When cleaning up after a rodent infestation, the most important thing is NOT to create dust. DO NOT sweep or vacuum up rodent droppings.

Follow these steps:

  • Put on rubber, latex, or vinyl gloves.
  • Wet the droppings, urine, and nesting materials with a spray disinfectant. The CDC recommends one part bleach to nine parts water.
  • Let the disinfectant soak in for five minutes.
  • Use a paper towel to pick up the droppings and other waste. Put it in the garbage.
  • After removing the droppings and nesting materials, spray down any items rodents might have contaminated.
  • Mop the floors and clean countertops with disinfectant.
  • Steam-clean or shampoo upholstered furniture and carpets where rodents have been.
  • Wash any bedding or clothing that might have been exposed to rodents or their droppings/urine with laundry detergent in hot water.
  • Remove the gloves and wash your hands thoroughly.
