Habitat clues in a yard
Fences, wires and branches are roof rat highways, and citrus, avocado, figs, dates and bird seed are their food. Signs include half-eaten fruit, gnawed palm fronds and trails along fence tops. Norway rats, by contrast, dig burrows with smooth, packed entrances beside foundations, under sheds, next to dumpsters and along drains.
Where each shows up in the house
- Roof rats: attic insulation, rafters, ceiling noises, rub marks near roof vents
- Norway rats: garage floors, basement corners, crawl spaces, gaps at slab edges
- Both: kitchen cabinets, pantries and pet food areas
Control differs by species
- Roof rats: trap in attics and along beams, seal rooflines, trim trees and remove vine ladders
- Norway rats: seal ground-level gaps, fill burrows, fix drainage, secure trash and place traps along runs
- Both: store food properly, remove pet food at night and clean droppings safely
Cleanup after either rat
Start by wetting the droppings with disinfectant, then wipe them up with disposable towels while wearing gloves and a suitable respirator, and bag everything. Dry material should never be swept or vacuumed. Sticking to CDC and EPA cleanup guidance counts for more than the brand of product.
Prevent both species
- Keep firewood and debris off the ground away from the house
- Seal gaps at vents, soffits, pipes and the foundation
- Pick up fallen fruit and keep compost closed
- Trim branches to keep a few feet of space from the roof
Myths and facts about rodents
- Myth: cats solve a rodent problem. Fact: they may catch some, but they do not seal entry points.
- Myth: a rat needs a big hole. Fact: a rat fits through about half an inch and a mouse through about a quarter inch.
- Myth: you only have rodents if you see them. Fact: they are nocturnal and the first clue is often droppings or noises.
- Myth: ultrasonic devices drive rodents out. Fact: independent evidence is weak and rodents get used to the sound.
- Myth: poison alone fixes it. Fact: poison does not close gaps and can leave dead animals inside walls.

| Norway rat | 7 to 9 inches, tail shorter than body | 3/4 inch, capsule shaped | Burrows at foundations, basements, drains |
| Pack rat (woodrat) | Larger, furry tail, large ears | Larger, dark, often in piles | Stick middens in garages, sheds, engine bays |

What rodents damage besides food
Constant gnawing comes naturally to rats and mice, since a rodent's teeth never stop growing. The damage includes chewed electrical wiring (a fire hazard), stripped insulation in attics and walls, gnawed plumbing and irrigation lines, harmed stored boxes and vehicles, and surfaces fouled with droppings and urine.
Check attic wiring, ductwork and insulation after rodents have been in the house, and call a licensed electrician or HVAC professional about anything chewed.
When to call a professional
Pick up the phone when the pest is a mystery, when your own efforts have not stopped it from returning, when it is hiding in walls, attics or crawl spaces, or when children, pets or health conditions rule out guesswork.

Common questions about roof rats vs norway rats
Which rat is more common in houses?
It varies with the region and the building: roof rats are common where landscapes are warm and full of fruit trees and palms, and Norway rats are common in older structures at ground level that have drainage problems.
How can I tell the difference by tail length?
A roof rat's tail is longer than its body, while a Norway rat's tail is shorter than its body.
Do roof rats live in trees?
Roofs and attics are reached from nests in dense trees, vines and palms, where roof rats often live.
Can both be in the same house?
They can, but typically in different parts, roof rats above and Norway rats below.
Are roof rats more dangerous?
Both carry risks. Roof rats are more likely to chew electrical wiring in attics, which can be a fire hazard.
How do I tell if a burrow is a rat's?
Look beside foundations and slabs for burrow entrances two to three inches wide that look clean and smooth; those belong to Norway rats.
