A dead mouse indoors needs calm, careful cleanup. Avoid direct contact, wet the area with disinfectant, double bag the mouse, and clean nearby droppings without sweeping or vacuuming them.
Prepare Before You Touch Anything
Keep children and pets away. If you can safely access the doors and windows, open them and leave the area for 30 minutes before cleaning.
If you cannot ventilate safely, ask your local health department or a pest professional for help. Otherwise, return after airing out and put on rubber or plastic gloves.
Use a general household product whose label says it is a disinfectant. Follow its contact-time directions.
CDC also gives a fresh bleach alternative of 1.5 cups household bleach in one gallon of water, or one part bleach to nine parts water.
Never mix bleach with ammonia or another cleaner. Use a labeled disinfectant instead if you are unsure about safe mixing or ventilation.
- Safely open doors and windows, then leave for 30 minutes before cleaning.
- Return and wear rubber or plastic gloves.
- Wet the mouse, trap, nest, and surrounding area with disinfectant.
- Wait five minutes, or use the label’s contact time.
- Place the mouse, nesting material, and disposable trap in a plastic bag.
- Knot the bag, place it in a second bag, and knot that bag.
- Put it in a covered garbage can that is emptied regularly.
- Wash gloved hands, remove the gloves, then wash bare hands with soap and warm water.
Clean the Mouse and Nearby Area
Spray the dead mouse, trap, nest, and surrounding area until wet. Let the disinfectant sit for five minutes or for the time printed on its label.
Do not sweep or vacuum dry urine, droppings, or nesting material. That can stir contaminated particles into the air.
Use paper towels to pick up wet material. Put the towels in the disposal bag, then disinfect hard surfaces around the area.
Bag and Discard the Mouse
Place the mouse and any disposable trap or nesting material in a plastic bag. Tie the bag closed, place it inside a second bag, and tie that bag.
CDC says the double-bagged waste can go in a covered garbage can that is emptied regularly. Your state health department can advise on another local route.
Wash your gloved hands with soap and water or disinfectant before removing the gloves. Then wash your bare hands with soap and warm water.
Handle a Reusable Snap Trap Carefully
CDC says a reusable snap trap can be submerged with the rodent in disinfectant for five minutes while you wear rubber gloves.
Hold the trap over the open bag, lift the bar, and let the mouse drop into the bag. Rinse the trap and let it dry completely.
Do not improvise this method for electronic traps or another trap type. Follow the manufacturer’s cleaning instructions.
Know When to Get Help
Heavy infestations need additional precautions. If you see piles of droppings, many nests, or several dead rodents, contact a pest professional or local health department before cleaning.
Talk to a healthcare provider if you become ill after rodent exposure. Tell them about the exposure so they can assess it properly.
Once the area is clean, seal holes and remove food sources to prevent another infestation.
