Clark County farms harder than any county we serve. Eighty-nine percent of it — roughly 164,000 acres — is in active agricultural production, and the county has led the state of Ohio in yield per acre in corn, soybeans and wheat. That single fact drives more of the pest pressure here than anything else, and it is the reason a Clark County autumn does not look like a Kettering autumn.
Searching Clark County exterminator and searching Clark County pest control turn up the same thing here. One is the old name for the other.
We work the whole county out of our office at 733 Salem Ave in Dayton — about half an hour down US 40 or I-70. Not a franchise territory, not a call center that dispatches whoever is closest. The same licensed company, the same technician, the same phone number.
Every Clark County community, by name
Clark County held 136,001 people at the 2020 census, spread across two cities, eight villages, ten townships and a great deal of open ground. We serve all of it:
- Cities: Springfield and New Carlisle
- Villages: Enon, South Charleston, South Vienna, Tremont City, North Hampton, Donnelsville, Catawba and Clifton
- Townships: Bethel, German, Green, Harmony, Mad River, Madison, Moorefield, Pike, Pleasant and Springfield
- Communities and crossroads: Medway, Park Layne, Crystal Lakes, Green Meadows, Holiday Valley, Northridge, Lawrenceville, Pitchin, Vienna, Harmony, Brighton, Plattsburg, Selma, Bowlusville, Dialton and the farm ground between them
If your address is in Clark County and it is not on that list, it is still covered. Call (937) 569-3330 and we will tell you honestly whether we can get to you.
What 164,000 farmed acres does to a house in October
Here is the mechanic, because most people have never had it explained.
A field of standing corn or soybeans is habitat. It holds cover, seed, insects and a stable microclimate, and an enormous population of mice, voles, ground beetles, stink bugs and boxelder bugs lives in it all summer without ever coming near a house. Then the combines run.
Harvest does not gradually reduce that habitat. It removes it in an afternoon. Several hundred acres of cover becomes bare dirt between breakfast and dark, and every animal living in it has to be somewhere else by nightfall. What they move toward is the nearest structure with a warm wall and a gap — which, on a Clark County section road, is your house, your barn, your garage or your grain bin.
This is why the single busiest stretch of our Clark County year is late September through early November, and why it is sharper here than in the suburban counties. In Kettering, fall invaders trickle in. In Pleasant Township, they arrive the week the field next to you comes off.
The practical consequence: in Clark County, exclusion work should be finished before harvest, not started after it. Sealing the gaps in August is a different job — and a far cheaper one — than treating an established population in November. If you live with a field on any side of you, that is the single most useful sentence on this page.
The animals that make the move are predictable: mice and the occasional rat, brown marmorated stink bugs, Asian lady beetles, boxelder bugs and the cluster flies that follow earthworms in pasture ground. None of them are a hygiene problem. All of them are a construction problem, which is why we treat them as one.
Three waters, and why they matter separately
Clark County is unusual in that it drains three different ways, and each one produces a different call.
The Mad River comes down the western side of the county past Tremont City, Donnelsville, Enon and Medway before it leaves for Dayton. It is a cold, fast, spring-fed river sitting on gravel, and the land beside it is terrace ground — well drained, sandy, and full of the burrowing insects that like that soil. Ant pressure along the Mad River corridor is genuinely higher than it is on the clay in the east of the county, and the species mix skews toward pavement ants and the citronella ants that alarm people every spring by swarming out of a basement crack.
Buck Creek runs through the middle of Springfield and is held back at the top end by C.J. Brown Dam, finished in 1973 after the city spent four decades arguing about the 1924 flood. The reservoir is 1,970 surface acres of standing water on the northeast corner of the county. It is a fine thing to live near and it is, in July, a very large mosquito habitat. Mosquito work on that side of Springfield starts earlier and focuses on breeding sites rather than fogging.
The Little Miami rises in the southeast of the county, near Clifton, and cuts the gorge on its way out. That is limestone country with genuine rock outcrop, and rock outcrop means camel crickets, springtails, house centipedes and the damp-loving insects that come with a cool, wet basement. A Clifton basement and a South Vienna basement are not the same building problem.
Springfield: the county seat and the old housing stock
Springfield holds most of the county’s people and nearly all of its oldest buildings. It was platted in 1801, the National Road arrived in 1839, the railroads came in the 1840s, and the agricultural-equipment money built houses fast between roughly 1870 and 1930.
