Rodents in barns, camps and lake houses
A hay barn, a deer camp that sits empty until November, a lake house you open twice a year. Rodents love all three. Here is what it costs you, how to close a place up right, and how to clean up safely when you open it.

How do you keep rats and mice out of barns and hunting camps?
Take away the food, close the gaps and check often. Store feed and seed in metal bins with tight lids, keep a 3-foot strip around buildings clear of brush and junk, and seal openings around doors, feed augers, water lines and conduits. A mouse needs a gap of only about 1/4 inch and a rat about 1/2 inch. An adult rat eats 1 to 2 ounces of feed a day and spoils more than it eats, according to Mississippi State University Extension. For camps and lake houses that sit empty, remove all food before you leave, set snap traps in covered boxes, and when you come back, air the building out for 30 minutes and wet-clean droppings with disinfectant, as the CDC advises. Lafayette County has 378 farms on about 110,895 acres, per the 2022 Census of Agriculture.

Rodent problems by property type in Lafayette County
Farm numbers from the USDA 2022 Census of Agriculture; Sardis Lake visitors from the U.S. Army Corps of Engineers.
| Property | Main rodents | Biggest risk | First fix |
|---|---|---|---|
| Hay barn | Norway rats, house mice | Nests in bales, chewed wiring, fire risk | Clear perimeter, raise bales off the ground |
| Feed room | Norway rats, house mice | Feed loss and contamination | Metal bins with tight lids |
| Chicken coop | Norway rats | Eaten feed and eggs, killed chicks | Hardware cloth, close the coop at night |
| Hunting camp | Deer mice, house mice, cotton rats | Nests and droppings while empty | Remove food, seal gaps before leaving |
| Lake house | House mice, roof rats | Wiring, insulation and stored linens | Seal before the off-season |
| Shop and equipment shed | House mice, rats | Chewed wiring in tractors and trucks | Seal doors, check engine bays |
Feed loss math
What rodents cost in feed: the math
Feed numbers and population estimates from Mississippi State University Extension, Controlling Rodents on the Poultry Farm.
| Rodents | Feed eaten per year (at 2 oz a day) | What else they cost |
|---|---|---|
| 1 rat | About 46 pounds | USDA estimates feed waste and damage can reach $25 per rat a year |
| 10 rats | About 460 pounds | Spoiled feed, chewed sacks, droppings in troughs |
| 50 rats | About 2,300 pounds | Chewed wiring, insulation, burrows under slabs |
| 200 rats | About 4.6 tons | A level Mississippi State calls not a major infestation for a large poultry house |
Rats are mostly active at night, so the damage adds up before anyone sees one. Mississippi State University Extension uses a rough rule: for every rodent you see, there are 20 to 50 you do not.
Seeing rats in daylight usually means a large population, because the crowding pushes some out when the others are hiding.
- Signs but no rodents seen: roughly 1 to 100
- Occasional rats seen at night: roughly 100 to 500
- Rats seen nightly, sometimes by day: roughly 500 to 1,000
- Several seen during the day: up to 5,000
Camps and lake houses
Closing up and opening a hunting camp or lake house
Empty buildings are where deer mice and cotton rats move in.
Before you leave: food
Take every bit of food home, including pet food, birdseed and corn. Store anything left in metal or hard plastic with tight lids.
Before you leave: gaps
Seal gaps around pipes, vents and doors with steel wool, caulk and hardware cloth. Add door sweeps.
Before you leave: traps
Set snap traps in covered boxes along walls and in cabinets. Rodents that get in are caught instead of nesting.
When you return: air out
Open doors and windows and leave for 30 minutes before you start cleaning, as the CDC advises.
When you return: wet-clean
Gloves on. Spray droppings and nests with disinfectant or 1.5 cups of bleach per gallon of water, wait 5 minutes, wipe up.
When you return: check
Look for chewed wiring, nests in mattresses and linens, and droppings in drawers. Wash linens on hot.
Mississippi has reported no hantavirus cases since 1993, per the state health department, but deer mice are the main U.S. carrier. The full method is in our droppings cleanup guide.
Barns and feed rooms
Keeping rodents out of barns, feed rooms and coops
You will not seal a barn perfectly. You can make it a poor place to live.
Mississippi State University Extension is honest about barns: a farm building cannot be made completely rodent-proof. The goal is fewer ways in, less to eat and nowhere to hide, so the rodents that do get in are easy to catch.
Most of the work is cheap: metal bins, a clear strip around the building, and sealing the gaps where augers, water lines and conduit come through.
- Keep a 3-foot strip around buildings clear of brush, junk and weeds
- Mow close around barns and coops
- Store feed and seed in metal bins with tight lids
- Clean up spilled feed every day
- Seal gaps around feed augers, water lines and conduit
- Make sure doors close tight; add sweeps
- Raise hay bales off the ground on pallets
- Use hardware cloth on coop vents and openings
- Snap traps in covered boxes along walls

County-wide
Rodents at the barn, camp or lake house?
Call or send the form. We serve farms, camps and lake houses across Lafayette County. We seal what can be sealed, trap what is inside, and put the price in writing first.
Equipment
Equipment, vehicles and outbuildings
Anything that sits still long enough becomes a nest.
Tractors and trucks
Mice and rats nest in engine bays and chew wiring in vehicles that sit. Check before you start anything that has been parked for weeks.
Boats and campers
Stored boats and RVs make perfect nests. Remove food and bedding, close vents and hatches, and set traps inside.
Well and pump houses
Warm in winter and rarely opened. Chewed wiring here can leave you without water.
Woodpiles and brush
Stack wood off the ground and away from buildings. Brush piles near a barn are rat housing.
Deer stands and sheds
Small, closed spaces with seed and corn nearby. Store attractants in metal and check before each season.
Hay storage
Rats tunnel into stacked bales. Stack on pallets with a gap from walls so you can see and trap along the edges.

Straight answers
Rural property rodent questions
How much feed do rats eat?
An adult rat eats about 1 to 2 ounces of feed a day, according to Mississippi State University Extension. At 2 ounces a day that is about 46 pounds a year per rat, and they spoil much more than they eat with droppings and urine.
How do I keep mice out of my hunting camp?
Remove all food before you leave, store anything left in metal or hard plastic, seal gaps around pipes, vents and doors, add door sweeps, and set snap traps in covered boxes. When you return, air the camp out for 30 minutes before cleaning.
Is it safe to sweep out a camp full of mouse droppings?
No. The CDC says not to sweep or vacuum droppings, because it puts contaminated dust in the air. Air the building out first, wear gloves, and wet everything with disinfectant before wiping it up.
Are hantavirus cases a concern in Lafayette County?
The Mississippi State Department of Health says no hantavirus cases have been reported in the state since 1993. Deer mice, the main U.S. carrier, do live here, so the CDC cleanup steps still matter in camps and sheds.
Can you rodent-proof a barn?
Not completely. Mississippi State University Extension says a farm building cannot be made fully rodent-proof. Sealing the main gaps, storing feed in metal and keeping the perimeter clear cuts the problem down so trapping can handle the rest.
Do you serve rural properties outside Oxford?
Yes. We serve farms, camps and lake houses across Lafayette County, including Taylor, Abbeville, Paris and the Sardis Lake side. See our service area page.
What about rats around my chickens?
Rats eat feed and eggs and will kill chicks. Use a metal feed bin, collect eggs daily, close the coop at night, and cover vents and openings with hardware cloth.
