The short version
Rodent control in Georgia depends on which of the state's three rodents you have. UGA Extension confirms house mice, Norway rats and roof rats all live here: roof rats climb and enter at the roofline, while house mice and Norway rats come in low as winter lows near 33F push them indoors each fall. Every plan starts with sealing gaps of a quarter inch or more.
- Georgia has all three: house mice, Norway rats and roof rats, per UGA Extension.
- Trapping removes what is inside; sealing decides whether more arrive.
- A pencil-width gap is a doorway for a house mouse.
- Wet droppings with disinfectant before cleanup and never sweep them.
- Insist on a written entry-point list, not just a monthly trap service.
It is also for people who trapped a few mice last winter, thought it was handled, and are hearing the same noises again this year. For homeowners who found droppings under the sink, landlords fielding a tenant complaint, and anyone running a kitchen or stockroom where a health inspection is on the calendar. That repeat pattern is the clearest sign that sealing was skipped.
What to look for
The animals that fed outdoors all summer test your foundation, crawl space and roof edge for warmth, and whatever gap they find becomes the route they use for years. Then median winter lows around 33F take that away. Median summer highs near 89F with humidity around 71 percent and roughly 52 inches of rain a year mean lush vegetation and easy outdoor living from March into October. The climate splits the state. Roof rats climb, entering at soffits and rooflines, and UGA Extension confirms they live in Georgia alongside the other two. Norway rats dig burrows in soil against foundations, under sheds and near garbage storage, then work their way in through crawl space vents and utility penetrations, and a Norway rat may spend its whole life in a circle 100 to 150 feet across. House mice nest inside walls, behind cabinets and under appliances, and a colony can complete its whole life cycle without ever stepping outside; UGA Extension notes they seldom stray more than 5 to 10 feet from a wall. Three rodents matter here.
- 1Rice-grain droppings in a silverware drawer or along the back of a pantry shelf.
- 2Gnawed corners on cereal boxes and pet food bags.
- 3A crawl space vent screen torn open at one corner.
- 4Skittering inside a wall when you knock on it at night.
- 5Nests of shredded paper and insulation behind a water heater or dryer.
- 6Fresh soil pushed out of a hole near the foundation or a shed skirt.
- 7A stale, musky odor in a closed room that returns after you air it out.
Why it’s worth acting soon
- Mice can have litters about every 30 days from two months old, per UGA Extension, so waiting a season multiplies the work.
- Gnawed wiring in walls and crawl spaces creates a fire hazard.
- Contaminated food and prep surfaces put a household or a kitchen at risk.
- Leptospirosis, salmonellosis and rat-bite fever appear on the CDC list of illnesses rodents spread directly.
- Soaked and matted insulation stops performing and has to be replaced.
- Every extra month means more droppings to clean and more damage to repair.
Treatment options and typical costs
Exclusion sealing
Quoted after inspection
The building is closed from the crawl space to the roof edge using hardware cloth, metal flashing, steel wool behind sealant and repaired vent screens. Sealing is the only step that changes next winter, because it removes the routes the population depends on rather than reducing its numbers for a while.
- Time
- Depends on how many openings are found
- Best for
- Anyone who has dealt with rodents more than one season
Interior trapping
Quoted after inspection
Snap traps and multi-catch stations go on runways behind appliances, along baseboards and in the crawl space, then get checked and repositioned over several visits. The count matters: too few traps drag the job out, and UGA Extension suggests about a dozen per house for rats, set perpendicular to walls. Ask how many visits the price covers and what triggers an added charge.
- Time
- Until captures stop across several visits
- Best for
- Clearing mice already living in the structure
Exterior rat management
Quoted after inspection
For Norway rats, the work happens outside: locating and collapsing burrows, tightening trash storage, clearing ground cover against the foundation and placing secured stations along travel routes. Ask what product goes in the station, how it is anchored, and how nontarget animals are kept out.
- Time
- Recurring service while burrows persist
- Best for
- Rat activity at ground level around a home or business
Decontamination and insulation work
Quoted after inspection
Soiled material comes out, surfaces are disinfected and new insulation goes in. Follow the CDC method: air the space out for half an hour, saturate droppings with a bleach mix of about 1.5 cups per gallon, wait five minutes, then wipe rather than sweep.
- Time
- Depends on the space and contamination
- Best for
- Crawl spaces and attics with built-up droppings
Prices are typical published ranges. Ask what’s included before you compare quotes.
Clutter gives mice cover. Keeping stored fabric in lidded bins and off the floor takes away the nesting spots they like best.Roofline or crawl space: which Georgia rodent problem do you have?
