Rodent repellents of various types can be purchased from established online retailers, as well as from leading brick-and-mortar retail chains in the United States. Rodents such as mice and rats can enter and infest a home or any other enclosed structure to seek shelter and food, especially during the cold season.
Mice and rats can cause and spread more than 35 different diseases, as reported by the Centers for Disease Control and Prevention. In the U.S., rodents are known to carry diseases such as the hantavirus pulmonary syndrome, leptospirosis and rat-bite fever. Rats and mice are also known to carry the lymphocytic choriomeningitis virus, which can be dangerous particularly to pregnant women.
Mice and rats can enter a home via any small hole or gaps. These rodents can pass through holes that are smaller than what most people think is possible. Rats can enter a hole or a gap that is as big as half-a-quarter, and mice can pass through a hole that is the size of nickel.
Once a rat or mouse infestation is suspected, the CDC recommends safely cleaning the area infested by the rodents, trapping rodents that are already in the house and sealing holes and gaps that the rodents may use to gain entry. Residents can also try setting up and using commercially available rodent repellents that may dissuade the pests from entering the house. Such repellents come in the form of sprays, pellets and high-pitched noise makers.
