Scratching in the walls at night. Droppings behind the stove. A chewed bag of flour in the pantry. By the time you see one mouse, there are usually more — mice breed year-round indoors, and a pair can become dozens in a few months. Rodent work is in our name because it’s what we do best: we don’t just set traps, we find how they’re getting in and shut the door behind them.
Signs you have mice or rats
- Droppings along walls, in drawers, or under sinks — mouse droppings are rice-grain sized, rat droppings raisin-sized
- Scratching or skittering in walls and ceilings, especially at night
- Gnaw marks on food packaging, wood, or wiring — chewed wiring is a genuine fire risk
- A musky ammonia smell in closed spaces like cabinets or the garage
- Pets staring intently at walls or baseboards
Why hardware-store traps don’t solve it
A snap trap catches the mouse that found it. It does nothing about the gap under your garage door, the hole where the AC line enters the house, or the nest in the attic insulation. Around Dayton, mice push indoors hard from October through February — if the entry points stay open, next fall’s mice simply replace this fall’s. Treatment without exclusion is a subscription to the same problem.
Our rodent process
- Full-perimeter inspection — we walk the whole structure looking for entry points as small as a dime (mice) or a quarter (rats), plus the attic, basement, crawlspace, and garage.
- Knockdown — professional trapping and baiting placed where rodents actually travel, secured away from kids and pets.
- Exclusion — we seal entry points with rodent-proof materials: steel wool and sealant, hardware cloth, door sweeps. This is the step that makes the fix permanent.
- Verification — we confirm activity has stopped, and our re-treatment guarantee backs the work.
What it costs
Every rodent job starts with a free quote — the price depends on the level of activity and how much exclusion work your home needs, and we’ll give you the number before any work begins. No inspection fee, no surprises.
Rodent control FAQ
How do I know if it’s mice or rats?
Size of the droppings is the quickest tell — rice grain means mice, raisin means rats. Mice are far more common inside Dayton-area homes; rats show up more around older sewers, alleys, and outbuildings. Either way the process is the same: find the entry, remove the animals, seal the route.
How long does it take to get rid of mice?
Most homes see activity stop within one to two weeks of knockdown plus exclusion. Heavy, long-established infestations can take longer — we’ll tell you honestly what you’re dealing with after the inspection.
Will they just come back next winter?
Not through the holes we sealed. Exclusion is the difference between rodent control and rodent rental — and it’s backed by our re-treatment guarantee.
Do you do commercial rodent programs?
Yes — restaurants, warehouses, and rental properties on scheduled service. See our commercial pest control page.

Know your enemy: the rodents of the Miami Valley
Three rodents cause virtually every infestation we treat around Dayton, and telling them apart matters because they behave differently, travel differently, and require different control strategies. The house mouse is the most common by a wide margin — a two-to-four-inch gray-brown mouse that lives its entire life indoors once established, nesting in wall voids, attic insulation, stored boxes, and the insulation panels of appliances. House mice are curious explorers, which is why trapping works quickly on them when placement is right. They need almost no water, extracting what they need from crumbs and pantry food, and they reproduce at a pace that surprises most homeowners: a female can produce a litter of five to eight pups every three to four weeks, and those pups are themselves breeding within six weeks.
The deer mouse shows up on properties that border fields, woods, and creek corridors — which describes a huge share of the Miami Valley, from Bellbrook’s wooded lots to the farm edges of Greene County. Deer mice are two-toned (brown backs, white bellies and feet) and they typically invade garages, sheds, barns, crawlspaces, and vehicles rather than kitchen walls. They matter for a health reason: deer mice are the primary carrier of hantavirus. Cases in Ohio are rare, but the risk is exactly where homeowners encounter deer mouse droppings — sweeping out a shed or shop vac-ing a garage corner — which is why we handle droppings cleanup with wet-methods and HEPA equipment rather than dry sweeping.
The Norway rat is the Miami Valley’s only established rat, a heavy-bodied burrower that lives along sewer lines, riverbanks, alleys, and under concrete slabs and outbuildings. Rat pressure in our area concentrates in older Dayton neighborhoods with aging sewer laterals, around livestock and grain operations at the rural edges, and near dumpster corrals behind commercial strips. Rats are the opposite of mice behaviorally: deeply suspicious of new objects, which is why amateur trapping fails — a rat may avoid a new trap for a week or more. Successful rat work is patient work: pre-baiting, burrow identification, exterior bait stations, and above all, eliminating the food source that anchors the colony.
