Animal Waste and Urine Cleanup in Homes

By Muhammad Ishaq Hassan. Updated October 3, 2026. 3 min read.

Short answer: Small pet accidents can be cleaned with enzyme cleaners. Urine that soaked into carpet pad and subfloor, droppings from rodents, bats or raccoons, and homes with many animals need careful or professional cleanup, because waste can carry germs and parasites and odor soaks deep into materials.

Animal waste ranges from a single pet accident to attics full of droppings and homes where many animals lived. This guide explains animal waste cleanup, the health risks, and when to call a biohazard cleanup company.

Pet urine and accidents

Blot up fresh urine with paper towels, pressing hard.
Apply an enzyme cleaner made for pet urine and let it work as the label says.
Avoid steam cleaning fresh urine stains, since heat can set the odor.
Use a black light to find old stains you cannot see.

When urine has soaked through carpet into the pad and subfloor, surface cleaning will not remove the smell. The pad may need replacing, and the subfloor cleaned and sealed with an odor blocking primer.

Wildlife droppings

Rodents: droppings can carry hantavirus and other germs. Follow CDC wet cleaning steps.
Bats: bat droppings, called guano, can grow a fungus that causes histoplasmosis when disturbed. Large amounts need professional removal.
Raccoons: raccoon droppings can carry roundworm eggs that are harmful to people. Do not clean latrines without protection.
Birds: large amounts of droppings in attics or vents can also carry fungi.

Do not sweep or dry vacuum animal droppings, which puts particles into the air. Wear gloves and an N95 mask, wet the droppings first, or call a professional.
