Termites cause billions of dollars in property damage annually across the United States, with Florida homes being particularly vulnerable due to our warm, humid climate. In North Port, where subterranean termites thrive year-round, detecting an infestation early can save homeowners thousands in repair costs. Unfortunately, termites often work silently behind walls, floors, and foundations, making them challenging to detect until significant damage has occurred.

At F2 Exterminators, we’ve helped countless North Port residents identify and address termite problems before they become catastrophic. Here are the top five signs that could indicate termites have made themselves at home in your property.

1. Mud Tubes on Exterior Walls

Subterranean termites build protective tunnels, commonly called mud tubes, to travel between their colony in the soil and their food source—your home. These pencil-width structures are made from soil, wood particles, and termite saliva, creating a safe passage that shields termites from predators and prevents dehydration.

Where to look: Inspect your home’s foundation, crawl spaces, and any concrete or masonry surfaces that connect to the ground. Pay special attention to areas where soil meets your foundation and around utility entry points. These mud tubes can appear on both the exterior and interior foundation walls and may run vertically or horizontally.

What to do if found: If you discover what appears to be a mud tube, break off a small section. If it’s an active termite tunnel, you may see termites inside, or you might notice the tube being repaired within a few days. Either scenario confirms an active infestation requiring professional treatment.

2. Swarmers and Discarded Wings

When termite colonies mature, they produce winged reproductive termites called swarmers (or alates) that emerge to establish new colonies. In North Port, termite swarming season typically peaks in spring, though our warm climate can support multiple swarms throughout the year.

Where to look: Swarmers are attracted to light, so check windowsills, light fixtures, and doorways for clusters of winged insects or discarded wings. Termite swarmers are often mistaken for flying ants, but they have straight antennae, uniform waist, and equal-length wings—unlike ants with their bent antennae, pinched waists, and uneven wings.

What to do if found: The presence of swarmers or discarded wings indoors almost always indicates an established colony within or near your home. Even finding them outdoors within close proximity to your house warrants a professional inspection.

3. Hollow-Sounding or Damaged Wood

Termites consume wood from the inside out, leaving a thin veneer of surface wood intact as they hollow out the interior. This feeding pattern creates wood that sounds hollow when tapped and may appear blistered or darkened.

Where to look: Test wooden structures throughout your home by tapping them with a screwdriver handle, particularly baseboards, window frames, and door frames. Pay attention to any wood that sounds hollow or different from surrounding areas. Also, watch for wood that seems crushed at structural bearing points—a sign that termites have compromised its integrity.

What to do if found: If you suspect termite damage, gently probe the area with a screwdriver. Wood damaged by termites will often feel soft and may break easily, revealing tunnels or galleries within. This type of damage requires immediate professional evaluation.

4. Frass (Termite Droppings)

While subterranean termites typically don’t leave visible frass like their drywood counterparts, finding small pellet-like droppings near wooden structures can still indicate an infestation, particularly if you have multiple termite species present.

Where to look: Check near baseboards, window sills, and door frames for small piles of what looks like fine sawdust or coffee grounds. In severe infestations, you might notice tiny holes in drywall with frass collecting below.

What to do if found: Collect a sample of the suspected frass for professional identification. Different termite species produce distinct types of frass, which can help determine the appropriate treatment approach.

5. Tight-Fitting Doors and Windows

As termites consume wooden door frames and window frames, the resulting damage and moisture can cause these structures to warp. This warping often leads to doors and windows that suddenly become difficult to open or close.

Where to look: Pay attention to any doors or windows that have recently begun sticking or no longer close properly, especially if there haven’t been significant changes in humidity or temperature to explain the issue.

What to do if found: Examine the frames carefully for other signs of termite activity. While Florida’s humidity can cause some natural swelling of wood, unexplained and persistent warping merits professional inspection.

Don’t Wait Until It’s Too Late

By the time visible signs of termite damage appear, colonies have often been established for years. The average termite colony can consume about one foot of a 2×4 board in six months, with larger Formosan colonies capable of even more rapid destruction.

At F2 Exterminators, we recommend annual termite inspections for all North Port homes, regardless of age or construction type. Our trained technicians use specialized equipment to detect termite activity before visible signs appear, potentially saving you thousands in repair costs.
