If you’ve been noticing small winged insects emerging from your walls, window frames, or furniture — don’t ignore them. Drywood termite swarmers are here, and right now across Port St. Lucie, Stuart, Vero Beach, Jensen Beach, and the entire Treasure Coast, they are actively searching for their next home to destroy.
Drywood termites are one of the most destructive and misunderstood pests in South Florida. Unlike subterranean termites that live underground, drywood termites live, eat, and breed entirely inside the wood of your home — silently consuming it from the inside out for months or even years before you ever notice a single sign.
And swarming season? That’s when things get serious. When drywood termite swarmers take flight, it means colonies are actively spreading — looking for new wood to infest. Your home, your furniture, your roof, your walls — all of it is a target.
At Hannan Environmental Services, we’ve been protecting Treasure Coast homes and businesses from drywood termites since 2001. This guide covers everything you need to know about drywood termite swarmers — and exactly what to do right now to protect your home.

What Are Drywood Termite Swarmers?
Drywood termite swarmers — also called alates — are the reproductive members of a drywood termite colony. When a colony matures and conditions are right, it produces winged swarmers whose sole purpose is to fly out, find a mate, and start new colonies in fresh wood.
Swarming typically occurs on warm, sunny days following periods of rain — exactly the kind of weather the Treasure Coast experiences throughout spring and early summer. Swarmers are attracted to light and are often first noticed near windows, light fixtures, and doorways inside your home.
Swarmers vs. Flying Ants — How to Tell the Difference
Many homeowners mistake drywood termite swarmers for flying ants. Here’s how to tell them apart:
Drywood Termite Swarmers:
- Straight, beaded antennae
- Thick waist with no pinch
- Two pairs of equal length wings
- Wings are twice the length of their body
- Pale to medium brown in color
Flying Ants:
- Elbowed antennae
- Pinched waist
- Unequal wing lengths — front wings larger than back wings
- Darker in color
When in doubt — don’t guess. Contact Hannan Environmental Services for a free inspection and let our trained technicians identify exactly what you’re dealing with.
Why Drywood Termites Are So Dangerous
Drywood termites are uniquely dangerous for several reasons that set them apart from other termite species:
They Live Inside Your Wood
Unlike subterranean termites that build mud tubes from the ground up, drywood termites live entirely inside the wood they consume. This means they can infest virtually any wooden structure in your home — roof rafters, wall framing, window frames, door frames, hardwood floors, wooden furniture, and even picture frames — without any contact with soil.
They Are Nearly Impossible to Detect Early
Because drywood termites work entirely inside wood, they leave almost no visible signs until the infestation is well established. A colony can quietly consume wood inside your walls for 2-3 years before you notice anything unusual. By the time most homeowners realize they have a problem, significant structural damage has already been done.
They Spread Through Swarming
Every swarming season, established drywood termite colonies release hundreds of swarmers that fly to new locations and start fresh colonies. This means a single infested piece of furniture brought into your home can start a new colony inside your walls. Infested homes can also spread termites to neighboring properties through swarming.
They Are Active Year Round in South Florida
Unlike northern states where cold temperatures slow termite activity, South Florida’s warm climate allows drywood termites to remain active and feeding 365 days a year. There is no off season for termite damage on the Treasure Coast.
The Financial Damage Is Devastating
Drywood termites cause billions of dollars in property damage across the United States every year — damage that is almost never covered by standard homeowners insurance. A severe drywood termite infestation can cost tens of thousands of dollars to repair, including replacing structural wood, drywall, flooring, and roofing materials.
Warning Signs of Drywood Termite Swarmers in Your Home
Knowing what to look for can mean the difference between catching an infestation early and facing catastrophic damage. Here are the most critical warning signs:
Seeing Swarmers Inside Your Home
If you see winged insects emerging from walls, ceilings, or wooden surfaces inside your home — especially near light sources — this is the most urgent warning sign possible. Swarmers inside your home almost always mean an established colony is already living inside your wood. Call us immediately if you see swarmers indoors.
Discarded Wings
After swarming, drywood termites shed their wings. Finding small piles of tiny wings near windowsills, doorways, light fixtures, or on your floors is a telltale sign that swarmers have recently emerged nearby. Even if you don’t see the swarmers themselves, discarded wings are a serious red flag.
Frass — Termite Droppings
Drywood termites push their droppings — called frass — out of tiny kick out holes in infested wood. Frass looks like tiny hexagonal pellets, often resembling sawdust or coarse sand, and is typically found in small cone shaped piles beneath infested wood, on windowsills, or on furniture. This is one of the most reliable indicators of an active drywood termite infestation.
Hollow Sounding Wood
Tap on wooden surfaces throughout your home — walls, baseboards, door frames, windowsills, and furniture. If the wood sounds hollow instead of solid, drywood termites may have consumed the interior. Healthy wood sounds solid and dense. Termite damaged wood sounds papery and empty.
Blistering or Bubbling Paint
Paint that appears to be bubbling, peeling, or blistering on wooden surfaces can sometimes indicate termite activity beneath the surface. As termites consume wood and produce moisture, it can cause paint to lift and bubble even when there’s no water damage present.
Tight Fitting Doors and Windows
As drywood termites damage wooden door and window frames, the wood can warp and swell making doors and windows difficult to open and close. If you’ve noticed this recently and can’t explain it by weather changes, termites may be the cause.
Visible Damage to Wood Surfaces
In advanced infestations, you may be able to see actual damage to wooden surfaces — small holes in wood, crumbling wood edges, or sections of wood that crumble when pressed. At this stage the infestation is severe and requires immediate professional termite treatment.
