Protection During Outbreaks • Do not pick up or touch dead animals. • If plague has recently been found in your area, report any observations of sick or dead animals to the local health department or law enforcement officials. • If you anticipate being exposed to rodent fleas, apply insect repellents to clothing and skin, according to label instructions, to prevent flea bites. Wear gloves when handling potentially infected animals. • Eliminate sources of food and nesting places for rodents around homes, work places, and recreation areas. Remove brush, rock piles, junk, cluttered firewood, and potential food supplies (such as pet and wild animal food). Make your home rodent-proof. • If you live in an area where rodent plague occurs, treat pet dogs and cats for flea control regularly, and do not allow pets to roam freely. • Health authorities may use appropriate chemicals to kill fleas at selected sites during animal plague outbreaks.
