Darke County ranks first in Ohio for livestock, poultry and products. If you live here, that fact is why your house gets what it gets.
We are a residential pest control company. We treat houses — in Greenville, in Versailles and Arcanum and Union City, and out along the section roads where the nearest neighbor is a field. The operations themselves have people who handle that side of it, and we are not trying to take that work.
But you cannot treat a house in Darke County sensibly without understanding what surrounds it. Living in the top livestock county in the state, on ground that is farmed right up to the property line, produces a specific set of problems at a specific time of year — and most of them have nothing to do with how clean your house is.
Every Darke County community, by name
Darke runs from the Miami County line west to Indiana, and it is one of the least densely populated counties we serve. We cover all of it:
- Greenville — the county seat, around 12,700 people, and the treaty town
- Villages: Versailles (2,692), Arcanum (about 2,300), Union City (1,582, straddling the Indiana line), Ansonia, Bradford, Gettysburg, Hollansburg, New Madison, New Weston, North Star, Osgood, Palestine, Pitsburg, Rossburg, Wayne Lakes, Yorkshire, Burkettsville and Ithaca
- Townships: Adams, Allen, Brown, Butler, Franklin, German, Greenville, Harrison, Jackson, Liberty, Mississinawa, Monroe, Neave, Patterson, Richland, Twin, Van Buren, Wabash, Washington and York
If your address is in Darke County and your community is not listed, you are still covered. Call (937) 569-3330 and we will tell you honestly whether we can get to you.
What living in a livestock county does to a house
Three things, and none of them are your fault.
Flies drift. Where there is livestock there is manure, and where there is manure there is a fly population that exists whether or not anyone treats anything. If you live within drift distance of a barn or a spread field, those flies reach your porch, your kitchen door and your garage. Nothing sprayed on your house eliminates a population being produced somewhere else — so the honest work here is keeping them out: door sweeps that actually meet the threshold, screen repair, sealing the gaps around service penetrations, and treating the surfaces they rest on. We can make a real difference to what gets inside. We cannot make your neighbor’s operation disappear, and we will not pretend otherwise.
Rodent pressure never really stops. In a crop-only county, mice push toward houses at harvest and things quieten down afterward. Here, feed is stored and animals are fed every day of the year, so there is a permanent food supply in the landscape and a permanent population living on it. For a house that means the pressure is continuous rather than seasonal, and a one-off treatment in November is working against a tide. What holds up is exclusion — sealing the ways in — backed by a serviced perimeter rather than a single visit.
Harvest empties the fields all at once. Several hundred acres of cover becomes bare dirt in an afternoon, and everything living in it needs somewhere warm by dark. The nearest structure is your house, your garage or your shed. This is why the busiest three weeks of our Darke County year are late September into October, and why the single most useful thing on this page is about timing: seal the house in August, before the combines run. The same work costs less and accomplishes far more done ahead of the push than after it.
The bag in the garage
The single most common misdiagnosis we correct in Darke County households is the whole-house moth infestation that is actually one bag in the garage.
Indian meal moths, sawtoothed grain beetles and weevils do not fly in through a window. They arrive in a sack — birdseed, dog or cat food, chicken feed for the backyard flock, a bag of corn for the deer, grass seed. It sits in the garage or the mud room, and by the time anyone notices moths in the kitchen, the source has been quietly producing them for weeks two rooms away.
So on these calls we inspect the garage, the mud room and the pantry before we treat anything on the exterior. Find the bag, remove it, deal with what escaped, and the problem ends. Treat the outside of the house and it does not. Storing pet food and birdseed in sealed hard containers rather than the paper sack they came in prevents nearly all of it.
Cluster flies belong in the same category of misunderstanding. Their larvae parasitize earthworms in sod and pasture ground, so they are a rural insect specifically — nothing whatever to do with sanitation. They warm on south and west walls on sunny October afternoons and work their way into attics and upper-story windows. A homeowner who thinks they have a hygiene problem is looking at entirely the wrong cause, and the fix is sealing and treating those elevations ahead of the season.