With median winter lows near 33F, the arrival is a wave: the animals feeding outdoors through a warm, wet summer test the crawl space vents, garage door gaps and utility penetrations as soon as nights turn. There the inspection starts at grade and under the house. Plenty of Georgia properties see both. If you have noise overhead and droppings in a crawl space, treat it as two jobs on one building and make sure the quote covers both elevations. The single most useful question in Georgia is whether the activity is high or low in the building, because it points to the species and the entry points. UGA Extension confirms all three commensal rodents live in the state. Roof rats climb and can stay active through mild winters. They climb fence lines, cables and tree limbs, enter at soffits and roof-to-wall junctions, and nest above ceilings. Inspections there start on a ladder, and the sealing work is metal flashing and hardware cloth at height. House mice and Norway rats work at ground level, and their pressure is seasonal.
A rodent calendar for Georgia homeowners.
October through December is the arrival. Cold nights push mice and rats against the structure, and the first indoor droppings appear. January and February are the expensive months, because by then nests are established in insulation and the job includes cleanup as well as exclusion. If you act once a year, act in late summer. Spring is when Norway rats extend burrows. Soft, rain-fed ground makes digging easy, and a burrow started in March beside a shed can be a colony by August. Walk your foundation and shed skirt in early spring and mark every hole in the soil before ground cover fills in. Summer is deceptive. Warm nights near 89F daytime highs and abundant outdoor food keep the animals outside and quiet, so people assume they do not have a problem. This is the best window in Georgia to seal: crawl spaces are dry, roof work is manageable early in the day, and you are closing the building before anything needs to get in.
This is what a proper seal looks like: metal mesh fastened with screws and sealed at the edges. Foam or caulk on its own gets chewed through.What a good first inspection includes.
Under the house or in the attic, they should be looking for droppings clustered along joists, rub marks on framing, tunneling in insulation, chewed wire and daylight at a seam. Inside, the check runs behind the range and refrigerator, under sinks and in the pantry. The output is what counts. You want a written list naming each opening, its location and the material used to close it, plus a separate line for any decontamination. A quote that offers a monthly service and a trap count without that list has not diagnosed anything. Ask too whether someone returns to verify the seal after trapping ends. A first visit worth paying for is an examination, not a treatment. Outside, the inspector should walk the full perimeter looking at the foundation line, crawl space vents and access door, dryer and bathroom exhaust terminations, hose bibs, the garage door seal and every point where a pipe or cable enters. Soil disturbance near sheds and trash storage gets checked for burrows.
Why trapping alone keeps failing.
The fix is order of operations. Seal first or seal alongside trapping, then keep trapping until captures stop, then verify. In Georgia that means exterior sealing work followed by monitoring inside until captures stop. Judge a provider by whether they insist on that sequence rather than by how many traps they set on day one. Almost everyone starts with traps, and traps work: they remove the animals in the building right now. The trouble is that removal creates a vacancy rather than a barrier. House mice breed repeatedly through the year and can live entirely indoors, so a population that survives in a wall void rebuilds between your inspections. Norway rats forage well away from the nest, which means the burrow outside keeps supplying replacements even when your indoor catch rate drops to zero. What you experience is a quiet month followed by the same noises, and the natural conclusion is that the traps stopped working. They did not; the door stayed open.
How to read two rodent quotes side by side.
Trapping is never a one-visit job, so find the number of included returns and what happens after them. A low headline price often hides billed follow-ups. Third, cleanup. Removing soiled insulation, disinfecting and reinstalling is frequently a separate scope. Ask directly whether it is in or out, because it can be the largest single line. Fourth, the callback terms. If the company promises to return when animals get back in, ask how long that promise runs, whether it covers newly discovered openings, and whether it requires an ongoing service plan to stay in effect. Then get the final version in writing after an inspection, not over the phone, and compare scopes rather than prices. Put the proposals next to each other and ignore the totals until you have compared four things. First, the entry-point list. One quote will name specific openings and materials; the other will describe general service. The itemized one came from an actual inspection and is the only one you can hold anyone to. Second, visit count.
What affects the price
- Whether activity sits in one room or has reached the crawl space, walls and attic.
- How many entry points the inspection turns up and where they sit on the building.
- Whether the house has an open crawl space, which adds sealing surface.
- If contaminated insulation removal and replacement is inside the quote or outside it.
- The number of return trapping visits included before follow-ups are billed.
- Whether the company returns if animals get back in, and what conditions apply.
- Distance from the provider, which can affect how many follow-ups they will schedule.

What is your biggest concern about rodent control?
When to call for help
And if a rat has died somewhere you cannot reach, or the insulation is visibly fouled, hand the removal and cleanup to someone equipped for it. Crawl space work is another good reason to call, since finding gaps means going under the house on your back with a light and knowing what a rodent runway looks like. Those all point to a population living in structural voids rather than one animal that wandered in. Get help when you are catching mice week after week without the numbers dropping, when droppings show up on more than one floor, or when you can hear movement above a ceiling.
