Roof rats nest outside in trees, woodpiles and debris, and in dense vegetation. Inside, roof rats prefer to nest in the upper levels of a building in the attic and ceiling.
Roof rats are omnivorious, but tend to more vegetarian preferences. Typical food is fresh fruit, plant material, nuts and seeds, vegetables and even tree bark.

Rats can spread disease. Sometimes they transmit disease directly by contaminating food with their urine or feces or by biting people. Indirectly, they transmit by infecting as when fleas bite a disease-infected rat, then a person or other animal.
Rat burrows can cause structural damage by undermining the foundations of buildings, roads and walkways, can cause damage by gnawing, damaging plastic and lead pipes, door frames, upholstery, and electric wires, and can cause damage through the destruction and contamination of stored foods.