Greenville: the treaty town
On the third of August, 1795, the Treaty of Greenville was signed at Fort Greene Ville, ending the Northwest Indian War. Greenville grew up on that ground and is still the county seat, at around 12,700 people.
Annie Oakley is the county’s other permanent resident of the history books — born Phoebe Ann Mosey north of Versailles in 1860, buried at Brock Cemetery eleven miles north of Greenville, and remembered at the Garst Museum and the festival that carries her name.
What matters for our purposes is that a town founded in 1795 has old houses. Greenville’s core housing runs from the mid-nineteenth century into the 1930s, which means stone and rubble foundations, balloon framing, and sill plates that have been sitting on damp masonry for a very long time.
Balloon framing is the detail that catches people out. The wall studs run uninterrupted from sill plate to roofline with no fire blocking between floors, so a mouse that finds a gap in a stone foundation in October does not stay in the basement — it uses the stud bay as a vertical route and appears in an upstairs closet in November, and the homeowner cannot work out how it got there. On that kind of house, bait alone is a subscription rather than a solution. The durable answer is exclusion: finding the actual openings and packing them with copper mesh and steel wool, which a rodent cannot chew, rather than expanding foam or caulk, which it can.
Versailles, Arcanum, Union City and the villages
Darke’s villages are small, old and surrounded on every side by production ground, which gives their houses a consistent profile.
Versailles, at 2,692, sits in the north of the county in the heart of the livestock country and carries the fly and rodent pressure that comes with it. Arcanum, around 2,300, anchors the southeast toward the Miami and Preble lines. Union City is the unusual one — 1,582 people on the Ohio side of a line running straight through the middle of a single built-up place, with Union City, Indiana on the other. Ansonia, New Madison, Gettysburg, Pitsburg, Osgood, North Star and the rest are smaller again.
Three things hold true across nearly all of them. The housing is old, so the stone-foundation and balloon-frame problem applies at village scale. There is usually more ground clearance around a village house than around a house on a city block, which makes exclusion work easier and cheaper here than it is in Hamilton or Springfield — genuinely good news for a homeowner. And every one of these villages has a field starting within a few hundred yards of its edge, so the autumn movement arrives on the combine’s schedule rather than the calendar’s.
Garages, sheds and detached outbuildings are the other constant, and they are where the spiders are. Most of what turns up is harmless, but our guide to the two Ohio spiders that genuinely matter is worth two minutes before you reach into a woodpile.
The Darke County pest calendar
Darke is the northwestern corner of our territory and runs a few days behind Butler in the spring.
- March and April. Overwintered stink bugs, Asian lady beetles and boxelder bugs emerge from wall voids at the windows — they have been in that wall since October, which is the correction we make most often. Ants begin moving, and fly activity starts climbing well before it does in town.
- May and June. Termite swarm season, and the annual question of whether a pile of wings on a windowsill means termites or flying ants — the difference is in the waist, the wings and the antennae. Carpenter bees start drilling soffits, deck rails and shed boards.
- July and August. Peak fly season, peak mosquito in the creek bottoms, and wasp and hornet nests reaching the size people notice. Yellowjacket ground nests found with a mower produce the worst sting incidents of the year. This is the window for exclusion work, before harvest.
- September through early November. The busiest stretch, driven entirely by harvest. Fields come off, cover vanishes in an afternoon, and everything living in it moves toward the nearest warm building. Cluster flies press the south and west walls on sunny days.
- November through February. Rodents indoors and breeding. Mice do not hibernate — a pair that got in during October has produced several litters by February, which is why “a couple of mice in the fall” is a different animal by spring. It is also the clearest window for spotting entry points, with the vegetation down.
The country house: what is actually different out here
A house on a section road is not a suburban house with a longer driveway. A few things genuinely change.