What you can do yourself
Do the traps and the housekeeping yourself, and bring in help for the sealing and the burrow work. Rats add a second problem, because the outdoor burrow keeps feeding the building no matter what you do indoors. Missing one keeps the door open. In a Georgia house with a vented crawl space and a long roof edge, the gaps that matter are behind ductwork, above a soffit return and where a plumbing line passes through a sill plate. The part that beats most homeowners is completeness. Screening a crawl space vent and fitting a door sweep are afternoon jobs with lasting value. Setting a dozen snap traps against walls where droppings appear, checking them daily, and moving pantry goods into hard containers will end a light mouse problem in a single-family home. There is real ground for do-it-yourself here.
Where you live matters
Georgia's cities in our data, from Atlanta, Augusta and Columbus to Macon and Savannah, all sit in a subtropical zone. Median summer highs of about 89F, humidity near 71 percent and roughly 52 inches of rain a year give rodents a long, easy outdoor season across the whole state. What changes is the winter. Median lows near 33F bring a genuine cold-weather push indoors for house mice and Norway rats, while roof rats, which UGA Extension confirms live in Georgia, work the rooflines and can stay active through mild spells. With a median home value around $345,000 in the cities we track, the damage from chewed wiring and ruined insulation is worth heading off. The practical rule for Georgia is to inspect both the roofline and the foundation and crawl space, then seal before October.
Simple ways to keep rodents away
- Fit metal sweeps to garage, basement and porch doors before the first cold week.
- Re-screen crawl space and foundation vents with quarter-inch hardware cloth.
- Pack steel wool behind sealant where water, gas and cable lines enter.
- Move firewood off the ground and away from the wall of the house.
- Cut ivy, dense groundcover and shrubs back from the foundation line.
- Keep pet food, birdseed and grass seed in hard containers with lids.
- Trim limbs so nothing overhangs the roof, which matters most where roof rats are active.
- Fix dripping hose bibs and slow gutters, since rats need daily water.
In a multi-unit building, mice move between apartments through shared walls and pipe chases, so treating one unit rarely solves it. Ask for a building-wide plan.Did you know?
UGA Extension notes that mice seldom travel more than 5 to 10 feet from a wall, which is why traps go perpendicular to the baseboard.
Human plague in the United States averages about seven cases a year, nearly all in the Southwest and Far West.
Rodent fleas, not the rodents alone, are the vector behind plague transmission to people.
Questions people ask
When do rodents come indoors in Georgia?
Roof rats are the exception: in mild weather they may never leave the attic at all. Sealing in late summer heads off most of it. The push begins with the first sustained cold nights, usually October into December, as median winter lows across Georgia settle near 33F.
Do I have mice or rats?
Sound helps too: mice make light scratching in walls, while rats make heavier, slower movement, often overhead. The species changes where the sealing work has to happen. Droppings tell you fast. Mouse droppings are about the size of a rice grain with pointed ends; rat droppings run a half inch or longer and are thicker.
How small a hole do I have to close in a Georgia home?
That is the standard because a house mouse can pass through it, and a rat will chew a smaller opening until it fits. Use metal at that size rather than expanding foam or caulk, both of which rodents gnaw straight through. About a quarter inch: the CDC likens it to a pencil's width, and UGA Extension says rodents get through openings as small as a dime.
Is bait a reasonable substitute for sealing?
It also raises the odds of a rodent dying inside a wall in a Georgia summer, which is an odor problem you will not forget. Use bait, if at all, as an outdoor supplement to sealing and trapping. Not on its own. Bait lowers the number of animals present but leaves every entry point open, so the space refills.
What is the safe way to clean droppings out of a crawl space?
Then wet the droppings with a bleach solution of roughly 1.5 cups per gallon of water, let it soak five minutes, and pick everything up with paper towels while wearing gloves. The CDC warns against sweeping or vacuuming, which lifts particles into the air you breathe. Ventilate the area for 30 minutes before entering.
How fast will a rat problem grow if I leave it?
UC IPM reports that a Norway rat produces four to six litters a year and weans 20 or more young. With about 52 inches of rain a year keeping Georgia yards green and soft, a single burrow behind a shed in spring can support a visible group by the time the weather turns. Fast enough to matter within one season.
My landlord says it is my housekeeping. Is it?
Sealing gaps in a foundation, sill plate or roof edge is a repair to the structure. Report the problem in writing with photos and dates, keep your own food in sealed containers, and ask specifically for an inspection that lists entry points. Housekeeping affects how attractive a building is, but it does not create the hole rodents use.