That date range is the whole story for a technician. Houses from that era are balloon-framed — the studs run uninterrupted from sill plate to roofline with no fire blocking between floors — so a mouse that enters a Springfield foundation in October uses the stud bay as a vertical highway and turns up in a second-floor closet in November. The foundations are stone or rubble as often as poured concrete, and stone foundations move, so the mortar joints open.
You do not solve that with a spray. You solve it with exclusion — sealing the actual openings with material a rodent cannot chew. We have written the whole picture up on our Springfield pest control page, including the student-rental bed bug cycle around Wittenberg and the warehouse and dock-door work along the National Road.
New Carlisle, Medway and the Bethel Township edge
New Carlisle sits in the southwest corner of the county and does not behave like the rest of it. It was laid out in 1810 as York, incorporated as a village in 1831, became a city in 1973, and now holds around 5,800 people. Locally it is still remembered for the June 1933 robbery of the New Carlisle National Bank by John Dillinger.
What makes New Carlisle, Medway, Park Layne and Crystal Lakes different from Springfield is who lives there. This corner runs on Wright-Patterson Air Force Base, which means a lot of the housing turns over on a military rotation rather than a local one — PCS orders, base housing waiting lists, tenants who arrive with everything they own in a truck that has been in four other states.
That produces two specific patterns. The first is bed bugs moving on furniture at a higher rate than the surrounding countryside would predict, because turnover is when bed bugs travel. The second is short-notice service — a family reporting for duty in eleven days needs a treatment scheduled this week, not a slot in a month, and a landlord needs a unit clear before the next tenant signs. We schedule that corner of the county accordingly.
The housing stock itself is mostly post-war ranch and split-level on crawl spaces and slabs. Crawl-space ventilation and moisture are the recurring finding there — a damp crawl under a 1960s ranch supports the whole moisture-pest complex and, over enough years, the conditions that interest subterranean termites.
Enon, the mound, and the Mad River terrace
Enon sits on the Mad River terrace between Springfield and Fairborn, and it has something almost no other village in Ohio has: the Knob Prairie Mound, an Adena conical burial mound that covers better than an acre, runs 574 feet around and stands about forty feet high. It is the second largest conical mound in the state. Charles Beaver bought the ground in 1952 and deeded the mound to the village in 1953, which is why it is still there instead of under a subdivision.
The mound is not a pest problem. The soil it sits on is the point. Enon is built on the same well-drained terrace gravel the Adena chose, and that soil drains fast, warms early and supports heavy ant and ground-nesting wasp activity. Enon calls skew toward ants in April and toward yellowjackets and ground nests in August — the ones people find with a lawnmower, which is the worst way to find them.
Enon and Mad River Township also carry the county’s heaviest carpenter bee load, for a simple reason: a lot of cedar and redwood decking went onto those houses in the 1980s and 1990s, and carpenter bees prefer soft, unpainted, weathered softwood. A deck rail that has been drilled for fifteen seasons is structurally compromised, not just ugly, and woodpeckers finish what the bees start.
South Charleston, Catawba, South Vienna and the eastern grain towns
The eastern half of the county is the agricultural half, and its villages are grain towns — laid out on the roads, built around an elevator and a rail siding, surrounded on all four sides by production ground.
South Charleston was platted on the first of November, 1815, named for its first merchant Charles Paist, and held 1,706 people at the 2020 census. It still has its opera house. South Vienna sits up on the National Road in Harmony Township. Catawba is smaller again, out toward the Champaign County line.
Grain towns have a pest profile of their own, and it is worth stating plainly because most companies will not:
- An elevator is a permanent food source. Anywhere grain is stored at scale, you have a resident rodent population that is not going away, and the realistic goal for a house nearby is not eradication of the neighborhood — it is keeping your building sealed and unattractive. We will tell you that up front rather than sell you a treatment that cannot deliver.
- Stored-product insects come in with feed. Indian meal moths, sawtoothed grain beetles and weevils arrive in a bag of birdseed, dog food or livestock feed from the co-op, not through a window. Nearly every one of these calls is solved in the pantry or the feed room rather than on the exterior.
- Cluster flies come off pasture, not garbage. Their larvae parasitize earthworms in sod ground, so they are a rural insect specifically. They come up the sunny south and west walls on warm October afternoons and get into attics and upper-story windows. A homeowner who thinks they have a sanitation problem is looking at the wrong cause entirely.
