When cleaning rodent droppings, urine, or nest materials, wear rubber gloves and a facemask with a HEPA filter. Ventilate the area. Don't stir up dust by sweeping or vacuuming. Instead, thoroughly wet contaminated material with a 10% chlorine bleach solution (1½ cups bleach in 1 gallon of water) or household disinfectant. Wipe up with a damp sponge and place in the garbage. Spray dead rodents and nests with disinfectant, then double-bag and dispose of them. Disinfect toys, silverware, or other items that may have been contaminated. Discard contaminated foods, drinks, napkins, paper plates, and cups.
