If you attempt cleaning up rat droppings, definite precautions must be taken. Wear gloves, a mask, and goggles to prevent direct contact and inhalation of airborne particles. Open windows for ventilation. Using a disinfectant or a mixture of bleach and water (1 part bleach to 9 parts water), thoroughly wet down the contaminated areas. You want to avoid disturbing dry surface particles. Allow the solution to sit for  at least 5 minutes.  Gently wipe up the feces with paper towels, taking care not to create dust. Dispose of the paper towels in a sealed plastic bag.  Scrub the area with a brush or scrubbing pad, applying the disinfectant solution once again. Rinse thoroughly with clean water and wipe dry.

Dispose of all cleaning materials, gloves, and protective gear in sealed bags. Wash your hands thoroughly with soap and hot water for at least 20 seconds.  Don’t forget to disinfect any cleaning tools used during the process.