- Barn spiders and the outbuilding complex. Where there are outbuildings there are spiders, and most of what people find is harmless — but our guide to the two Ohio spiders that actually matter is worth two minutes if you are reaching into a woodpile.
Tremont City, North Hampton, Donnelsville and Clifton
The small villages in the north and west of the county — Tremont City, North Hampton, Donnelsville, Lawrenceville, Bowlusville — are old, small and built close to the road, with a mix of nineteenth-century frame houses and post-war infill. The nineteenth-century half has the stone-foundation and balloon-frame problem Springfield has, at a smaller scale and usually with more ground clearance around it, which makes exclusion work easier and cheaper here than it is downtown.
Clifton is its own case. The village straddles the Clark and Greene county line at the head of the Little Miami gorge, and the Historic Clifton Mill — first built on that site in 1802 by Owen Davis, a Revolutionary War soldier — is one of the largest water-powered gristmills still standing anywhere. Clifton is limestone, rock outcrop, deep shade and constant humidity. That combination produces the damp-basement insect complex year round rather than seasonally, and it is the one corner of the county where we expect to find rodent entry through rock rather than through framing.
The Clark County pest calendar
Clark County runs a few days behind Dayton proper on elevation, and its autumn is governed by the combine rather than the thermometer. Here is the working year:
- March and April. Overwintered stink bugs, Asian lady beetles and boxelder bugs wake up inside the wall and come out at the windows. They did not just get in — they have been in that wall since October, which is the single most common misunderstanding we correct. Ants begin moving, and the citronella ant swarm out of a basement crack starts the phone ringing.
- May and June. Termite swarm season. This is the window where somebody finds a pile of discarded wings on a windowsill and needs to know quickly what they are looking at — the difference between termites and flying ants is in the waist, the wings and the antennae, and it decides whether you have a nuisance or a structural problem. Carpenter bees start drilling soffits and deck rails.
- July and August. Peak mosquito along Buck Creek, the Mad River and C.J. Brown. Wasp and hornet nests reach the size people notice. Yellowjackets turn aggressive late in this window as the colony’s food supply shifts, and ground nests in lawns become the most common sting call of the year. This is also the window to do exclusion work, ahead of harvest.
- September through early November. The busiest stretch of the Clark County year, and it is driven by harvest rather than by frost. Fields come off, cover disappears, and everything living in 164,000 acres of it needs somewhere else to be. Fall invaders press the south and west elevations of every house on a sunny October afternoon; mice move indoors in numbers.
- November through February. Rodents are inside 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 in the spring. This is also the best window to see entry points, because the vegetation is down and the sight lines are clear.
The base, the airport and the I-70 corridor
Commercial pest work in Clark County concentrates in three places, and they are not the same job.
Springfield-Beckley. The municipal airport sits about five miles south of the city and hosts Springfield Air National Guard Base, home of the 178th Wing on roughly 114 acres of leased ground, with an intelligence, surveillance and reconnaissance mission and Space Force intelligence units now arriving. Airfield-adjacent buildings sit in open mown grass surrounded by crop ground, which is close to the ideal habitat for voles, field mice and ground-nesting wasps. Hangars and maintenance buildings have large doors that spend the day open, and nothing you do inside a hangar substitutes for managing the perimeter.
The I-70 and US 40 distribution corridor. Springfield sits on the interstate between Dayton and Columbus, and warehouse and logistics space has followed. Dock doors are the single largest structural liability in any warehouse in this county — a dock seal torn at the corner is a permanent open door for rodents and for the flies that follow the trash line. Rail-adjacent buildings carry Norway rat pressure that suburban buildings simply do not.
Food handling and hospitality. For restaurants, groceries, schools and care facilities, the documentation matters as much as the treatment. A health inspector wants a service log, a pest sighting register and evidence of a scheduled program — not a can of spray under a sink. Our commercial pest control program produces that paperwork as a matter of course, and every application is recorded with the product, the EPA registration number, the rate and the licensed applicator, because Ohio requires it and because it is the record that protects you in an inspection.
Living next to the fields: what changes for your house
Most Clark County homes have crop ground on at least one side, and that proximity changes a few practical things about the house itself. None of them are about how clean you keep it.
