Mice and rats are known to carry many diseases. In Washington State, deer mice are the main carriers of hantavirus. Although this virus is rare, it is potentially fatal. Diseases from rodents can spread to humans through bite wounds, eating contaminated food, rodent ticks, mites, and fleas, and breathing in contaminated air from rodent urine or droppings.

THE BEST WAY TO PREVENT RODENT INFESTATIONS IS TO REMOVE THEIR SOURCES OF FOOD, WATER, AND SHELTER.

   HEALTH WARNING IF YOU HAVE RODENTS IN YOUR HOME OR YARD

While rare, deer mice are the main carriers of Hantavirus in Washington State

STAY SAFE WHEN CLEANING UP AFTER RODENTS


Wear disposable gloves and an N95 face mask or better.


DO NOT sweep, vacuum, or stir up dust that may have rodent droppings!
Wetting the area prior to cleaning can help prevent dust.