- The perimeter is the whole job. With open ground on every side there is no neighbor’s house acting as a buffer, so the pressure arrives at your foundation directly. A serviced exterior perimeter does far more here than interior treatment does.
- The attached garage is the front line. It is the least sealed part of most rural houses — a door seal that no longer meets the slab at the corners is the single most common rodent entry we find, and the garage is usually where the pet food, the birdseed and the grass seed are stored as well.
- Well and septic country changes the moisture picture. Leach fields, downspouts discharging beside the foundation and crawl spaces without a vapor barrier support the whole damp-loving insect complex — springtails, silverfish, camel crickets and the house centipedes that hunt them.
- Detached buildings need a decision. A shed, a barn or a corn crib on a residential property is a harborage, and it is worth being deliberate about whether it is in scope. We will tell you honestly when treating an outbuilding will change things for the house and when it will not.
- Wildlife is somebody else’s job. More on that below, but out here it comes up constantly and it is worth knowing before you call.
Termites, WDI inspections and old country houses
Darke County property transfers frequently involve a nineteenth-century house, and that raises the stakes on a wood-destroying insect inspection.
We run termite and WDI inspections at a flat $99 on the lender-ready NPMA-33 form, next business day for realtors. On a house with a porch that has been rebuilt twice and a sill plate resting on stone, that inspection is worth having whether or not the lender demands it — the questions that decide a deal are whether damage is old or active, and whether the structure is sound where nobody can see.
One Darke-specific warning: if the property includes a garage, shed or barn, say so up front. A WDI report does not automatically cover outbuildings, and on a country property they are frequently where the finding turns up. Sorting that out before the inspection rather than at closing saves an argument.
On treatment, we generally favor bait stations over a liquid barrier on this county’s older housing, for the same reason we do in Greenville and Springfield: you cannot reliably establish an unbroken chemical barrier against an irregular, patch-repointed century-old foundation, and baiting means far less drilling into an old structure.
What we do not do
We are a residential company, and we do not work inside livestock or poultry operations. That work is governed by product labels, residue rules and applicator categories that sit outside what we are licensed for, and the operations here already have people handling it. If you run one, we are not the right call.
We also stop at rats and mice. No raccoons, groundhogs, opossums, skunks, squirrels or bats — and in a county of barns, corn cribs and creek bottoms that call comes in constantly. Anything larger than a rat needs a licensed wildlife control operator and we will point you toward one rather than take a job we are not right for. We do not exterminate honeybees; a swarm or an established hive belongs with a beekeeper.
And we will not sell a recurring plan to somebody who needs one treatment, or pretend that flies drifting from a working farm are something a treatment on your house can eliminate.
What it costs in Darke County
Darke is the farthest corner of our territory and we still do not charge a distance premium for it.
- One-time treatment, common pests: from $129 — ants, spiders, roaches, wasps, mice
- One-time treatment, harder pests: from $199
- Termite and WDI inspection: flat $99, NPMA-33 form, next business day for realtors
- Protection Plan: around $63 a month bundled, covering the common pests on a scheduled rotation
- Exclusion work: quoted on what your house actually needs, after we look at it
The re-treatment guarantee is part of the Protection Plan: while you are on the plan, if a covered pest returns between scheduled visits we come back and re-treat at no additional charge. That guarantee belongs to the plan rather than to every one-time job, and we would rather say so plainly here than have you find out later. On a rural property with continuous outside pressure, the recurring plan genuinely does outperform one-off visits — that is not an upsell, it is what the pressure is like. Full detail is on our pricing page.
What the eighth county completes
Darke came in alongside Clark and Butler to take us from five counties to eight, and it pushed our rural residential practice the furthest.
Clark taught us the crop-country autumn — 164,000 farmed acres and a fall invasion that arrives on the combine. Darke taught us what it is like for a household when the pressure never lets up: continuous rather than seasonal, with flies and rodents produced by a landscape the homeowner does not control. Preble and the west of Butler sit between the two.
