Rats & Mice

For self-defense, rats are nocturnal and become active after a premises has become quiet, or about one 1/2 hour after dusk. When left alone they will roam around day or night. Rats are color blind and have poor vision, but highly developed senses of smell, taste, hearing, and touch.

Rats are omnivorous but do have preferences. They prefer seeds, fresh vegetables or fruits. Norway rats prefer food high in fat content but will eat just about anything including clothing, leather, bone, lead, and plastic pipes, cement and wood.  They will even eat their own injured or weak.

Rats prefer nesting areas out of sight and reach of enemies and nests can be made up of any kinds of materials but they prefer bits of paper, rags, burlap, straw, and wood chips.
