Squirrel Control in Nevada: A Homeowner’s Complete Guide
You hear scrabbling in the attic at dawn. A pine cone appears on your porch. Your bird feeder is mysteriously emptied overnight. These are classic signs that squirrels have moved in—and they’re not paying rent. In Nevada, from the Sierra Nevada foothills to the Mojave Desert, squirrels (primarily Eastern gray and rock squirrels) are adept at turning attics, crawl spaces, and walls into their personal nurseries and pantries. Ignoring the problem risks costly structural damage, electrical fires, and health hazards from droppings and urine.

The Problem
squirrels are not just cute; they are relentless chewers. Their incisors grow continuously—up to six inches per year—so they must gnaw constantly to keep them filed down. In your home, that means wood, drywall, electrical wiring, and even gas lines become targets. According to the National Pest Management Association, squirrels are responsible for thousands of house fires annually due to gnawed wiring. In Nevada, where many homes have older wiring or wooden eaves, the risk is especially high. Additionally, squirrel urine and feces can carry leptospirosis and salmonella, and their nesting materials attract secondary pests like mites and fleas.
Warning Signs
- •Scratching, scurrying, or thumping sounds in the attic, especially at dawn and dusk.
- •Droppings that are oblong, about 3/8 inch long, often found in attics or near entry points.
- •Gnaw marks on wood, soffits, fascia boards, or electrical wires (look for chewed insulation).
- •Visible entry holes: gaps around vents, eaves, or rooflines that are roughly 1.5 to 2 inches wide.
- •Nests made of leaves, twigs, and insulation in attic corners or wall voids.
- •Tracks or tail drag marks in dusty attic spaces.
- •Strange odors from urine accumulation or decomposing carcasses.
Risks of Waiting
- ⚠Electrical fires from gnawed wiring—a leading cause of squirrel-related property damage.
- ⚠Structural damage to wood, drywall, and insulation as squirrels expand their nests.
- ⚠Health risks from leptospirosis, salmonella, and parasites carried by squirrels.
- ⚠Secondary infestations: fleas, mites, and flies breeding in nests or dead animals.
- ⚠Increased exclusion costs: a small hole becomes a large gap over time.

Treatment Options
One-Way Exclusion Doors
$250–$500A wire or plastic door is installed over the main entry point, allowing squirrels to exit but not re-enter. This humane method is the industry standard. After a few days, the door is removed and the hole is sealed.
Live Trapping and Relocation
$300–$600Cage traps baited with nuts or seeds are placed in attics or on roofs. Trapped squirrels are relocated to suitable habitat. Requires daily checks and compliance with Nevada wildlife laws.
Exclusion and Repair
$500–$1,500After removal, all potential entry points are sealed with heavy-gauge steel mesh, caulk, or flashing. Damaged wood, vents, and eaves are repaired to prevent re-entry.
Squirrel Behavior and Biology
Eastern gray squirrels (Sciurus carolinensis) and rock squirrels (Otospermophilus variegatus) are the primary nuisance species in Nevada. Gray squirrels are tree-dwellers found in urban and suburban areas with mature trees, especially in northern Nevada around Reno and Carson City. Rock squirrels are ground-dwellers common in southern Nevada, including Las Vegas; they often burrow under foundations and patios. squirrels have two breeding seasons: January–February and June–July, with gestation about 44 days. Young are independent at 10–12 weeks. In late summer and fall, juveniles disperse and seek new territory—often your attic. They cache food (acorns, pine nuts) for winter, but attics offer warmth and shelter, making them irresistible. Their keen sense of smell leads them to food crumbs, pet food, and birdseed. Understanding these patterns helps target exclusion timing: best done in late winter after the first litter and again in late summer before the second litter disperses.
The Exclusion Process: Step by Step
Professional squirrel exclusion follows a strict protocol. First, a thorough inspection identifies all entry points, often hidden behind soffits, vents, or loose shingles. Technicians use ladders, flashlights, and sometimes thermal imaging to find gaps. Next, one-way exclusion doors are installed over the primary opening. These doors are angled so squirrels can push out but cannot push back in. All other openings are temporarily sealed to force squirrels to use the one-way door. After 3–7 days, when no further activity is detected, the door is removed and the hole is permanently sealed with galvanized steel mesh, copper mesh, or sheet metal. Damaged wood or wiring is repaired. Finally, attic insulation may be replaced if contaminated with urine or droppings. This process is humane, effective, and backed by a service guarantee. Do not attempt to seal a squirrel inside; a dead animal will decompose and attract flies and odors.
Nevada-Specific Challenges
Nevada’s diverse climate affects squirrel behavior. In the northern mountainous regions, winters are cold and snowy, driving squirrels into attics for warmth. In southern deserts, summers are scorching, but squirrels seek cooler attics and shade. Rock squirrels in Las Vegas burrow under concrete slabs and patios, causing foundation damage. Urban sprawl in Reno and Las Vegas has created abundant food sources (ornamental trees, bird feeders, trash) that sustain high squirrel populations. Additionally, Nevada’s wildlife laws require that squirrels be released on the same property (if trapped) or euthanized—relocation is often restricted because it can spread disease. Professional operators must obtain permits for certain methods. Homeowners should verify that their pest control company holds the necessary licenses and follows state guidelines.
Health and Safety Concerns
Squirrel infestations pose several health risks. Their droppings and urine can contain leptospira bacteria, which causes leptospirosis—a flu-like illness that can lead to kidney damage. Salmonella is also present in squirrel feces. Inhaling dust from dried droppings can expose you to histoplasmosis, a fungal lung infection. Furthermore, squirrels carry fleas and ticks that can transmit diseases like Lyme disease and tularemia. When squirrels die in walls or attics, the decomposition attracts flies and beetles, creating a secondary pest problem. Always wear gloves and a mask if cleaning up droppings, or hire a professional. Squirrel Removal technicians follow OSHA protocols for biohazard cleanup and can sanitize affected areas.
How Nevada Properties Should Prepare for squirrel Service
Before a professional visit in Nevada, clear access to baseboards, utility areas, kitchens, bathrooms, garages, crawl spaces, and any location where activity has been seen. Take photos of sightings, save damaged materials when safe, and note when the problem is most active. This helps the technician confirm the species, find nesting or entry points, and choose a treatment plan that matches the property instead of relying on a generic spray-and-leave visit.
Questions to Ask Before Booking squirrel Control
Ask whether the inspection is included, what treatment methods are being proposed, how follow-up visits are handled, and what conditions could change the price. For rental properties, restaurants, hotels, warehouses, and multi-unit buildings, ask whether documentation is provided after service. Strong providers explain the source of the problem, the treatment area, safety instructions, and prevention steps in plain language before work begins.
What Makes Nevada squirrel Problems Different
Nevada properties can have different pest pressure from block to block because of building age, landscaping, moisture, trash handling, nearby food sources, and how tightly entry points are sealed. A good inspection does not assume every property needs the same service. It checks the structure, surrounding conditions, activity level, and safety needs before recommending treatment.
Inspection Steps for squirrel Issues
A complete inspection should look at interior activity, exterior entry points, moisture conditions, food or harborage sources, nearby vegetation, storage areas, and any connected units or shared walls. The best inspection notes where activity is confirmed, where it is suspected, and what needs to change after treatment so the same issue does not return quickly.
Follow-Up and Prevention Plan
Professional pest control should not stop at one visit when the infestation risk is ongoing. Follow-up timing depends on the pest, severity, season, property type, and whether sanitation or exclusion work is still needed. A practical prevention plan may include sealing entry points, improving drainage, trimming vegetation, changing storage habits, and monitoring activity after service.

