Never sweep or vacuum. For heavy infestations or attics or crawl spaces full of droppings, arrange professional cleanup.
Open doors and windows for 30 minutes before cleaning. Leave the area meanwhile.
Wear rubber or plastic gloves. Spray droppings until very wet with an EPA-registered disinfectant.
Wait 5 minutes or follow the disinfectant label. Wipe up with paper towels.
Put used towels in a covered garbage can emptied regularly. Mop or wipe surfaces with disinfectant.
Wash gloved hands. Remove gloves, then wash hands with soap and warm water.
If you feel unwell, contact a doctor promptly and tell them about the exposure.
