Anyone who has pulled out a snow shovel in Reno knows that cold arrives fast at this elevation. Rodents know it too. As the nights turn frosty, mice and rats leave the sagebrush, riverbanks and vacant lots and head for places that are warm, dry and stocked with food. Reno's blend of high desert wildland, river corridor and older housing makes it a rodent-friendly town.
Meet the local rodents
Deer mice live in the sage, grass and rock outcrops on the city's edges and readily enter garages, sheds, cabins and crawl spaces. House mice live almost entirely around people and breed all year in heated buildings. Norway rats tunnel near the Truckee River, canals, older sewer lines and dense commercial areas like downtown and Midtown, entering buildings through foundation gaps and drains. Pack rats are a feature of the rocky hillsides near Caughlin Ranch and the Sierra foothills, where they stash sticks, cactus and trinkets in nests under decks and vehicle hoods. Ground squirrels and chipmunks add to the mix in spring.
Signs of trouble
- Droppings behind appliances and in drawers, cupboards and storage boxes.
- Chewed wires in a parked car, RV or boat, particularly after a period of disuse.
- Tiny tracks in dust, snow or soft soil near the foundation.
- Scratching and squeaking in walls or attic at night.
- Stored papers and insulation shredded to make nests.
Professional methods in a cold climate
A thorough job starts with identification, because each species needs a slightly different plan. Technicians look at crawl space vents, rim joists, garage doors, sill plates and the places where pipes and wiring enter. Reno homes with crawl spaces often have vents with torn screens or gaps under skirting. Technicians seal openings with metal flashing, mesh or concrete patch, then set traps along routes inside and, where appropriate, install tamper-resistant stations outside. In winter, ground work is limited, so exclusion and trapping from the inside continue while exterior sealing waits for thaw if needed.
Cleaning up is vital because deer mice can carry hantavirus in parts of Nevada. Droppings and nesting material should be wetted with disinfectant, wiped up with gloves and a mask, and never swept or vacuumed dry. Heavy contamination is a job for professionals.
How to harden a Reno home
- Replace missing foundation vent screens and mend gaps under crawl space doors.
- Keep firewood stacked away from the house and raised off the soil.
- Store pet food and birdseed in metal bins.
- Cut back vegetation and rock piles that give cover next to the foundation.
- Run engines or open hoods occasionally in stored vehicles to check for nests.

Rodent FAQ for Reno
Can mice chew through a garage door?
They can squeeze under worn seals and gnaw through soft materials. Replacing the bottom seal is a straightforward fix.
What attracts rats to the Truckee River corridor?
Water, vegetation and food waste from nearby properties create a good habitat.
Is poison safe around wildlife?
Poison can harm pets and predators such as owls and hawks, so providers often use snap traps and enclosed stations.
Do rodents leave in winter?
No. Cold weather pushes them closer to heated structures, so activity often increases.
