Most are small mammals that feed primarily on plants, though some rodents will eat practically anything. In places where humans live, rodents are often considered pests because they contaminate food, damage houses, and spread diseases.
Many types of snap traps, glue traps, and live capture traps are commercially available. However, incorrectly placing baits or traps can make rodent infestations worse and lead to further damage. Homeowners should allow pest control experts handle rodent infestations in the most effective and humane way possible.
