After loose materials like mouse nests have been gathered up, wipe down cabinet shelves, countertops and other areas with disinfectant. Mop the floors in affected areas, too. Use a disposable mop head and paper towels or sponges you can discard afterward. Be generous with disinfectant. Remember, wet (saturated) is good. Shampoo or steam clean affected carpets, upholstery and area rugs.