It also gave the territory its western edge. From Greenville to Springfield is a long way across, and the whole middle of it is one continuous problem — old houses on stone foundations, surrounded by the most productive ground in Ohio.
Our full territory: Montgomery, Greene, Miami, Clark, Warren, Butler, Preble and Darke counties. The rest is mapped on our service areas page.
The whole county, covered
Darke County is a treaty town from 1795 and a scatter of old villages set in the top livestock country in Ohio. If you live in one of those houses, the problems are specific, they are seasonal in a way you can plan around, and they are solvable by somebody who understands the ground you live on.

Darke County, town by town
Deeper guides to how this plays out where you actually live:
- Greenville — the treaty town: 1795 ground, old stone foundations and the October harvest push.
- Versailles — the heart of the livestock country: flies that drift, and rodent pressure that never stops.
- Arcanum — where three counties nearly meet, at the seam between livestock country and the crop grid.
- Union City — one town across two states — we are Ohio-licensed and cannot treat the Indiana side.
Frequently asked questions
Do you cover all of Darke County?
Yes — Greenville, Versailles, Arcanum, Union City, Ansonia, New Madison, Gettysburg, Pitsburg, Osgood, North Star and every township out to the Indiana line, including houses on open country roads. There is no distance surcharge.
Do you work on farms?
No — we are a residential company. We treat the house you live in. Livestock and poultry operations are governed by rules and applicator categories outside what we are licensed for, and the operations here already have that side handled. If you live in a house surrounded by farm ground, though, you are exactly who this page is for.
Can you do anything about the flies from the farm next door?
We can make a real difference to how many get inside, and that is the honest promise. Door sweeps that meet the threshold, screen repair, sealing service penetrations and treating the surfaces they rest on all work. What no treatment on your house can do is eliminate a fly population being produced on somebody else’s ground — anyone promising that is selling you something.
Why do I get mice every October like clockwork?
Harvest. Several hundred acres of cover disappears in an afternoon and everything living in it has to be somewhere warm by dark — and your house is the nearest warm thing. It is not sanitation and it is not something you did. Seal the house in August, before the combines run, and the whole autumn goes differently.
We suddenly have moths all through the house. Where are they from?
Almost always a bag in the garage or mud room — birdseed, dog food, chicken feed, corn for the deer, grass seed. Indian meal moths and grain beetles arrive in the sack, not through a window. We check the garage and pantry before treating anything outside, because that is where these are actually solved. Storing that stuff in sealed hard containers prevents nearly all of it.
What are the flies coming up the sunny side of the house in October?
Cluster flies. Their larvae parasitize earthworms in sod and pasture ground, so they are a rural insect specifically and have nothing to do with sanitation. They warm on south and west walls on sunny autumn afternoons and work into attics and upper windows. Sealing and treating those elevations ahead of the season is what works.
My house is from the 1800s. Can a stone foundation even be sealed?
Yes. You do not repoint the whole wall — you find the actual openings, usually a handful of spots at the sill line, around service penetrations and below grade, and pack them with copper mesh and steel wool before sealing over. It is detail work rather than masonry work, and country and village properties are usually easier than city ones because there is more clearance to work in.
I am buying a place in the country. What should the WDI inspection cover?
Tell us up front which structures you want in scope. The $99 WDI inspection on the NPMA-33 form covers what you specify — a detached garage, shed or barn is not automatically included, and on country properties those are often where the finding is. Sorting it out beforehand avoids an argument at closing.
Do you handle raccoons, groundhogs or bats?
No. We stop at rats and mice. Anything larger needs a licensed wildlife control operator, and we will tell you that and point you toward one rather than take the job.
What does pest control cost in Darke County?
One-time treatments start at $129 for common pests and $199 for the harder ones. WDI inspections are a flat $99. The Protection Plan runs about $63 a month bundled. Exclusion work is quoted after we look at your house. No distance surcharge, however far out you are.
