Roof Rat
Rattus rattus
An agile introduced rat that climbs trees and structures and often enters Florida attics, garages, sheds, and palm crowns.
Roof Rats thrive in Florida's warm climate and climb exceptionally well. They travel along fences, wires, vines, trees, and rooflines before entering small structural openings.
Food, water, dense cover, pet feed, fallen fruit, and easy access to buildings support infestations. Early exclusion prevents contamination and costly chewing damage.
Habitat:
Forests and Woodlands, Grasslands and Agricultural Areas, Urban and Residential Areas
Area / Range:
Statewide
Diet:
Omnivorous. Eats fruit, seeds, nuts, grains, pet food, garbage, insects, eggs, and many other available foods.
Behavior:
Mostly nocturnal, cautious, and social. Roof Rats follow established travel routes and often nest above ground in attics, dense vegetation, palms, or stored materials.
Nighttime, Dawn and Dusk
Active Times:
Best time to see:
After dark along fences, tree limbs, rooflines, attics, and dense vegetation.
Florida Native Status:
Introduced
Conservation Status:
Established nonnative pest species; not protected wildlife.
Safety Level:
Medium. Avoid Contact
Safety Information:
Avoid direct contact with rats, nests, droppings, and urine. Ventilate closed spaces, use gloves, disinfect contaminated areas, and seal entry points after activity is controlled.
Benefits to Property:
Provides prey for owls, hawks, snakes, and other predators, but offers little direct benefit around occupied properties.
Property Concerns:
Contaminates stored food, leaves droppings and urine, damages insulation, and chews wiring, irrigation tubing, wood, and plastic. It also carries parasites and pathogens.
Fun Fact:
- The tail is usually longer than the body.
- Roof Rats readily travel through tree canopies and overhead lines.
- An opening near one-half inch wide can allow entry.
Wildlife Laws:
Roof Rats are introduced pests and are not protected wildlife. Traps and rodenticides must be used according to product labels, local rules, and protections for children, pets, and nontarget wildlife.
Identification:
Slender body, pointed snout, large ears, large eyes, and a long thin tail usually longer than the head and body combined. Color ranges from black to gray-brown.
