What Kind of Rat Do You Have? The 2 Species That Invade US Homes

Nearly every home rat problem in the US comes down to two species — and they behave very differently. Norway rats live low (burrows, basements, foundations), roof rats live high (attics, rooflines, trees). Knowing which one you have tells you where to put every trap.

SpeciesKey lookWhere it livesTypical signs
Norway Rat
(Brown / Sewer Rat)
Heavy, thick body up to 10″ plus a shorter, scaly tail; blunt nose, small ears, brownish-gray furGround level and below: burrows near foundations, under decks and sheds, basements, crawlspaces, garagesDirt burrows with 2–3″ openings, capsule droppings ¾″ with blunt ends, gnawed door corners and bins
Roof Rat
(Black Rat)
Slimmer body up to 8″ with a tail longer than the body; pointed nose, large ears, dark furUp high: attics, ceilings, rooflines, soffits, trees and vines touching the house, garage raftersNighttime noise overhead, greasy rub marks along beams, spindle-shaped droppings ½″ with pointed ends
Not sure it’s a rat?Mice are far smaller (2–4″ body), with proportionally bigger ears and rice-sized droppingsKitchens, cabinets, wall voids — anywhere with dime-sized gapsLight fast scratching, tiny scattered pellets — if that’s your case, use the mice guides instead

Quick Test: Rat or Mouse?

Rats and mice need different traps, different bait, and different sealing gaps. Answer three questions about what you’ve found — it’s the fastest way to avoid buying the wrong products.

Rat Control FAQ

What is the best first product to buy for rats?
A multi-pack of rat-sized snap traps. Place several along walls and runways at the same time — coverage matters more than any single trap’s design. Never start with mouse traps, repellent pouches, or ultrasonic devices for an active rat problem.
Can mouse traps catch rats?
Not reliably. Adult rats are far larger and stronger, so undersized traps miss, injure, or get avoided — and a rat that escapes a trap becomes trap-shy and much harder to remove afterward.
Where should I put rat traps?
Along walls with the baited trigger side facing the wall, behind stored items, near droppings and greasy rub marks, beside garage edges, and along attic beams. Rats hug edges when they travel — put the trap in the edge, not in open floor space.
Is poison better than traps for rats?
Traps are the safer first choice indoors: you control the removal, and there’s no risk of a poisoned rat dying inside a wall or attic. Poison belongs only in secured, tamper-resistant outdoor bait stations for heavy exterior pressure — ideally as part of a professional program.
How long does it take to get rid of rats?
A small, recent problem often improves within days once traps and food cleanup are working together. Established or hidden infestations take multiple weeks, because trapping, sanitation, and exclusion all have to run in parallel.
When should I call a professional?
If you see rats during the day, find droppings in several rooms or levels, notice strong urine odor or contaminated insulation, discover chewed wiring, or trap activity continues for more than two weeks without dropping. Those signs point to an established colony or a safety hazard, not a DIY-sized problem.
