The safe way to clean up after mice or rats is to wet everything before you touch it. Air the room out, put on gloves, soak the droppings, urine and nests with a bleach solution or an EPA-registered disinfectant, wait 5 minutes, then wipe them up with paper towels. Never sweep or vacuum dry droppings: that's how germs end up in the air you breathe. This guide covers the CDC's step-by-step method, which disinfectants work (including Clorox wipes and Lysol), how to clean carpets, clothes, attics and cars, what to do if you already vacuumed, and what professional cleanup costs.
How do you clean up mouse or rat droppings? Open doors and windows for 30 minutes, put on rubber or plastic gloves, and spray the droppings until very wet with a fresh bleach solution (1.5 cups of bleach per gallon of water) or a product labeled "disinfectant." Let it soak 5 minutes, wipe it up with paper towels, throw them in a covered trash can, then disinfect the whole area.
What's the biggest mistake? Sweeping or vacuuming dry droppings. The CDC says rodent diseases spread mainly when people breathe in contaminated air.
What You Need
- Rubber, latex or vinyl gloves.
- A disinfectant: either a fresh bleach solution or a household product whose label says "disinfectant." See the products section below.
- A spray bottle, paper towels and trash bags.
- A mop or sponge for hard floors and surfaces.
- Insect repellent if you're handling dead rodents or nests. The CDC notes fleas are common on rodents.
- For heavy infestations: coveralls, rubber boots, goggles and a respirator with a HEPA filter (see below).
How to Mix the Bleach Solution
| Amount of water | Household bleach |
|---|---|
| 1 gallon | 1.5 cups |
| 1 quart (4 cups) | About 6 tablespoons |
| Ratio | 1 part bleach to 9 parts water |
That's the CDC's recipe. Mix it fresh each time you clean, and never mix bleach with ammonia or other cleaners. Stronger isn't better: some online advice suggests half bleach and half water, which is far more concentrated than needed and harder on your lungs and surfaces.
Step-by-Step: Cleaning Up Droppings and Urine
- Air it out. Open doors and windows for 30 minutes before you start, and leave the area while it airs. This is especially important in closed spaces like sheds, garages and cabins.
- Put on gloves.
- Soak, don't sweep. Spray droppings and urine with bleach solution or disinfectant until very wet. Let it sit 5 minutes, or as long as the product label says.
- Wipe it up with paper towels and put them in a covered garbage can that's emptied regularly.
- Disinfect the area. Mop or sponge floors, and wipe countertops, cabinets and drawers with disinfectant.
- Wash your gloved hands with soap and water or disinfectant before taking the gloves off.
- Wash your bare hands with soap and warm water.

Which Disinfectants Work? Clorox Wipes, Lysol and Bleach
Hantavirus, the most serious virus spread by rodent droppings, is one of the easiest kinds of virus to kill. When a hantavirus outbreak was reported in 2026, the EPA activated its emerging viral pathogen guidance and classed hantavirus as a "Tier 1" enveloped virus, the easiest category to inactivate. Its List Q of qualifying products includes many common household brands, for example:
| Product (EPA reg. no.) | How long the surface must stay wet | Use on |
|---|---|---|
| Clorox Disinfecting Wipes (5813-79) | 4 minutes | Hard, nonporous surfaces |
| Lysol Disinfectant Spray (777-99) | 10 minutes | Hard, nonporous surfaces |
| Lysol Disinfecting Wipes (777-114) | 10 minutes | Hard, nonporous surfaces |
| Bleach solution (CDC recipe) | 5 minutes | Hard surfaces |
The key is contact time. The EPA says the surface must stay visibly wet for the whole time listed on the label. That's why wipes aren't the right tool for a pile of droppings: a wipe can't soak the pile, and you'd end up smearing or crumbling it. Spray first to soak the droppings, wipe them up with paper towels, then use wipes for counters, cabinet shelves and handles. On Reddit (via Google search excerpts), one person worried that Clorox wipes "won't be strong enough." They are, as long as the surface stays wet for the full 4 minutes.
Dead Mice, Rats and Nests
- Put on gloves (and insect repellent for fleas).
- Spray the dead rodent, nest and surrounding area with disinfectant and let it soak 5 minutes.
- Put the rodent or nest in a plastic bag, with the trap if you're throwing it away. Tie it, then put it in a second bag and tie that too.
- Throw it in a covered garbage can.
- Wash gloved hands, remove gloves, wash hands again.
To reuse a snap trap, the CDC suggests dunking it with the rodent in a bucket of disinfectant for 5 minutes, dropping the rodent into a bag, then rinsing and drying the trap. If you can smell a dead rodent but can't find it, see how to get rid of dead rodent smell.
How to Clean Different Areas
- Kitchen and food areas: throw out any food in chewed or open packages. Disinfect cans and sealed jars before opening them, and clean shelves, drawers and counters. Wash dishes and utensils that may have been touched.
- Carpets, rugs and upholstery: after removing droppings, shampoo with a commercial disinfectant or use a commercial-grade steam cleaner, per the CDC.
- Clothing, bedding and stuffed animals: wash in hot water with detergent, then dry on high or in the sun.
- Books, papers and things you can't wash: the CDC suggests leaving them in sunlight for several hours, or storing them somewhere rodent-free for at least 3 weeks (6 weeks is better). Throw out cardboard boxes soiled with urine or droppings.
