Homeowner Guides / Rodent cleanup
Do not sweep or vacuum dry rodent waste. For a small, accessible cleanup, the safest starting point is to wet the material thoroughly, wipe it up, disinfect the surface, and wash your hands. Heavy contamination needs a different level of protection.
This guide summarizes current CDC cleanup steps. It does not replace medical advice, product labels, or a professional assessment of a heavily contaminated space.
A few droppings on an accessible hard surface are different from a heavily contaminated attic, crawlspace, vacant building, or ventilation system. Keep children and pets away while you look over the area. Take a photo from a comfortable distance if it will help document where activity is occurring, but do not disturb the waste to get a better picture.
These steps are for a limited, accessible cleanup. Read the disinfectant label before starting, and follow any longer contact time or additional protective directions it gives.
Never mix bleach with ammonia or any other cleaner. Use cleaning products only as their labels direct. EPA explains that disinfectant contact time is the period the surface must remain visibly wet.

Wear gloves. Spray the rodent, nest, trap, and surrounding area with disinfectant until wet, then allow the required soak time. Place the material in a plastic bag, seal it, place that bag inside a second bag, and seal the outer bag. CDC says the double-bagged material can go into a covered garbage can that is regularly emptied; your state or local health department can advise on other disposal requirements.
If you plan to reuse a snap trap, follow CDC’s separate disinfection instructions rather than handling the rodent dry. Keep pets away from carcasses and nesting material.
Heavy infestations, vacant buildings with large numbers of rodents, contaminated insulation, and difficult attic or crawlspace work can require protective clothing, eye protection, respiratory protection, training, and fit testing. A basic dust mask is not a substitute for the respiratory protection CDC describes for heavy infestations.
If you become ill after a recent rodent exposure, talk to a healthcare provider and tell them about the exposure. For questions about a specific contamination risk, CDC also recommends contacting your local health department.
If new droppings appear after cleanup, note the room and location without sweeping them up dry. Supernova’s rodent approach combines indoor trapping, monitored exterior stations where appropriate, and entry-point work. We use traps—not rodenticide bait—inside homes, and we coordinate exclusion with the rodents already indoors.
Start with our mice and rodents service guide, then use the rodent entry-point checklist to understand how trapping, monitoring, and repairs fit together.
Tell us where the droppings or nesting material are, how much you are seeing, and whether the area is an attic, crawlspace, garage, living area, vehicle, or ventilation system. We can help you sort out the rodent-control next step and clarify what needs a specialized cleanup assessment.
