How do you safely clean up mouse or rat droppings?
Open doors and windows and leave the area for 30 minutes. Put on rubber or plastic gloves. Spray the droppings and urine with a disinfectant, or a fresh mix of 1.5 cups of household bleach per gallon of water, until soaked, and let it sit for 5 minutes. Wipe up with paper towels, throw them away in a covered trash can, then disinfect the surface and wash your gloved hands before taking the gloves off. Never sweep or vacuum droppings, because that puts contaminated dust in the air. This is the CDC method. In Mississippi, no hantavirus cases have been reported since 1993, but rodent droppings and urine can still spread salmonella, leptospirosis and other illnesses.
Identify them
Mouse, rat or something else? How to identify droppings
Size and shape tell you the species, and the species tells you where the gap is. Mouse figures from University of Nebraska Extension; rat sizes follow Mississippi State University Extension.
| Animal | Size | Shape | Where you usually find them |
|---|---|---|---|
| House mouse | 1/8 to 1/4 inch | Small, with one or both ends pointed | Kitchen drawers, under sinks, behind the stove, pantry shelves |
| Roof rat | About 1/2 inch | Long, with pointed ends | Attic, along rafters, top shelves, garage rafters |
| Norway rat | About 3/4 inch | Capsule shaped, blunt ends | Crawl space, foundation, garage floor, near trash |
| Squirrel | Larger and rounder than a rat’s | Barrel shaped, often lighter in color | Near attic entry points at the roofline |
| Bat | Similar to a mouse’s | Crumbles to powder when pressed, shiny specks | Piled under one roosting spot, often in the attic |
| Cockroach | Under 1/8 inch | Like ground pepper or coffee grounds | Cabinet corners, behind the fridge |
Fresh or old? Fresh droppings are dark, moist and soft. Old ones are dry, gray and crumble. Clean up everything once, then check the same spots in a few days. New droppings mean rodents are still active. For more on telling the species apart, see our rat and mouse pages.
Health risks
Health risks from rodent droppings and urine
Most of these are uncommon. All of them are easy to avoid with the right cleanup. This is general information, not medical advice.
| Illness | How people get it | Main rodents | The Mississippi picture |
|---|---|---|---|
| Hantavirus pulmonary syndrome | Breathing dust from dried urine, droppings or nests | Deer mouse mostly; cotton rats and rice rats in the Southeast | No cases reported in Mississippi since it became reportable in 1993, per MSDH |
| Leptospirosis | Urine in water or soil, through cuts, eyes or mouth | Rats | Risk rises after flooding and in standing water |
| Salmonellosis | Food or surfaces contaminated by droppings | Mice and rats | The most likely problem in a kitchen with mice |
| Rat-bite fever | Bites, scratches, or food and water contaminated by rats | Rats | Rare. Never handle live rats |
| LCMV | Fresh urine, droppings, saliva or nesting of house mice | House mouse | A special concern during pregnancy |
| Asthma and allergies | Breathing mouse urine and dander allergens | House mouse | Long infestations in older homes are the usual cause |
Should you worry about hantavirus in Oxford? The risk is low, but not zero. The CDC counts 890 confirmed U.S. cases from 1993 through 2023, and 94% were west of the Mississippi River. After the spring 2026 Andes virus cluster tied to a cruise ship, state health officials said Mississippi had no confirmed cases.
That is not a reason to sweep up droppings in a closed shed. The CDC cleanup steps exist because the virus spreads through dust, and the same steps protect you from the illnesses that are more common here.
- Fever, aches and fatigue 1 to 8 weeks after cleaning a rodent area
- Shortness of breath or coughing that follows
- Tell your doctor you were around rodents
- Pregnant? Let someone else handle the cleanup
- Kids and pets stay out until the area is done
The CDC method
How to clean up rodent droppings safely, step by step
Follows the CDC’s cleanup guidance for homes, outbuildings, cabins, sheds and barns.
Air it out
Open doors and windows and leave for 30 minutes. In a shed, cabin or camp, do this every time it has been closed up.
Gloves on
Rubber or plastic gloves. In a dusty attic or barn, add a mask and old clothes you can wash right after.
Soak it
Spray droppings and urine with disinfectant or 1.5 cups of bleach per gallon of water. Let it sit 5 minutes.
Wipe and bag
Pick up with paper towels. Bag dead rodents and nests twice, knotted, into a covered trash can.
Disinfect
Mop floors and wipe counters, cabinets and drawers. Throw out soiled cardboard and any food the rodents reached.
Wash up
Wash gloved hands, take off the gloves, then wash bare hands with soap and warm water.
Mix bleach fresh each time and never mix it with ammonia or other cleaners.
