Are Termites Common In Ohio? And What Else Eats Wood Here
Yes. Ohio State University Extension rates this state's risk of subterranean termite infestation as moderate to heavy, and one species accounts for nearly all of it. It is not the only insect eating wood in Ohio houses, though, and the other four leave evidence a termite never would.
Which Termite Is Actually In Ohio?
The termite in a North Canton basement is almost certainly Reticulitermes flavipes, the eastern subterranean termite. Ohio State University Extension's BYGL bulletin places it among the major destructive structural pest insects in the United States. What matters more at the house is where it lives: subterranean termites need soil contact for moisture, so the colony sits in the ground and the insects you find in a joist are foragers from it. BYGL notes that mud tubes show up on outer walls and pillars near the soil around infested buildings, and that winged reproductives leave through a mud structure called a swarm castle. Swarming here runs through spring and early summer.
That biology is the whole reason termite control is a different kind of work from a general pest visit. A treatment aimed at the insects in the wood leaves the colony intact, so the methods that solve it reach the soil instead: baiting through the Sentricon system, or a liquid barrier.
Why A Statewide Risk Rating Says Nothing About Your House
Moderate to heavy is a regional probability. It does not read your foundation. Two houses on the same Massillon street can sit at very different risk, and the difference is usually one of these conditions:
- Wood touching soil. Siding or trim running down to grade, deck posts set in dirt, stair stringers on the ground, form boards left in place after a pour.
- Water that never leaves. A downspout emptying at the foundation, a crawl space with no vapor barrier, a hose bib that drips against the block.
- Grade or mulch above the sill. When soil and mulch sit higher than the top of the foundation wall, foragers get a covered route into framing that nobody can see from the yard.
- Slabs poured against the house. Porches, stoops and patios hide the soil line exactly where it matters most.
- Older framing close to grade. A lot of the housing stock in Canton, Massillon and Akron was built when framing sat nearer the ground than current practice allows.
The Other Wood Destroying Insects In An Ohio House
Four other groups damage structural or finish wood in this state. The hole sizes and wood preferences below come from Ohio State University Extension's fact sheets on powderpost beetles (HYG-2090), carpenter bees (HYG-2074) and carpenter ants (HYG-2063), and from University of Maryland Extension on the old house borer.
| Insect | What it goes after | What you find | Gets worse on its own? |
|---|---|---|---|
| Carpenter ants | Wood that has been softened by moisture, in and around the structure | Clean, smooth galleries with no soil in them, and borings that look like pencil sharpener shavings | Yes, until the nest itself is found |
| Lyctid powderpost beetles | Large-pored hardwoods only, with oak, ash and hickory highly susceptible; they feed in the sapwood rather than the heartwood because of the starch there | Round exit holes roughly 0.03 to 0.13 inch across, with powder sifting out of them | Yes. Extension flags powderpost beetles as a structural concern because they can re-infest wood already in use |
| Anobiid powderpost beetles | Not restricted to hardwoods, so softwood framing and subfloor are on the menu | Slightly larger exit holes, roughly 0.13 to 0.25 inch | Yes, and damp wood suits them better than dry |
| Old house borer | Softwood timber, mostly pine. It mainly infests wood less than 10 years old but can re-infest much older wood | Oval exit holes about one quarter to three eighths of an inch, with ragged edges, plus rasping or clicking from inside the wood | Yes. The name is misleading: newer framing is the usual target |
| Carpenter bees | Soft, straight-grained wood: cedar, redwood, cypress, pine and fir | A clean round hole slightly under half an inch wide that turns about 90 degrees and runs 4 to 6 inches along the grain | No feeding damage, so the wood is lost to excavation and to the reuse of old galleries |
The carpenter bee row throws people, because the insect doing the damage is a pollinator. Extension is clear that these bees feed on nectar and pollen and do not consume wood at all. The hole is a nursery: a female partitions a gallery into six to 10 brood cells, and the following season her offspring are likely to reuse and extend it rather than start from scratch. Our stinging insect work handles the bees; the beetles and ants are a different conversation.
How Do You Know If It Is Still Going On?
This is the question that actually decides whether anything needs doing, because an exit hole is a record of an insect that already left. Old damage looks the same as new damage.
