Drywood Termites in Sarasota and Manatee County: Why the Flying Insects in Your Window Could Also Be This Pest, and Why Spraying Them Doesn't Solve It
Sep 28
By David Celentano
Quick Answer: If you've spotted winged insects swarming indoors this fall in Sarasota or Manatee County, especially in the evening, you're very likely looking at drywood termites rather than flying ants. Florida hosts more drywood termite species than any other U.S. state, and coastal counties like ours, with a mix of older wood-frame homes and newer construction close to the water, stay active for this pest nearly year-round. Drywood termites don't need soil contact to survive; they live entirely inside dry wood, in an attic, a window frame, or a piece of furniture, sometimes for years before damage becomes visible. Ratical Pest Solutions confirms the species and the extent of activity before recommending treatment, since a spot infestation and a widespread one call for very different approaches.
If you've noticed a handful of winged insects around a window sill, on a porch light, or scattered across an attic floor, your first instinct is probably to assume it's flying ants and sweep them up. That assumption is understandable, but in Southwest Florida it's frequently wrong. Drywood termites swarm to start new colonies, and because they don't need the soil contact that subterranean termites rely on, they can turn up almost anywhere dry wood exists, inside a home in Sarasota, Bradenton, Venice, North Port, Lakewood Ranch, Osprey, Nokomis, Palmetto, Ellenton, Parrish, or Longboat Key.
This guide from Ratical Pest Solutions covers how to tell a drywood termite swarmer from a flying ant, where these colonies actually establish themselves, why Southwest Florida sees this pest more consistently than most of the country, and why treating what you can see rarely solves what's actually happening inside the wood.
Wait, Is That Really Just a Flying Ant?
The short answer: probably not. A swarm of winged insects indoors, particularly in the evening, is one of the more reliable signs of an active drywood termite colony, not a stray group of ants.
Flying ants and termite swarmers get confused constantly because both show up as winged insects moving in groups, often around the same time of year. The differences are consistent once you know what to look for: a termite swarmer has two pairs of wings of equal length, straight antennae, and a thick waist, while a flying ant has unequal-length wings, bent (elbowed) antennae, and a narrow, pinched waist. Termite wings also detach easily and are often found in small piles, separate from the insects themselves, after a swarm has finished.
✓ Rule of Thumb: If the wings are the same length front to back, the antennae look straight rather than bent, and the body doesn't pinch in at the waist, you're looking at a termite, not an ant.
Meet the Real Culprit: The Drywood Termite
The short answer: drywood termites are wood-colonizing insects that live entirely inside sound, dry wood, without any need for soil contact, which is what makes them capable of showing up in so many different parts of a home.
Unlike subterranean termites, which nest in soil and travel into structures through mud tubes, drywood termites establish an entire colony inside a single piece of wood, whether that's a roof rafter, a window frame, a piece of furniture, or a dead tree limb. A colony can persist there for years, slowly expanding its network of tunnels and chambers, with very little visible from the outside until enough wood has been hollowed out.
The clearest sign of an established colony is frass: small, six-sided, sand-like pellets that worker termites push out of tiny "kick-out holes" as they clear space inside the wood. Piles of this frass, often mistaken for sawdust or dead insect debris, are one of the most reliable indicators of active drywood termites, even when no swarmers are visible.
Drywood Termites vs. the Other Wood Pests Homeowners Mix Them Up With
The short answer: drywood termites get confused with several other insects, but the differences change how a problem gets diagnosed and treated.
Drywood termites (the one you most likely have): Live entirely inside dry wood with no soil contact. Leave frass and discarded wings, but no mud tubes. Can establish in an attic, a window frame, furniture, or a dead tree limb.
Subterranean termites: Need contact with soil moisture and travel between the ground and a structure through visible mud tubes. If you see mud tubes running up a foundation wall, you're most likely dealing with this species instead.
Carpenter ants: Larger than a termite swarmer, with a pinched waist, elbowed antennae, and unequal-length wings. They tunnel through wood for nesting space rather than eating it, and they push out coarse wood shavings rather than the sand-like frass drywood termites leave behind.
Ordinary flying ants: Similar in size to a termite swarm but distinguished by the same ant traits, a pinched waist and bent antennae, and they typically disperse quickly rather than leaving frass or wings behind indoors.
For a homeowner, the detail that matters most is this: treating the wrong pest with the wrong method, or treating only what's visible, is one of the most common reasons a wood-destroying insect problem seems to persist after a DIY attempt.
Why Southwest Florida Is Considered Drywood Termite Country
The short answer: this isn't an occasional or random pest here. Florida has more established drywood termite species than any other state, and our coastal location puts Sarasota and Manatee County among the more consistently active parts of the state for this pest.
Several drywood termite species became established in Florida through international shipping and construction trade, and the state's warm, humid climate lets them stay active in ways that colder states don't experience. Coastal counties with a mix of older wood-frame homes and newer construction, like Sarasota and Manatee, tend to see activity throughout the warmer months rather than in a single tight swarm season. That's part of why a Ratical inspection treats the possibility of drywood termites as a standing concern in this area, not a rare event.
