Adults come out mainly spring through late summer, and a warm indoor space can stretch that window at both ends.
Powderpost beetles leave round exit holes in hardwood with a dust like spilled flour beneath them. Wipe the pile away and write the date on the wall behind the trim: fresh powder returning inside two weeks separates a live infestation from holes left twenty years ago, and that one test saves a lot of money. They appear on Florida's WDO report alongside termites, so they can stall a closing. What decides whether they stay is how wet the wood is, not what gets sprayed on it.
Spring swarming season follows the warm, humid stretch from February through May
Between a pin and a pencil lead across, with clean edges. Age them by color rather than by counting: gray and dull inside means old and empty, pale bright wood at the rim means recent. A ceiling of gray holes in a house from the 1950s is a record of something that finished decades ago, and plenty of people pay to treat exactly that.
Rub it between finger and thumb, because the texture is the identification. Powderpost frass is soft and floury with no grit in it at all, and it gathers in small cones directly under the holes or streaks down anything vertical. Anything gritty, or containing small pellets, is a different beetle and a different job.
This is the only test worth trusting and it costs nothing. Vacuum the pile away, write the date on the wall behind the trim where nobody will paint over it, and look again in two or three weeks. Nothing new means the emergence finished, possibly years ago. A fresh pile means larvae are still feeding inside and the moisture that suits them has not changed.
What decides this one is the wood, not the neighborhood. Older Leon County houses with oak strip flooring, solid hardwood stair parts and real wood trim give these beetles exactly what they feed on, and so does hardwood furniture shipped in from overseas or reclaimed lumber carried into a brand new house. A slab home from the nineties with engineered flooring is a poor host by comparison, which is why the calls lean so heavily toward one kind of property.
Moisture is the local half of it. Surface water disappears off Red Hills soil in a hurry and then sits in the layer beneath, so a crawl space built over that ground runs at a noticeably higher humidity than the rooms above it. Hardwood subfloor and joists that spend twelve months a year taking up that vapor make a welcoming host in a way the identical wood in a dry conditioned room never does.
The same wood-moisture pattern shows up well beyond Tallahassee's grid, since old growth heart pine framing was common wherever mills shipped it. Out toward Havana, the pros we connect you with have pulled frass from joists near Havana Main Street and the old tobacco barns along the US 27 corridor, structures old enough to have hosted a beetle generation or two before anyone spotted an exit hole. Quincy's older stock near the Quincy Historic District tells the same story, decades of slow reinfestation nobody noticed until the wood surface started to crumble.
The same exit-hole pattern shows up east of Tallahassee toward Lloyd, where clapboard homes in the Lloyd Historic District and along the US 90 corridor were built from the same regional lumber runs decades ago. Closer to Killearn Lakes, older beams near Bannerman Road and the Killearn Lakes greenbelt shed frass quietly behind trim and siding for years before anyone noticed the surface had gone soft and powdery underneath.
Along Thomasville Road and out toward Bradfordville, newer subdivisions and older infill sit close together, so pest pressure varies block to block. A licensed pro who knows whether a house backs up to Lake Overstreet or sits on cleared lawn treats the yard differently before touching the house itself.
Old house borer holes. Powderpost holes are round, small, in hardwood, with frass as fine as talc. Old house borer exit holes are oval, considerably bigger, in softwood framing, and their frass feels gritty between your fingers. Getting the two the wrong way round matters, because one is a story about your flooring and trim and the other is a story about the framing holding the roof up, and the work goes to opposite ends of the house.
The first question is whether anything is still alive in there. A hardwood floor can carry holes decades old from a single emergence that finished long before you bought the place, and treating that is buying history. Clean the frass out, mark the date, come back and look again, and open up a small patch of subfloor or crawl space wood if the answer is still not obvious.
Once activity is confirmed there are three practical routes and they work together. A borate solution on bare unfinished wood, which the larvae take up as they feed. Replacing a board or a length of trim riddled past saving. And above all, correcting the moisture: a vapor barrier laid over crawl space soil, gutters and downspouts that actually work, and ventilation with no dead pockets left in it. Wood sitting at 20 percent moisture or higher is a reportable conducive condition on a WDO report for a reason. Bring the moisture down and the habitat goes with it, which is something no surface spray will ever do to a finished floor.
Betton Hills sits on clay soil that holds water after a storm, the kind of ground eastern subterranean termites move through easily on the way to a slab or a crawl space. Older homes near Lake Ella often have pier-and-beam foundations, which give inspectors a clear look underneath. The licensed pros we connect you with check both foundation types the same way, on the same visit.

Powderpost beetles are one of the insects commonly noted on the Florida Wood-Destroying Organisms Inspection Report, form DACS-13645, so they can show up in a real estate transaction. The report covers present and past evidence, which is precisely why old, inactive holes appear on reports and alarm buyers. It is not a damage report and it is not a warranty, and a note of past evidence is not a reason to walk away from a house.
Losing real structure to these is uncommon. Losing the look of a floor is not. A hardwood floor pitted with small holes, or a stair tread that gives slightly underfoot, is the usual result, and the repair is board replacement followed by refinishing. The sanding stage is the moment the true extent of the tunneling finally shows, which catches most people out. Sort the moisture before new wood goes down, or the replacement simply inherits the same conditions.
The diagnosis is the valuable part and you can do all of it yourself. Sweep the frass away completely, write down the date, photograph the holes with a coin next to them so the scale is obvious, and check what the humidity is doing in the crawl space. Where money gets wasted is on a general insecticide bought for a finished floor. The larvae are inside the wood, the finish holds the product on the surface, and the two never meet.
Betton Hills to Bradfordville, one call gets a licensed pro looking at your actual problem, not a guess.Looking costs you nothing, and the number is on paper before anybody starts. The pricing guide lists each range and what pushes one higher, and that work is listed under Termite Control.
Excavates damp wood. Does not eat it. Carpenter ants do not eat wood, they hollow out wood that water already softened, then push the shavings out through a crack.
Many queens. Splits when disturbed. If a trail comes back a day after you sprayed it, wider than before, this is why.
Strong flier. Works from the roofline down. This is the roach a tree canopy gives you.
Sweep every trace of frass away, write down the date, and look again in two or three weeks. Fresh powder means active feeding. Nothing new means you are looking at an emergence that finished some time ago. The rim of the hole helps as well: pale bright wood suggests recent work, gray weathered edges suggest age.
Easily. Solid hardwood furniture, reclaimed beams and imported wooden items are all realistic sources, and it explains the situation people find most puzzling, where one chair leg or a single length of trim shows holes and nothing else in the room does.
The species that go after hardwood have very little interest in the pine and fir this area frames with. That is a different insect with a different story attached. What does travel from one to the other is the condition rather than the beetle, because damp wood attracts several wood-destroying organisms at the same time.
It breaks into three parts: the inspection, any borate application, and the moisture work. The moisture work is usually the biggest of the three and also the one that pays you back elsewhere in the house. Crawl space treatment is published locally from about $95, and the licensed pros we connect you with generally come in under that at an estimated $55 to $95 as an add-on. Guides rather than quotes.
West of Tallahassee toward Wakulla County, copperheads show up where most of Florida never sees one, so yard work near Elinor Klapp-Phipps Park deserves a second look.
