Disinfect the droppings by spraying them with a solution of bleach and water (1 part bleach to 10 parts water) and allowing the solution to sit for 5 minutes. Vinegar is not an effective alternative.

If using a store-bought disinfectant, follow the instructions on the label. Use disposable rags or paper towels to pick up the droppings and place them in a sealed trash bag for disposal.

Insulation is one of the reasons why rodents choose to build their nests in attics. Although the insulation material may not be a food source for the mice, they still chew on it to keep their teeth trimmed.

During the cleaning process, inspect any exposed insulation for urine and droppings. If present, handle the contaminated material carefully and place it in plastic bags for disposal.

If you have non-washable items, take advantage of the ultraviolet rays from the sun to inactivate hantaviruses. Just leave the items in the sun for several hours. After drying them, wipe them with a cloth dampened with disinfectant.

5. Disinfect your attic
