spongy, ceilings that sag slightly, or baseboards pulling away from the wall. These can all point to termites quietly compromising the wood behind the scenes.

6. Bubbling Paint, Buckling Floors, and Visible Damage

By the time damage is obvious to the naked eye, the infestation is usually well established. Still, plenty of Florida homeowners first discover their problem through visible clues rather than the termites themselves.

Watch for paint that bubbles or peels in odd patches, walls with small pinholes, laminate or hardwood floors that begin to buckle, and trim that looks like it is being eaten from behind. Maze-like grooves in exposed wood, sometimes packed with dried mud, are another giveaway of subterranean activity.

None of these should be ignored. When the wood itself is visibly failing, the clock is no longer ticking quietly.

What To Do Next

Termites move faster than most people expect, and Florida gives them ideal conditions all year. If you spotted even one item on this list, the smart move is to get a professional inspection before you assume the worst or waste money on hardware-store sprays that only reach the surface.

A licensed inspector can tell you whether you are dealing with subterranean or drywood termites, how far the damage has spread, and what treatment actually fits your home. Working with a local pest control company that knows Florida's specific termite pressure is worth far more than a generic national quote.

Here is the practical takeaway. Walk your foundation, windowsills, and door frames once every few months. Keep an eye out for mud tubes, shed wings, and pellet-like frass, and tap on any wood that looks off. Termites are almost impossible to stop once they are established, but they are very beatable when you catch them early. A short inspection today beats a structural repair bill later.
