Most homeowners in Florida don’t find out they have termites until something doesn’t make sense. A door that worked fine last month won’t close all the way. Paint bubbles on a wall nowhere near any plumbing. None of it seems connected until someone opens up a wall.
Catching it early is the whole game. The difference between a manageable treatment and a full rebuild comes down to how long the colony had before anyone called.
Signs of Termites in Your Walls
Termites aren’t subtle once you know their tells. Most of the activity stays hidden inside wall cavities, where a colony can feed for months before it surfaces anywhere you’d notice. Florida’s heat and humidity make that window shorter than most homeowners realize. Formosan subterranean termites especially. They can move through structural wood at a pace that catches people completely off guard.
A few things worth checking if you suspect activity:
- Paint that bubbles or peels with no water leak anywhere nearby
- Hollow sounds when you knock on sections of wall that should be solid
- Visible termite tubes along your foundation or baseboards, mud-colored and usually about a quarter-inch wide
- Wood that feels soft or gives slightly under pressure in spots that shouldn’t
- Frass collecting near baseboards or windowsills: tiny, wood-colored pellets the colony pushes out as it feeds
That frass matters because it’s not a historical sign. When drywood termites push pellets out, the colony is feeding right then. They’re common throughout Florida, and that’s current output, not residue from something that already passed.
Termite Holes and Small Openings in Drywall
The holes are smaller than most people expect. Sometimes no wider than a pinhead, showing up in clusters that look like someone pressed a sharp object into the same spot over and over. They don’t tear or splinter. Just clean, shallow openings that are easy to write off as nothing.
Drywall signs of termites go beyond holes themselves. Watch for surface blistering and maze-like patterns beneath the paint. Sections of drywall that crumble or dent more easily than expected are also worth taking seriously.
Subterranean termites in Florida sometimes line their galleries inside drywall with mud. Open up a damaged section and you’ll see it. It’s the same material they use in their shelter tubes, and finding it inside a wall confirms you’re not dealing with something minor.
Can You Hear Termites Inside Your Walls?
It sounds unlikely, but yes. Press your ear to the right section of wall in a quiet house and you’ll catch it: faint, dry tapping. Something like a fingernail dragged lightly across paper. That’s soldier termites. They knock their heads against the wood to signal the rest of the colony when they sense a threat.
Most people only pick it up when they’re actively listening for it. If you’re hearing it without trying, the colony is large. At that point, the feeding has been going on long enough that waiting around to confirm it isn’t worth the risk.
What Does Termite Damage Look Like Behind Your Walls?
Opening up a wall with termite damage is rarely what homeowners picture. From the outside you see a soft spot, or paint doing something it shouldn’t. Behind it, the wood has been eaten out in channels following the grain. The outer shell looks fine. Press on it and the whole thing gives. Structural studs can be reduced to a fragile lattice held together by mud and frass.
It rarely announces itself all at once. A soft section or a discolored paint spot shows up first. Weeks later, a nearby door starts sticking because the frame has shifted slightly. Eventually a baseboard pulls away from the wall on its own, and by then the damage has been accumulating for a while.
Each of those is the structure adjusting to wood that’s no longer carrying the load it should.
None of this is helped by Florida’s humidity. Wet wood feeds faster, and subterranean termites do well in the kind of moisture that’s just part of the air here. The gap between an early sign and real structural damage is shorter in this state than most homeowners expect. If something seems off, scheduling a termite inspection before you’re certain is the smarter move.
How to Get Rid of Termites in Your Walls
Species matters here. Drywood and subterranean termites don’t respond to the same treatments, and using the wrong approach wastes time while the colony keeps feeding.
Drywood termites live entirely inside the wood, so localized treatment or fumigation can reach them depending on how far things have spread. Subterranean termites are a different problem. Their colony is underground. The workers you’re seeing in the walls are foragers traveling up through shelter tubes, and treating the wall alone won’t touch the source.
Natural options come up a lot. Orange oil and borate-based products can knock back a localized drywood infestation, but a subterranean colony or anything widespread is outside what those products can handle on their own.
A licensed inspector will look at the species and where the colony is before recommending anything. For subterranean infestations, that’s usually a liquid termiticide barrier, a baiting system, or both. In Florida, it’s not unusual for more than one species to be active in the same structure. Treating the wrong one first is how a contained situation turns into a much larger repair project.