- The perimeter does most of the work. With open ground beside you there is no neighboring house acting as a buffer, so pressure arrives at your foundation directly. A treated, maintained exterior perimeter accomplishes far more here than interior work does.
- The garage is the front line. It is the least sealed part of most rural and edge-of-town houses. A door seal that no longer meets the slab at the corners is the most common rodent entry we find, and the garage is usually where the pet food, birdseed and grass seed live too.
- Pantry moths come from a bag, not a window. Indian meal moths and grain beetles arrive in birdseed, dog food, chicken feed or a sack of deer corn and spread from the garage or mud room. We check there before treating anything outside, because that is where these are actually solved. Sealed hard containers prevent nearly all of it.
- Outbuildings need a decision. A shed or detached garage is harborage, and it is worth being deliberate about whether it is in scope. We will tell you honestly when treating one will change things for the house and when it will not.
And the timing point is worth repeating, because it is the single most useful thing on this page: seal the house in August, ahead of harvest. The same work costs less and accomplishes more done before the fields come off than after the mice are already inside.
For the county’s landlords, boards and institutions
Clark County has a large rental base — the Wittenberg ring in Springfield, the military turnover in the New Carlisle and Medway corner, and single-family rentals scattered through every township. Three things matter to an owner here.
Bed bugs are a building problem, not a unit problem. In a balloon-framed Springfield house cut into four units, bed bugs travel the wall voids and the plumbing chases and move floor to floor. Treating the unit that complained and stopping there is how a building ends up with three involved units by the following semester. We inspect the neighbors on all six sides of an involved unit as a matter of routine.
German cockroaches arrive in belongings. They are not an outdoor insect that wanders in — they come in cardboard, in used appliances, in a microwave carried from a previous apartment. In shared-wall buildings they become a building-wide issue quickly. We use gel bait rotation and insect growth regulators rather than the foggers that scatter a population deeper into the structure; here is why bug bombs make roach problems worse.
Per-door pricing and documentation. Owners with multiple units can put them on our per-door property manager program, which gets scheduled service, priority response and the paper trail that matters when a tenant dispute or a housing inspection arrives.
What we do not do
We stop at rats and mice. We do not handle raccoons, groundhogs, opossums, skunks, squirrels or bats, and in a county with this much open ground and this many outbuildings, that call comes in regularly. Anything larger than a rat needs a licensed wildlife control operator, and we will tell you that and point you at one rather than take a job we are not the right company for.
We also will not sell a recurring plan to somebody who needs one treatment, and we will say so when the honest answer is that the problem is a construction defect rather than an insect population.
Real estate, WDI inspections and the age of the housing
Clark County has a lot of old housing and a lot of rural property, and both raise the stakes on a wood-destroying insect inspection.
We run termite and WDI inspections at a flat $99, reported on the NPMA-33 form your lender is expecting, with next-business-day scheduling for realtors. On a Springfield house from the 1890s with a stone foundation, or on a farmhouse with a porch that has been rebuilt twice, that inspection is worth having whether or not the lender demands it — the questions that matter are old damage versus active infestation, and whether the sill plate is sound where you cannot see it.
Two things worth knowing before you order one. First, a WDI report covers wood-destroying insects — subterranean termites, carpenter ants, powderpost beetles, carpenter bees — and it is an inspection, not a warranty. Second, in a county where a good many properties include outbuildings, be clear with your inspector about what structures are in scope, because a barn is not automatically included and a barn is frequently where the finding is.
What it costs in Clark County
Same pricing as everywhere else we work. We do not charge a distance premium for Clark County, and we quote before we treat.
- One-time treatment, common pests: from $129 — ants, spiders, roaches, wasps, mice
- One-time treatment, harder pests: from $199 — the jobs that need more material, more time or a return visit
- 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
The re-treatment guarantee is part of the Protection Plan: while you are on the plan, if a covered pest comes back between scheduled visits, we come back and re-treat at no additional charge. That guarantee is a feature of the plan rather than of every one-time job, and we would rather say so plainly here than have you find out later. Full detail is on our pricing page.
What the sixth county adds
We started in Montgomery and Greene, added Miami, Warren and Preble, and Clark came in alongside Butler and Darke to make eight. Clark is the one that changed the shape of the business most, and it is worth saying why.
