Cleaning Up After Rodents

Urine and Droppings

Take precautions before and during cleanup of rodent-infested areas. Before cleaning, trap the rodents and seal up any entryways to ensure that no rodents can get in. Continue trapping for a week. If no rodents are captured, the active infestation has been eliminated and enough time has passed so that any infectious virus in the rodent’s urine/droppings or nesting material is no longer infectious.

Before starting cleanup of the space, ventilate the space by opening the doors and windows for at least 30 minutes to allow fresh air to enter the area. Use cross-ventilation and leave the area during the airing-out period.

First, clean up any urine and droppings

When you begin cleaning, it is important that you do not stir up dust by sweeping or vacuuming up droppings, urine, or nesting materials.

  • Wear rubber, latex, or vinyl gloves when cleaning urine and droppings.
  • Spray the urine and droppings with a disinfectant or a mixture of bleach and water and let soak 5 minutes. The recommended concentration of bleach solution is 1 part bleach to 10 parts water. When using a commercial disinfectant, following the manufacturer’s instructions on the label for dilution and disinfection time.
  • Use a paper towel to pick up the urine and droppings, and dispose of the waste in the garbage.
  • After the rodent droppings and urine have been removed, disinfect items that might have been contaminated by rodents or their urine and droppings.

Next, clean and disinfect the whole area

  • Mop floors and clean countertops with disinfectant or bleach solution.
  • Steam clean or shampoo upholstered furniture and carpets with evidence of rodent exposure.
  • Wash any bedding and clothing with laundry detergent in hot water if exposed to rodent urine or droppings.

Lastly, remove gloves, and thoroughly wash hands with soap and water (or use a waterless alcohol-based hand rub when soap is not available and hands are not visibly soiled).