Where Drywood Termites Show Up Around Sarasota and Manatee County Homes
Drywood termites aren't picky about which piece of dry wood they colonize, which is a big part of what makes them hard to track down. Attics and roof framing are a common habitat here, since sun-baked rafters and roof decking stay dry year-round and go largely undisturbed. Window and door frames, especially in older construction, are another frequent site. Eaves, soffits, and exterior trim boards offer easy entry points for swarmers looking to start a new colony. Indoors, wood furniture, picture frames, and structural beams can all host a colony that started from a single swarmer years earlier. Outdoors, dead tree limbs, stumps, and stored firewood give colonies a place to establish before some eventually swarm toward a house.
Because a colony can be present in more than one of these places at once, and because drywood termites don't need a moisture source the way many other pests do, treating this as strictly an "attic problem" or a "furniture problem" misses how many different building components can be involved at the same time.
Are Drywood Termites Dangerous?
The short answer: not to people or pets. The risk with drywood termites is entirely structural, not medical.
⚠ What They Actually Do: Drywood termites don't bite, sting, or spread disease. What they do is slowly hollow out the wood they colonize from the inside, which can go unnoticed for years and, left alone long enough, weaken structural or decorative wood components. The real cost of a drywood termite infestation isn't a health risk. It's the accumulated damage from a colony that was never caught early.
Why DIY Spray Treatments Almost Always Backfire
The short answer: a drywood termite colony lives deep inside the wood, and a surface-level spray typically only reaches the insects near the kick-out hole, not the colony itself.
Spraying an over-the-counter aerosol into a kick-out hole may kill a few visible termites, but it rarely penetrates far enough into the wood to reach the rest of the colony, including the reproductive termites that keep it going. Just as importantly, caulking, painting over, or patching a kick-out hole before an inspection removes the evidence a technician needs to judge how active and how widespread the infestation actually is. Treating a single piece of furniture and assuming the rest of the home is clear is another common mistake, since a colony can be present in more than one structural area at once.
DIY Prevention: What Homeowners Should Know
The short answer: there's no reliable do-it-yourself treatment for an established drywood termite colony, but a few habits reduce the odds of one starting in the first place.
Keeping painted or sealed wood surfaces in good repair makes it harder for swarmers to find an entry point, since exposed, unfinished wood is easier for a new colony to establish in. Reducing stacked firewood or dead wood debris near the house limits outdoor staging areas close to the structure. Periodically checking attic framing, window frames, and furniture for small piles of frass can catch a new colony early, while it's still small enough for a straightforward, localized treatment.
When to Call a Professional: If you've found frass, discarded wings, or wood that sounds hollow or feels papery when tapped, or if you've seen winged termites swarming indoors, a professional inspection is what actually confirms whether a colony is active and how far it's spread. Drywood termite damage is often difficult to judge from the surface alone.
How Ratical Pest Solutions Handles Drywood Termite Activity
At Ratical Pest Solutions, we start every suspected termite call with a thorough inspection, covering attic and roof framing, window and door frames, trim, furniture, and any other wood in and around the home, to determine how active the infestation is and how many areas are involved. Depending on what that inspection finds, treatment is typically a localized (spot) treatment aimed at the affected wood. Ratical does not perform whole-structure fumigation directly; for the rare infestation extensive enough to need it, David will explain why and can point you toward a licensed fumigation specialist.
David Celentano, the owner, personally handles the inspection, the treatment, and the follow-up. There's no call center and no rotating crew of technicians, just the same person who has been treating homes across the Sarasota area for more than 20 years. After treatment, Ratical follows up to confirm the activity is resolved and to answer any questions that come up.
Frequently Asked Questions About Drywood Termites in Sarasota and Manatee County
Q: What's the difference between a drywood termite and a flying ant? A: A termite swarmer has two pairs of equal-length wings, straight antennae, and a thick waist. A flying ant has unequal-length wings, bent antennae, and a pinched waist.
Q: Are drywood termites dangerous to people or pets? A: No. Drywood termites don't bite, sting, or spread disease. The risk is structural damage to wood over time, not a health risk.
Q: Why do I keep seeing termite activity after cleaning up a swarm or spraying? A: Swarmers and visible workers are only a small part of the colony. Spraying or cleanup addresses what's visible but rarely reaches the colony deeper inside the wood.
Q: How are drywood termites different from subterranean termites? A: Drywood termites live entirely inside dry wood and don't need soil contact, so they don't build the mud tubes subterranean termites use to travel between soil and a structure.
Q: Is fumigation always necessary for drywood termites? A: Not necessarily. Many infestations can be resolved with a localized spot treatment of the affected wood. Ratical focuses on inspection and spot treatment and refers out to a licensed fumigation specialist for the rare case that needs whole-structure fumigation.
Q: How can I tell if termite damage is old or new? A: It's hard to judge from the surface alone. Fresh, light-colored frass near a kick-out hole suggests recent activity, while damage with no new frass nearby may be old. A professional inspection is the most reliable way to know for sure.