The suburban counties gave us houses. Clark gave us ground — 164,000 farmed acres, grain elevators, machine sheds, an airfield in a crop field, and a fall invasion that runs on the combine schedule. Working here has made us better at the rural end of this trade, and that knowledge travels: what we learned about perimeter bait rings and pre-harvest exclusion in Pleasant Township is exactly what a property in western Preble County or northern Darke County needs.
It also joined our two ends together. Springfield to Eaton is a long way across, but the middle of it is one continuous problem — old housing on stone foundations, surrounded by production agriculture, drained by rivers that flooded once and got engineered afterward. Clark County is where that pattern is clearest.
Our full territory: Montgomery, Greene, Miami, Clark, Warren, Butler, Preble and Darke counties. The rest of it is mapped on our service areas page.
The other two newcomers. Clark joined our territory alongside Butler County and Darke County to take us from five counties to eight. Clark taught us crop agriculture and the combine-driven autumn; Darke taught us animal agriculture, where the pressure never lets up; and Butler, the largest of the three at 390,357 people, taught us to run four different programs in one county in the same week.
Clark County, town by town
Deeper guides to how this plays out where you actually live:
- Springfield — the county seat: balloon framing, Buck Creek, and the student-rental cycle around Wittenberg.
- New Carlisle — the Wright-Patterson corner: bed bugs and fleas on the military turnover cycle, and short-notice scheduling.
- Enon — Mad River terrace gravel: heavier ant pressure, yellowjacket ground nests and carpenter bees in 1980s decking.
- South Charleston — a grain town’s calendar: the harvest push, the elevator, and honest expectations.
Frequently asked questions
Do you cover all of Clark County, or just Springfield?
All of it. Springfield, New Carlisle, Enon, South Charleston, South Vienna, Tremont City, North Hampton, Donnelsville, Catawba, Clifton, Medway, Park Layne, Crystal Lakes and every township in between, including addresses on open farm ground. We run the county out of our Dayton office at 733 Salem Ave and there is no distance surcharge.
Why does my Clark County house get overrun every fall when my sister’s house in Kettering does not?
Because eighty-nine percent of the county is farmed. When several hundred acres of corn or beans comes off in an afternoon, everything living in that cover has to relocate by dark, and the nearest warm wall is yours. It is not a sanitation issue and it is not something you did. The fix is exclusion — sealing the openings — and it works far better done in August than in November.
When should I schedule exclusion work?
July or August, before harvest. Sealing gaps ahead of the fall movement is a straightforward job. Treating an established indoor population in November is a longer and more expensive one. If you have a field on any side of you, this is the most useful thing on this page.
What does pest control cost in Clark County?
One-time treatments start at $129 for common pests and $199 for the harder ones. Termite and WDI inspections are a flat $99. The Protection Plan runs about $63 a month bundled. We quote before we treat and the quote is the price.
Is the re-treatment guarantee on every job?
No — it 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 extra charge. One-time treatments are quoted as one-time treatments. We would rather be straight about that here than have you discover it later.
Do you work on farms, barns and grain bins?
Yes, and it is a normal account for us here. Farmsteads get a mapped perimeter bait ring rather than scattered interior placements, product selection that respects livestock and stored feed, a stored-product inspection in the feed room, and application records with the EPA registration number and applicator license on them.
Do you handle raccoons, groundhogs, squirrels 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 a job we are not the right company for.
How fast can you get to Clark County?
Usually the same week, often sooner. Stinging insects, rodents and bed bugs get priority scheduling because all three get materially worse while you wait. The New Carlisle and Medway corner also gets short-notice slots for military moves.
I am buying a house in Clark County. What do I need?
A $99 WDI inspection on the lender-ready NPMA-33 form. On this county’s older stock — stone foundations, balloon framing, porches that have been rebuilt — it is worth having whether or not your lender requires it. Tell us up front if outbuildings should be in scope, because a barn is not automatically included.
Are you actually licensed, and by whom?
Yes. Greater Dayton Pest & Rodent is licensed by the Ohio Department of Agriculture as a pesticide business, firm license #115079. Bryan Camden is the owner and commercial applicator, license #170858, in categories 10A, 10B and 12. Ask any company for those numbers before you let them treat your home.
The whole county, covered
Clark County is old houses on stone foundations surrounded by the most productive farm ground in Ohio, and that combination produces a specific set of problems on a specific schedule. They are solvable by somebody who knows the buildings and knows the calendar, rather than somebody reading off a route sheet.
