Fall in Central Florida doesn’t feel like fall anywhere else. The humidity lingers, daytime temperatures stay warm well into November, and the pest pressure that builds through summer doesn’t just stop when the calendar changes. For Silver Lake homeowners, that means drywood termites can remain active — and hidden — long after you’d expect them to slow down.
The tricky part is that drywood termites rarely announce themselves. They work quietly inside the wood of your home, often for months or years before the damage becomes obvious. Knowing the early warning signs can make a real difference in how much repair work you’re facing down the road.
Why Fall Is Still a Concern for Drywood Termites in Silver Lake
Drywood termites don’t need soil contact to survive, and they don’t rely on moisture the way subterranean termites do. They live entirely inside dry wood — furniture, window frames, door casings, rafters, and structural beams. Central Florida’s mild fall temperatures keep these colonies active far longer than in northern states.
The swarming season for drywood termites in Lake County typically peaks in late summer and early fall. That means any swarmers you noticed in August or September may have already started new colonies inside your home. By the time you see obvious damage, the colony has usually been established for a year or more.
Key Signs of a Drywood Termite Problem
Termite Frass: The Most Reliable Early Clue
Frass is the telltale sign that most homeowners miss — or mistake for sawdust or dirt. Drywood termites push their waste pellets out of small holes in the wood as they feed. These pellets are tiny, about the size of a grain of sand, and they pile up in small mounds beneath infested wood.
Termite frass identification is straightforward once you know what to look for. The pellets are hard, hexagonal in shape, and usually tan to dark brown depending on the type of wood being consumed. A small pile on a windowsill, at the base of a door frame, or on a shelf near wooden trim is worth taking seriously. Sawdust, by contrast, is irregular and flaky — frass is uniform and granular.
Small Exit Holes in Wood Surfaces
Drywood termites create tiny kick-out holes — typically about 1/16 of an inch wide — to push frass out of the colony. These holes are often plugged and hard to see, but if you look closely at window frames, baseboards, exposed beams, or wooden furniture, you may notice small, round openings. Paint may bubble or crack slightly around these spots as well.
Hollow-Sounding Wood
Tap along baseboards, door frames, and window casings with your knuckle. Wood that sounds hollow or papery — rather than solid — may have been eaten from the inside out. Drywood termites consume wood along the grain, leaving a thin outer shell intact while hollowing the interior. This can cause wood to feel soft or crumble under light pressure in more advanced cases.
Discarded Wings Near Windows and Doors
When drywood termite swarmers find a new place to start a colony, they shed their wings almost immediately. Finding small, translucent wings — often in pairs — along windowsills, door thresholds, or near light fixtures is a sign that swarmers have recently entered or emerged from your home. This is one of the most visible early drywood termite signs you’ll encounter.
Where to Check in Your Silver Lake Home
Drywood termites tend to target specific areas of a home. Focus your inspection on these locations:
- Window and door frames — especially on the south and west-facing sides of the home that get the most sun exposure and experience more wood movement
- Attic framing and rafters — a very common entry point that goes unnoticed for years
- Wooden furniture — particularly antique or older pieces with untreated wood
- Garage door frames and trim — these get repeated heat and humidity exposure
- Fascia boards and eaves — exterior wood near the roofline is a frequent target
- Hardwood floors and baseboards — look for frass accumulation along the edges of rooms
If you find frass or kick-out holes in more than one location, that may indicate multiple infestation points rather than a single small colony. That distinction matters a lot when it comes to treatment planning.
What Makes Termite Damage Diagnosis Difficult
One of the frustrating realities of termite damage diagnosis is that the most active feeding happens well out of sight. Drywood termites prefer the inner layers of wood, so surface damage is often the last thing you notice. By the time a beam or frame shows visible deterioration, the colony has been feeding for a long time.
