What's in your attic? Roof rats vs. Norway rats vs. mice
Common signs are scratching or running sounds in the ceiling at night, droppings in the attic or garage, gnawed wires and greasy rub marks. Roof rats are sleek climbers with a tail longer than the body that nest above ground and favor attics. A licensed provider confirms the species before setting traps or sealing.
Hearing it overhead at night usually points to roof rats, but that is not a diagnosis. The table uses UC IPM's rat notes for roof rats and Norway rats, and the rat and mouse control page for the house-mouse size already published on this site.
| Roof rat | Norway rat | House mouse | |
|---|---|---|---|
| Build | Smaller and sleeker, with a tail longer than the head and body (UC IPM). | Stockier than a roof rat (UC IPM). | Small, about 2–3 inches, from this site's rodent page. |
| Where it lives | Nests above ground in trees, shrubs, and ivy. Indoors it favors attics, walls, and false ceilings (UC IPM). | Burrows along foundations and woodpiles. Indoors it favors ground floors (UC IPM). | Garages, kitchens, and wall voids. |
| Typical clue | Noise in the ceiling at night, droppings in the attic. | Burrows near foundations, activity at ground level. | Small droppings in cabinets. |
Why Torrance homes get roof rats
Roof rats thrive where landscaping is mature. UC IPM says residential areas with mature landscaping are good roof rat habitat, and that roof rats travel along utility lines, fences, and branches. They nest above ground and, indoors, favor attics. In Torrance they are a known issue where the city meets the Palos Verdes Peninsula canyons, which the Torrance termite page already notes, and the city page says occasional rodents drift in from those canyons. UC IPM's Pest Notes on rats describe roof rats as active year-round. Fall is a good time to seal entry points before winter rains. The homeowner walk-around for that sealing is in the fall rodent-proofing checklist. Torrance, in the Los Angeles South Bay, is the city this page is about.
Use the housing the site already describes, and do not read it as a rat count. Older wood and cedar in the Hollywood Riviera, postwar slab tracts in West Torrance, Walteria, and Southwood, and older wood in Old Torrance are the housing notes. None of those neighborhoods is labeled here as having more rats. There is no infestation statistic on this page.
The network covers Torrance ZIPs 90501 through 90505. The form starts at 90503. Change it if you are in another of those ZIPs. Old Torrance, the Hollywood Riviera, Southwood, Walteria, and West Torrance are the neighborhoods named on the city page.
How a licensed provider handles roof rats
Trapping removes the rats already inside, but exclusion keeps new ones out. UC IPM calls exclusion the most successful and longest-lasting strategy around structures: seal openings larger than 1/4 inch with steel wool, wire screen, or sheet metal, including roofline gaps. Pruning branches within 3 feet of the roof also helps. The provider does this work. South Bay Pest Pros does not inspect, trap, or seal.
The rodent page already says trapping without exclusion just invites the next rodent in. The steps below paraphrase that page and UC IPM. They describe what the licensed provider does.
- Inspection of the attic, roofline, eaves and vents, garage, utility penetrations, and vegetation touching the house.
- Trapping to remove the rats already inside. UC IPM calls snap traps the safest, most effective, and most economical trap, and says to place them off the ground for roof rats, on ledges, beams, and fences.
- Exclusion. UC IPM calls this the most successful and longest-lasting strategy around structures. Seal openings larger than 1/4 inch with steel wool, wire screen, or sheet metal. Rats chew plastic, foam, wood, and caulk.
- Cleanup and sanitizing of droppings and nesting material where needed, which the rodent FAQ on this site already describes.
- Prevention: prune limbs within 3 feet of the roof, thin dense plantings, and secure food and fallen fruit, from UC IPM Quick Tips.
Rodenticides, in one sentence
California restricts many rodenticides and the rules change; the licensed provider decides what is lawful and appropriate. This page does not name products or tell you to buy one.

What to do tonight and this week
Don't block the hole before the rats are out. A provider plans the order: trap, then seal. Note where and when you hear it, and photograph droppings without handling them barehanded.
The CDC's hantavirus prevention page says fresh urine, droppings, or nesting materials can put virus in the air when they are stirred up. Clean up safely using the CDC's steps, or leave that cleanup to the provider.
Bring pet food in at night and pick up fallen fruit. Then request a match. The provider, not South Bay Pest Pros, decides what the house needs.