The Dayton rodent calendar: what happens when
January–February: populations that made it indoors in fall are now breeding in your walls. Activity noise peaks because outdoor food is scarce and every calorie in your kitchen matters. This is when most homeowners finally call — and the good news is that winter mice are highly trappable. March–April: as ground thaws, some pressure moves back outdoors; this is the smartest season for exclusion work, sealing entry points while populations are at their annual low. May–August: outdoor breeding season. Mice and rats multiply in brush piles, sheds, ivy beds, and burrows. What you do now — clearing harborage, securing bird seed and pet food, fixing that gap under the garage door — determines how bad October gets. September–November: the fall invasion. The first hard frosts push rodents indoors along foundation lines, and the whole Miami Valley’s call volume triples. A mouse needs a gap the width of a pencil; a rat needs about a quarter. December: stragglers keep probing for warmth around door thresholds and utility penetrations while established indoor populations settle into nesting sites near heat sources — furnace rooms, water heaters, and the warm side of kitchen appliances.
The ten entry points we find on almost every Dayton home
- Garage door corners and thresholds — the number-one entry in newer subdivisions; weatherstripping compresses and corners curl, leaving mouse-width gaps at both ends
- AC line set penetrations — the hole where refrigerant lines enter the house is almost never sealed properly by installers; the foam degrades in two summers
- Gas meter and utility penetrations — pipe penetrations through block and siding, often hidden behind the meter itself
- Sill plate gaps in older homes — pre-war Dayton, Oakwood, and Miamisburg homes settle, opening seams between stone or block foundations and the wood structure above
- Crawlspace vents and access doors — rusted screens and warped access panels are open doors
- Dryer vents and exhaust flappers — a stuck flapper is a heated tunnel straight into the laundry room
- Roofline gaps and construction joints — mice climb brick, siding corners, and downspouts; gaps where soffit meets fascia let them into attics
- Bulkhead and basement door thresholds — especially steel doors on older concrete that no longer meet square
- Under front porches and stoops — voids beneath concrete stoops shelter burrows with direct access to foundation cracks
- Attached-deck ledger boards — the deck attachment area often bridges directly into rim-joist gaps
What rodents actually cost you
The damage bill from a rodent infestation almost always exceeds the treatment bill. Rodents are compulsive gnawers — their incisors grow continuously and they wear them down on whatever is available, which in your house means electrical wiring, PEX water lines, HVAC flex duct, and structural wood. Chewed wiring is implicated in a meaningful share of unexplained house fires nationally, and we regularly open Dayton attics to find junction boxes surrounded by droppings and gnawed insulation on conductors. Insulation damage is the second cost: mice tunnel and nest in fiberglass and cellulose, compacting it and saturating it with urine, and a multi-year infestation can degrade an attic’s insulation value enough to show up on your utility bills. Then there’s contamination — a single mouse deposits fifty to seventy-five droppings a day, and everything in a pantry corner or under a sink where mice traffic has to be treated as contaminated. For families with asthma, mouse urinary proteins are a documented allergen and asthma trigger, particularly in kids.
Why our exclusion outlasts the hardware-store version
Most DIY exclusion fails for one of two reasons: wrong materials or wrong gaps. Expanding foam alone is a rodent snack — mice chew through it in a night. Steel wool alone rusts, shrinks, and falls out of vertical gaps within a season or two. What works is the combination we use: copper mesh or stainless steel wool packed into the gap as a gnaw-proof core, sealed over with polyurethane sealant that locks it in place and blocks the airflow that advertises the opening (rodents find entry points by following warm air currents leaking out of your house). For larger openings we cut and fasten galvanized hardware cloth; for garage doors we install rodent-rated threshold seals rather than standard rubber, because standard weatherstrip gets eaten. And because we do this every week, we find the gaps homeowners miss — we’re on our knees with a flashlight at the gas meter, not glancing at the front of the house.