Do and don’t
What to do, and what never to do, with droppings
Most mistakes come from treating droppings like ordinary dust.
Do
- Air the space out for 30 minutes first.
- Wet everything down before touching it.
- Use paper towels you can throw away.
- Throw out food and cardboard the rodents reached.
- Take a photo before cleaning if you plan to call a pro.
Never
- Sweep, vacuum or use a leaf blower on droppings.
- Pick up droppings or dead rodents bare handed.
- Mix bleach with ammonia or other cleaners.
- Clean a duct system yourself. The CDC says call a professional.
- Clean up and skip finding the gap. They will be back.
Already vacuumed? Do not panic. The CDC says to follow the cleanup steps anyway. Empty the canister outside, wearing gloves, into a sealed bag, and wipe the vacuum down with disinfectant.
Special cases
Attics, crawl spaces, cars, and hunting camps
The CDC method works everywhere. These spots each need one extra step.
Attic insulation
The CDC says to bag insulation soiled with urine or droppings for removal. A few droppings near one entry point rarely means replacing the whole attic. Ask for photos before paying for that, and see our attic cleanup guide.
Crawl spaces
Norway rats nest here. The space is tight and dusty, so wet cleaning matters more, not less. Check that vent screens and the access door are sealed afterward.
HVAC ducts
Droppings in ducts or a smell from the vents means the system needs a professional. The CDC advises calling a rodent professional and a duct cleaning company, not running the fan to clear it.
Cars and trucks
Check the engine bay and the cabin air filter. A nest in the filter housing blows dust into the cab every time the fan runs. Replace the filter after cleanup.
Camps, cabins and sheds
Places closed up all summer around Sardis Lake and rural Lafayette County are where native deer mice and cotton rats move in. Air out for 30 minutes, every time.
Stored boxes
Move boxes outside into sunlight and a breeze. Throw out soiled cardboard. Wipe plastic, glass and metal containers with disinfectant.
Stop the droppings at the source
Cleaned up and still finding new ones?
New droppings mean an open gap. Call or send the form. We find every entry point, seal it with metal, and trap the rodents still inside.
When to call us
When to call a professional instead of cleaning it yourself
Some jobs are a spray bottle and ten minutes. Some are not.
A few droppings in a kitchen drawer is a job for you, a pair of gloves and a spray bottle. A lot of droppings spread across an attic or crawl space is a different job.
Either way, cleaning up does not fix anything by itself. The droppings tell you rodents have a way in. Until that gap is sealed, you will keep cleaning.
- Droppings across a large area of attic or crawl space
- Droppings or a smell coming from the air ducts
- A dead rodent smell you cannot locate
- New droppings within a few days of cleaning
- Anyone in the home is pregnant or has asthma
- Droppings near a crib, pet food or food storage
Hiring us? Take a photo before you clean. The location and size of droppings help us find the entry point. Here is how our process works.

Straight answers
Questions about rodent droppings
Can you get sick from touching mouse droppings?
You can, mainly through salmonella if you touch your mouth or food afterward. That is why the CDC says to wear gloves, wet droppings down first, and wash your hands after. Breathing dust from dried droppings is the bigger risk, which is why you never sweep or vacuum them.
Is hantavirus a risk in Oxford, Mississippi?
The risk is low. The Mississippi State Department of Health says no hantavirus cases have been reported in the state since it became nationally reportable in 1993. Native rodents that can carry hantaviruses do live in the Southeast, so the CDC cleanup steps still apply, especially in closed sheds, camps and barns.
How do I tell mouse droppings from rat droppings?
Size. Mouse droppings are 1/8 to 1/4 inch, about the size of a grain of rice. Roof rat droppings are about 1/2 inch with pointed ends; Norway rat droppings are about 3/4 inch with blunt ends.
Can I use regular bleach?
Yes. Use plain household bleach at 1.5 cups per gallon of water, mixed fresh, or a product labeled as a disinfectant. Let it sit 5 minutes, or as long as the label says, before wiping.
Should I wear a mask?
The CDC’s home guidance centers on airing out, gloves and wet cleaning, which keep dust down. In a dusty attic, barn or crawl space, a well-fitting mask is a sensible extra step.
How do I know if the droppings are new?
Fresh droppings are dark, shiny and soft. Old ones are dull, gray and dry. Clean up all of them, then check the same spots in two or three days. Anything new means rodents are still active.
Do I need to replace my attic insulation?
Only when it is heavily soiled with urine and droppings. The CDC says to bag contaminated insulation for removal, but a small area near one entry point can often be removed in sections. Ask for photos of the contamination before agreeing to full replacement.