- Attics and insulation: bag insulation contaminated with urine and droppings and remove it. Heavily soiled attics often need the insulation replaced. If squirrels were the culprits, see squirrels in the attic.
- Garages, sheds and cabins: air out for 30 minutes first. Move boxes and stored items outside into the sun, stand upwind while you sort them, and spray dirt floors with disinfectant.
- Cars: open the doors, hood and trunk for 20 minutes. Disconnect the battery before working in the engine area. Don't vacuum or pressure-wash until everything is disinfected. If you find a nest in the air intake, replace the cabin air filter.
- Air ducts: if rodents got into the heating and cooling system, the CDC recommends a professional rodent service and a duct-cleaning company.
- Outdoors: wet droppings on patios, decks and porches with disinfectant before scraping them up, and wash hard surfaces down afterward.
I Already Vacuumed or Swept. What Now?
Don't panic. Finish the cleanup the right way from here on: soak what's left, then clean and disinfect the area. If your vacuum has a bag, spray it with disinfectant, seal it in a plastic bag and throw it out; for a bagless vacuum, empty the canister outdoors while wearing gloves and a mask, then disinfect it. The risk from one exposure is low for most homes in our area. The CDC says hantaviruses stay viable for about 2 to 3 days at room temperature, and sunlight kills them, so old, dried droppings carry less risk than fresh ones. If you develop fever, muscle aches, chills or trouble breathing within a few weeks, see a doctor and mention the rodent exposure.
How Worried Should You Be About Hantavirus?
Hantavirus is serious but rare, especially in the Carolinas and Virginia:
- 890 U.S. cases were reported from 1993 through 2023, according to the CDC, and 94% occurred west of the Mississippi River.
- The main U.S. carrier is the deer mouse. In the Southeast, related hantaviruses have been found in cotton rats and rice rats, and Norway rats can carry Seoul virus.
- It's dangerous when it happens: the CDC reports about 35% of U.S. cases were fatal.
- U.S. hantaviruses don't spread from person to person. The CDC says only the South American Andes virus does.
Hantavirus isn't the only reason to clean carefully. Rodent urine and droppings can also spread leptospirosis and salmonella. See are brown rats dangerous for the main rodent diseases.
Heavy Infestations: When to Call a Professional
For homes or buildings with heavy rodent activity, or that have been empty with lots of rodents, the CDC recommends more protection: disposable coveralls, rubber boots or shoe covers, gloves, goggles, and a half-mask respirator with a HEPA filter or a powered air-purifying respirator. Anyone hired to do the cleanup should follow OSHA rules on respirator fit testing. That's the point where most homeowners hire a pro.
Some pest control companies do cleanup and sanitizing as part of rodent work; others refer you to a remediation company. Ask before you hire. HomeGuide's cost guide gives these national averages, which aren't our prices:
| Service | Typical cost |
|---|---|
| Rodent infestation cleanup | $150 to $600 |
| Rodent-proofing (sealing entry points) | $100 to $800 |
| Attic decontamination | $700 to $11,000 |
| Attic restoration with new insulation | $3.30 to $5.50 per square foot |
| Insulation removal | $1 to $2 per square foot |
Keep Them From Coming Back
Cleanup only lasts if the rodents are gone and the gaps are sealed. Mice fit through gaps about 1/4 inch wide. See how mice get into your house and rodent proofing your home. Our rodent control service covers South Carolina, North Carolina and Virginia, including trapping and exclusion.

Frequently Asked Questions
A fresh bleach solution (1.5 cups of household bleach per gallon of water) or any product labeled as a disinfectant. The EPA's List Q of disinfectants that work against hantavirus includes common products like Clorox Disinfecting Wipes and Lysol Disinfectant Spray. Keep the surface wet for the contact time on the label.
Yes, for hard surfaces. Clorox Disinfecting Wipes are on the EPA's List Q for hantavirus with a 4-minute contact time, so the surface needs to stay visibly wet for 4 minutes. Don't use wipes on a pile of droppings; spray and soak those first, then wipe them up with paper towels.
Lysol Disinfectant Spray is on the EPA's List Q of products qualified against hantavirus, with a 10-minute contact time on hard, nonporous surfaces. Spray until the surface is wet and leave it for the full 10 minutes.
Not until they've been soaked with disinfectant and removed. The CDC warns that vacuuming or sweeping rodent droppings can put tiny virus-carrying droplets into the air. If you already vacuumed, finish the cleanup with the soak-and-wipe method and dispose of the vacuum contents carefully.
The CDC recommends 1.5 cups of household bleach per gallon of water, or 1 part bleach to 9 parts water. Mix it fresh each time and let it soak on droppings for 5 minutes.
The CDC says hantaviruses stay viable for about 2 to 3 days at room temperature, and sunlight kills them. Other germs in droppings can last longer, so treat all droppings as contaminated and clean them up with disinfectant.
Remove droppings first by soaking them with disinfectant and wiping them up. Then shampoo the carpet with a commercial disinfectant or use a commercial-grade steam cleaner, as the CDC recommends.
Some do as part of rodent control, and others refer you to a cleanup or remediation company. Ask before hiring. HomeGuide puts rodent infestation cleanup at $150 to $600 on average, and attic decontamination at $700 to $11,000.
For a few droppings, the CDC's guidance is gloves, airing out the room and soaking with disinfectant. For heavy infestations, it recommends a half-mask respirator with a HEPA filter, along with coveralls, goggles and boots.