This is especially relevant in older homes in Silver Lake and throughout Lake County, where original wood construction may have gone untreated for decades. If your home was built before the 1980s and has never had a professional inspection, there’s real value in having a trained set of eyes look things over — even if you haven’t spotted any obvious signs yet.
The Pest 911 Silver Lake service team has been helping Central Florida homeowners catch these problems early since 1985. A trained inspection looks at all the areas a casual walkthrough misses.
The Difference Between Drywood and Subterranean Termites
It helps to know which type of termite you’re dealing with before treatment begins. Subterranean termites build mud tubes from the soil up into wood, and they require moisture to survive. If you see pencil-width mud tubes running up your foundation or along a wall, that points to subterranean activity.
Drywood termites leave no mud tubes. They live entirely inside the wood and only need minimal moisture. Frass piles with no mud tubes strongly suggest a drywood infestation. Both types cause serious damage, but professional drywood termite treatment in Silver Lake involves different methods than subterranean control — which is why accurate diagnosis matters.
When to Call for Help
You don’t need to find every sign on this list to take action. A single frass pile, one set of discarded wings, or hollow-sounding wood in a frame is enough reason to schedule an inspection. Early-stage colonies are far easier to address than established infestations that have spread to multiple areas of a home.
Pest 911 has been serving Lake County homeowners for decades, and our team understands the specific termite pressure that Central Florida’s climate creates year-round. If you’re seeing signs you’re not sure about, getting a professional opinion early is always the right call.
For homeowners in surrounding communities, our team also provides pest and termite services in Leesburg and Tavares pest and termite control throughout Lake County.
If something around your Silver Lake home has caught your attention — a small pile of granules, wings near a window, or wood that doesn’t sound right — give Pest 911 a call at 352-629-9111. We’re happy to take a look and give you a straight answer.
Frequently Asked Questions
What does drywood termite frass actually look like?
Drywood termite frass consists of tiny, hard pellets roughly the size of a grain of sand. They are hexagonal in shape and range in color from tan to dark brown, depending on what type of wood the termites are feeding on. You’ll typically find them in small, neat piles beneath kick-out holes in infested wood — unlike sawdust, which is irregular and powdery. Frass does not crumble easily when pressed.
Can drywood termites spread from furniture to the structure of my home?
Yes, they can. Drywood termites in an infested piece of furniture can potentially spread to nearby wooden elements in your home, particularly if the furniture stays in place for an extended period. This is one reason why finding termites in furniture should be treated as a whole-home concern rather than an isolated problem. A professional inspection can help determine whether spreading has occurred.
Are drywood termites more active in a specific season in Central Florida?
Drywood termites in Central Florida tend to swarm most heavily in late summer through early fall, typically from August into October. However, because our winters are mild, colonies remain active and continue feeding throughout the cooler months. Silver Lake homeowners should not assume that fall weather signals a reduction in termite activity — the colony feeding cycle continues year-round in this climate.
How is drywood termite treatment different from subterranean termite treatment?
Subterranean termite treatment typically targets the soil and foundation, using liquid barriers or bait systems to intercept termites traveling from the ground. Drywood termite treatment focuses on the wood itself, since these termites never touch soil. Treatment options can include localized wood injection, fumigation for widespread infestations, or other methods depending on the extent and location of the colony. A proper diagnosis determines the right approach.
Should I be concerned if I only found a small pile of frass once?
A single frass pile is worth investigating rather than ignoring. Small piles can indicate an early-stage colony, which is the best time to address the problem before it spreads. Termites push frass out intermittently, so you may not see a new pile every day. If you find frass once and then don’t see it again, the colony is still likely present — it may have simply sealed the kick-out hole temporarily.
How long does it take for drywood termites to cause serious structural damage?
Drywood termite colonies grow more slowly than subterranean colonies, but they are still capable of causing significant structural damage over time. Serious damage typically develops over several years of unchecked activity. The challenge is that the damage is hidden inside the wood for most of that period, which is why regular inspections are more effective than waiting for visible signs to appear on wood surfaces.