Rodent-proofing checklist you can start today
- Store bird seed, grass seed, and pet food in steel or heavy plastic bins with locking lids — paper bags in the garage are the single biggest rodent magnet we see
- Keep firewood stacks at least a foot off the ground and away from the foundation
- Cut back ivy, juniper, and any ground cover touching the house — they’re covered highways
- Elevate garage storage onto shelving; floor-level cardboard is nesting habitat
- Fix dripping outdoor spigots — rats especially need a water source
- Don’t leave pet bowls out overnight, inside or out
- Compost in a sealed tumbler, never an open pile, and keep grill drip trays clean
- Check the garage door seal with a flashlight test at night: any light showing through is a gap a mouse can work with
More rodent questions we hear every week
Do ultrasonic repellers work?
No. Independent testing has repeatedly shown rodents habituate to ultrasonic devices within days, and we routinely trap mice living within a few feet of plugged-in repellers. Save the money and put it toward sealing the actual entry points.
We have a cat — why do we still have mice?
A good mouser suppresses the mice it can reach, but mice living in wall voids and attics never cross the cat’s territory. Worse, cat and dog food left in bowls feeds rodents overnight. Cats are companions, not exclusion programs.
Is rodent bait dangerous for my pets or the hawks in my yard?
Handled correctly, risk is low — and handling it correctly is the job. Any bait we use goes inside locked, anchored stations that pets and children physically cannot open, placed along rodent runways rather than open areas. Where secondary-exposure concerns are highest — properties with owls, hawks, or outdoor cats nearby — we shift the program toward trapping and exclusion instead. Tell us about your animals during the inspection; the plan adapts.
I saw one mouse. Is that really a big deal?
One daytime mouse sighting usually means an established population, because mice are nocturnal by preference and only forage in daylight when competition at night is heavy. Treat the first sighting as an early warning worth acting on — it is dramatically cheaper to solve at week one than month six.
How do you confirm the rodents are actually gone?
We use evidence, not vibes: monitoring stations with non-toxic census blocks, tracking-patch checks in dusty zones, fresh-versus-old dropping assessment, and a follow-up walkthrough of every previously active area. When two consecutive checks come back clean, we call it resolved — and the re-treatment guarantee stands behind that call.
Do you clean up droppings and contaminated insulation?
We handle dropping remediation in accessible areas as part of larger rodent jobs — wet-method disinfection and HEPA vacuuming, never dry sweeping, because dry sweeping aerosolizes exactly what you don’t want to breathe. For attics with widespread insulation damage we’ll document the damage for your insurance conversation and coordinate scope with an insulation contractor.
Attics, basements, and crawlspaces: where the real work happens
The rooms you live in are where you notice rodents; the spaces you rarely enter are where they actually live. In attics we look for insulation tunnels, packed nesting pockets in corners and around can lights, gnawed wire runs, and the greasy rub marks rodents leave along rafters they travel nightly. In basements the story is told at the sill plate — the seam where the foundation meets the framing — and around every pipe and cable that passes through it. Miami Valley crawlspaces add moisture to the equation: a damp crawl with fallen vapor barrier is five-star rodent habitat, offering water, cover, and untouched access to subfloor voids. Our inspections physically enter these spaces, because a rodent job scoped from the doorway is guesswork, and guesswork is how infestations come back.
Vehicles deserve a mention too. Every fall we take calls about mice nesting in engine bays and cabin air filters of cars parked in garages and near field edges — modern soy-based wire insulation is genuinely attractive to them, and rodent-chewed harnesses are an expensive repair. If your check-engine light coincides with mouse sightings in the garage, mention it during the inspection; treating the garage and sealing its exterior protects the car parked inside it.
For businesses, rodent control is documentation as much as elimination. Restaurants and food-handling facilities in Montgomery and Greene County get inspected against an expectation of monitoring stations, service records, and a named pest-control provider — showing an inspector a binder with dated service reports changes the tone of the visit. Our commercial rodent programs build that paper trail automatically: station maps, activity logs per visit, and trend notes so you can see pressure rising before it becomes a dining-room sighting. Warehouses along the I-70/75 logistics corridor get dock-door sweeps, exterior bait-station perimeters, and interior mechanical trapping that satisfies both auditors and the practical goal of never finding droppings on a pallet.
A last word on speed: rodent problems compound weekly, not monthly. Every week an entry point stays open, the population inside grows, the contamination spreads farther into insulation and storage, and the eventual exclusion-and-cleanup scope gets bigger. The pattern we see over and over across Dayton, Trotwood, and Huber Heights is a homeowner who heard scratching in October, bought traps in November, caught a few, assumed victory, and called us in February with a wall that smells and a pantry that keeps getting hit.
