Put on goggles, a face mask and work gloves to protect yourself from mold spores or rodent droppings.
Open any skirting or lattice work along the bottom of your mobile home. Direct the light from a flashlight under the mobile home for better visibility.
Remove any dead animal carcasses, leaves, garbage or debris with a rake. Once the items are removed from under your mobile home, seal them up in a trash bag.
Fill a large spray bottle with 1/2-cup of bleach and 5 cups of water. Spray the area where a dead animal was removed or rodent droppings were seen.
Leave the bleach spray on the surface for 20 minutes to sanitize the area. Use the rake to remove any further debris.
Allow the area underneath your mobile home to air-dry for three to seven hours with the skirting open.
Sprinkle a layer of activated charcoal underneath your mobile home to absorb any remaining odors. Close the skirting or lattice work.
