Reno sits at roughly 4,400 feet in the high desert, in the lee of the Sierra Nevada, with the Truckee River winding through downtown. Winters are cold and sometimes snowy, summers are hot and dry, and annual precipitation is low. That combination limits some pests while concentrating others around water, warm buildings and irrigated yards. A Reno homeowner's pest list looks different from a Las Vegas or Phoenix one.
What Reno actually has
Mice are the headline pest. Deer mice and house mice hit garages, sheds and attics from fall through spring, especially at the edges of the city where the sagebrush meets neighborhoods like Caughlin Ranch, Northwest Reno, Somersett and the foothills near Verdi. Along the river corridor and in older districts such as Midtown and the Old Southwest, Norway rats can be found. In spring and summer, ants arrive; carpenter ants appear where there are mature trees and damp wood, while odorous house ants and pavement ants come through kitchens. Wasps and yellowjackets nest in eaves and sheds, and spiders, including the occasional black widow, shelter in garages and woodpiles.
Scorpions, which are common in southern Nevada, are not typically a problem here, and termites are far less pressing than in warmer parts of the region.
How the high desert shapes the year
- Winter: freezing nights drive rodents toward heated structures and garages.
- Spring: snowmelt and rain bring ants, and the first wasp queens look for nesting sites.
- Summer: irrigation draws insects to lawns, and large daily temperature swings push spiders and crickets into homes.
- Fall: mice test every gap, and cluster flies and overwintering insects gather on sunny walls.
What licensed providers do
Technicians inspect the foundation, crawl space, garage and attic, looking for rodent entry points, moisture issues and insect nests. They may apply barrier treatments, bait for ants, traps for rodents, and remove or treat wasp nests. Because many Reno homes have crawl spaces with vents, or older foundations with gaps, sealing and screening is often part of the solution. Exterior treatments in the cold months are limited, so many providers focus on interior monitoring and exclusion in winter and treat the exterior from spring through early fall.
Home practices that help
- Seal openings around pipes and vents before the first freeze.
- Keep woodpiles away from the house and elevated off the ground.
- Reduce moisture near foundations by adjusting sprinklers.
- Store garage items in plastic bins, not cardboard.
- Trim vegetation back from siding and eaves.

Reno pest questions
Do I need pest control in a dry climate?
Many households do. Dry air limits some insects, but rodents, ants, spiders and wasps remain active, and irrigation attracts others.
Are there scorpions in Reno?
They are not a typical Reno issue the way they are farther south in Nevada and Arizona.
Why do I see so many mice in October?
Cool nights send field and deer mice toward warmth, and garages and sheds are easy targets.
Is hantavirus a concern?
Deer mice can carry it, so avoid sweeping droppings dry and use damp cleaning with gloves.