- Clear the frass and date it. University of Maryland Extension describes the test for the old house borer: fresh sawdust-like frass near the hole or on the floor below is a sign of infestation, and if the piles come back a few weeks after you sweep them up, it is active.
- Listen in a quiet room. The same source notes that rasping or clicking from large larvae can be heard in infested wood, loudest in spring and summer when wood moisture is high.
- Look at which wood got hit. A hardwood floor, an oak stair tread or a piece of ash trim with fine holes points at lyctid beetles and their taste for sapwood starch. Fine holes in softwood framing point somewhere else.
- For termites, there is no hole to watch. Mud tubes do that job. A tube broken open and then rebuilt means traffic is still running through it.
Ohio State University Extension groups powderpost beetles into three families, Lyctidae, Anobiidae and Bostrichidae, and the name comes from what the larvae do: feeding reduces wood to a powder-like consistency. The reason they matter indoors more than the beetles that emerge from firewood is that they can breed in wood that is already part of the house.
What To Do With What You Found
Identification first, treatment second, and in that order for a practical reason. The EPA is direct about it: in most cases termiticide application can only be properly performed by a trained pest management professional who has the knowledge, expertise and equipment the product label requires, and firms offering termite services have to be licensed by the state.
- Put the insect, or a few of the borings, in a sealed bag. A photo with a coin or a tape measure in frame works nearly as well.
- Note where it came from and what the wood is. Finish trim, a floor, a sill plate and a deck post lead to four different answers.
- Leave the wood alone otherwise. Painting or sealing over a hole does not settle whether anything is still inside it.
- Check the moisture while you are down there. Carpenter ants and anobiid beetles both prefer wood that has been wet, so the leak is usually part of the fix.
Termite inspections are free, and that inspection is what decides between baiting and a liquid barrier on a given house. If this came up because you are buying or selling, that is a separate errand: a real estate wood destroying insect inspection is reported on its own form, and we walk through how to read the NPMA-33 elsewhere.

Frequently Asked Questions
Are termites common in Ohio?
Common enough to plan around. Ohio State University Extension rates Ohio's risk of subterranean termite infestation as moderate to heavy, and the species responsible is the eastern subterranean termite, Reticulitermes flavipes, which Extension's BYGL bulletin places among the major destructive structural pest insects in the United States. Because the colony lives in soil and sends foragers up into the structure, a house can have termites for a long time with nothing visible indoors.
What makes tiny round holes in a hardwood floor or oak trim?
Usually lyctid powderpost beetles. Ohio State University Extension's powderpost beetle fact sheet says lyctids attack only large-pored hardwoods, with oak, ash and hickory highly susceptible, and that they feed in the sapwood rather than the heartwood because of the starch content. Their exit holes run roughly 0.03 to 0.13 inch across. Anobiid beetles leave slightly larger holes, roughly 0.13 to 0.25 inch, and are not restricted to hardwoods.
How can I tell whether a wood boring beetle problem is still active?
Clear the frass away and watch the spot. University of Maryland Extension describes fresh sawdust-like frass near an exit hole as a sign of infestation, and says that if the piles reappear a few weeks after being cleared, the infestation is active. It also notes that rasping or clicking from large larvae can be heard in infested wood, most often in spring and summer when wood moisture is high.
Do carpenter bees really damage a house, or do they just look alarming?
They damage wood without eating it. Ohio State University Extension's carpenter bee fact sheet explains that females excavate galleries to raise young and feed on pollen and nectar, which makes them pollinators rather than wood feeders. The excavation is still real: a female bores a round entrance slightly under half an inch wide, turns about 90 degrees and runs 4 to 6 inches along the grain, often building six to 10 brood cells in that one gallery. Eastern species prefer softwoods such as cedar, redwood, cypress, pine and fir, which is why decks, railings and fascia take the hits.
What happens if the inspector finds beetles instead of termites?
You get told that, and the plan changes with it. Termite inspections are free, and the point of the visit is to identify what is in the wood before anyone recommends anything. Termites mean reaching the colony in the soil, through Sentricon baiting or a liquid barrier. A beetle problem confined to one piece of trim or one run of flooring is a much narrower job, and sometimes the honest answer is that the damage is old and nothing is living in it. Either way we collect the details and the team reaches out to schedule.
