Sacramento's greenery is its pride and a rodent's delight. Mature elms, oaks, palms and fruit trees overhang roofs throughout East Sacramento, Land Park, Curtis Park and Midtown, creating leafy highways for roof rats that travel from branch to eave to attic. Meanwhile, the American River Parkway, Sacramento River levees and creek corridors give Norway rats and mice cover and burrow sites. Wet winters push them to higher, drier spaces, often your house.

Roof rats, Norway rats and mice
Roof rats are agile climbers with long tails. They nest above ground in attics, tree crowns and dense vines, and they feed on oranges, persimmons, nuts and pet food. Norway rats burrow in the ground along foundations, under decks and near water, and they prefer lower levels of buildings. House mice squeeze through small cracks and nest in wall cavities, garages and boxes. Droppings are a clue: roof rat droppings are slim and pointed, while Norway rat droppings are fat and blunt.
Warning signs
- Footsteps, scratching or squeaks in the attic at dusk and during the night.
- Gnawed fruit or nut shells in yards, on fences and on rooftops.
- Grease marks and droppings along beams and the top of walls.
- Chewed insulation, wires or soffits.
- Burrows under sheds, decks and along fence lines.
Entry points in Sacramento houses
Older houses often have gaps where wood siding meets rooflines, loose attic vents, openings around plumbing stacks and chimney flashing, and worn crawl space vent screens. Newer homes can have gaps in garage doors, around dryer vents and along tile roof edges. Fences that touch the house, vines against walls and overhanging branches give rats a path. During flood season and heavy rain, creekside homes in Pocket and Natomas may see Norway rats seeking higher ground.
How removal works
- Inspection of the roofline, attic, crawl space, garage and yard to identify species and entry points.
- Trapping and, where appropriate, secured bait stations, with attention to children, pets and wildlife.
- Exclusion: closing gaps with metal flashing, hardware cloth and sealant, plus trimming trees.
- Cleaning and, if needed, replacement of contaminated insulation.
- Follow-up visits to confirm the work is complete.
Timing the work around the seasons
Fall is a smart time to inspect, because ripening fruit and the first rains push roof rats toward attics. Winter work focuses on sealing and trapping while animals are inside, and spring is a good time to trim trees and refresh weatherstripping. Mild weather means rodents remain active throughout the year, so a quick annual look at the roofline, vents and fence-to-house contact points keeps small gaps from turning into infestations.
Prevention
- Trim limbs at least a few feet from the roof.
- Harvest fruit and nuts promptly, and clean up windfalls.
- Thin ivy and heavy shrubs along walls and fences.
- Store pet food and bird seed in sealed containers.
- Use bins with tight lids, and keep compost closed.

Sacramento rodent FAQs
Why do rats come into the attic when it rains?
Wet weather drives them out of burrows and trees into dry shelters.
Is attic insulation ruined after rats?
It can be contaminated or flattened by nesting. A provider can advise on cleanup or replacement.
Can rats hurt my wiring?
Yes. They gnaw on cables, and damaged wiring is a fire hazard.
Will pruning trees solve the problem?
It helps, but you also need to seal the openings and remove the rats already inside.