Where Drywood Termites Hide in Your Home
Drywood termites can infest virtually any dry wood in your home. Here are the most common areas where they hide:
Roof and Attic
The attic is one of the most common entry points for drywood termite swarmers. Roof rafters, eaves, fascia boards, and attic framing are all prime targets. Because attics are rarely inspected, termite infestations here often go undetected for years.
Wall Framing
Interior wall framing provides miles of wood for drywood termites to consume inside your walls. By the time they’ve caused significant structural damage inside your walls, the infestation can be severe.
Window and Door Frames
Wooden window and door frames are frequent entry points for swarmers looking for a place to start a new colony. Their location near light sources also makes them prime targets during swarming season.
Hardwood Floors
Drywood termites can infest hardwood flooring from below, consuming the wood from the inside while leaving the surface looking perfectly normal until the damage is severe.
Wooden Furniture
Unlike subterranean termites, drywood termites readily infest wooden furniture — including antiques, cabinets, bed frames, and decorative wooden pieces. Infested furniture brought into your home can introduce a new drywood termite colony to your living space.
Baseboards and Trim
Wooden baseboards and decorative trim throughout your home are vulnerable to drywood termite infestation, especially where they meet exterior walls.
Drywood Termite Treatment Options
If you suspect drywood termite swarmers have entered your home, acting quickly is absolutely critical. Here are the treatment options available:
No Tent Termite Treatment
Our most popular treatment option for drywood termites. No tent termite treatment targets specific areas of infestation using highly effective localized treatments — without the need to vacate your home or tent your entire property. This is an excellent option for localized infestations and for homeowners and businesses that cannot afford significant disruption.
Tent Fumigation
For widespread drywood termite infestations throughout a structure, tent fumigation remains the most comprehensive treatment available. The entire structure is covered with a tent and fumigated with a gas that penetrates all wood throughout the building, eliminating every termite in every stage of development. Occupants must vacate for 2-3 days. This is the gold standard for severe or whole house drywood termite infestations.
Wood Treatment
Direct wood treatments involve applying termiticide directly to infested or vulnerable wood surfaces. This is often used as a preventative measure on exposed wood in attics, crawl spaces, and during construction or renovation.
Heat Treatment
Localized heat treatment raises the temperature inside infested wood to levels that kill termites in all stages of development. This is a chemical free option suitable for treating specific pieces of furniture or localized areas.
The Right Treatment for Your Home
The best treatment depends on the extent of the infestation, the species involved, and the construction of your home. A professional termite inspection is always the essential first step to determining the right approach for your specific situation.
Why South Florida Homes Are Especially Vulnerable
The Treasure Coast faces a uniquely high drywood termite risk for several reasons:
Year Round Warm Climate
South Florida’s warm temperatures mean drywood termites never go dormant. They feed, breed, and swarm throughout the entire year — giving them far more time to damage your home than termites in cooler climates.
High Humidity
While drywood termites don’t need contact with soil or moisture to survive, Florida’s humidity creates the warm moist conditions that support massive swarming events.
Older Construction
Many homes throughout Port St. Lucie, Stuart, and the surrounding Treasure Coast were built decades ago using older construction methods that offer more entry points and more exposed wood for termites to target.
Dense Neighborhoods
In established neighborhoods, drywood termite swarmers from one infested home can easily spread to neighboring properties — making community wide awareness and treatment essential.
How to Prevent Drywood Termite Swarmers From Entering Your Home
While professional treatment is the most effective solution, there are steps you can take to reduce your risk:
Seal Entry Points
Inspect and seal all cracks, gaps, and openings in your home’s exterior — especially around window frames, door frames, eaves, and utility lines. Swarmers need only a tiny opening to enter and start a new colony.
Screen Attic Vents
Make sure all attic vents are properly screened with fine mesh to prevent swarmers from entering your attic — one of their favorite entry points.
Inspect Secondhand Furniture
Before bringing any secondhand or antique wooden furniture into your home, inspect it carefully for signs of drywood termite activity — frass, small holes, or hollow sounding wood.
Paint and Seal Exposed Wood
Properly painted and sealed wood surfaces are less attractive to drywood termite swarmers looking for a place to start a new colony. Maintain exterior paint and seal any exposed wood surfaces around your home.
Schedule Annual Termite Inspections
The single most important prevention step is an annual professional termite inspection. A trained technician can identify early signs of drywood termite activity before serious damage occurs — potentially saving you tens of thousands of dollars in repairs.
Maintain Your Property
Keep your property well maintained with professional lawn and shrub care to reduce conditions that attract termites and other pests around your home.
What To Do If You See Drywood Termite Swarmers
If you see drywood termite swarmers in or around your home, here is exactly what to do:
Step 1 — Don’t panic, but don’t wait. Seeing swarmers is alarming but the swarmers themselves don’t cause damage. The danger is the colony they came from or the new colony they are about to start.
Step 2 — Collect a sample. If possible, collect a few of the swarmers or their shed wings in a zip lock bag. This helps our technicians confirm the species and recommend the right treatment.
Step 3 — Note where you saw them. Make a mental note of exactly where the swarmers emerged — near a window, from a wall, from furniture. This gives our technicians a starting point for the inspection.
Step 4 — Call Hannan Environmental Services immediately. Contact us right away for a free inspection. The faster we can assess the situation the better your chances of catching the infestation before serious damage occurs.
Step 5 — Don’t disturb the area. Avoid drilling, painting over, or disturbing the area where you saw swarmers until our technicians have had a chance to inspect it.