When to Call a Professional
If you hear consistent activity, find droppings, or see damage, call a professional immediately. squirrels reproduce quickly—two litters per year of 2–4 young each—and a small problem can escalate into a colony. Do not seal entry points without first removing the animals, as this can trap them inside to die and decompose. A licensed wildlife control operator will perform a thorough inspection, humanely remove the squirrels, and seal all gaps. Squirrel Removal offers inspection terms that vary by provider and a service guarantee—call +1 888 546 7983 today.
DIY vs Professional
DIY squirrel control often fails because homeowners cannot identify all entry points or may handle the problem ineffectively. For example, sealing a single hole while squirrels are inside can cause them to chew new exits. Poisons are illegal for squirrels in many states and pose risks to pets and children. Professionals use one-way exclusion doors, which are humane and proven. They also have the training to safely handle droppings and repair damage. While a DIY approach might save money upfront, a pro’s exclusion guarantee typically pays for itself by preventing repeat invasions. For a one-time, guaranteed solution, invest in professional service.
Local Context
Nevada spans two distinct ecosystems that influence squirrel activity. In the northern half—Reno, Sparks, Carson City, and Lake Tahoe—Eastern gray squirrels dominate. They thrive in neighborhoods with mature oaks, pines, and elms. Homes here often have wooden eaves and attics that provide easy access. The Sierra Nevada foothills see heavy snowfall, and squirrels will invade attics in October–November as temperatures drop. In southern Nevada—Las Vegas, Henderson, and Boulder City—rock squirrels are more common. These ground squirrels burrow under foundations, sheds, and patios, causing structural issues. They are active year-round but breed in spring and summer. The urban heat island effect in Las Vegas can push squirrels into shaded attics during June–August. Climate variation means exclusion timing differs: in the north, seal before October; in the south, seal before April and again before August. Major metro areas like Reno and Las Vegas have high squirrel densities; rural areas (Elko, Ely) see fewer but still problematic infestations near agricultural feed stores. For city-specific help, contact Squirrel Removal for a inspection terms that vary by provider tailored to your location.
Prevention Tips
- ✓Trim tree branches so they are at least 10 feet away from the roofline.
- ✓Install chimney caps with mesh that prevents entry.
- ✓Seal all gaps larger than 1/4 inch with steel wool, caulk, or hardware cloth—squirrels can squeeze through 1.5-inch openings.
- ✓Cover attic vents and soffits with heavy-gauge metal screening.
- ✓Remove bird feeders or place them on poles with baffles; squirrels love free food.
- ✓Inspect your roofline, eaves, and fascia boards annually for signs of gnawing or holes.
💡 Did You Know?
- ★squirrels use elaborate fake-burying tactics to fool food thieves—they dig a hole, pretend to drop an acorn, then cover it up, even if they still have the nut in their mouth.
- ★They can rotate their ankles 180 degrees to climb down trees headfirst, a feat few mammals can perform.
- ★a squirrel’s front teeth never stop growing; they wear them down by gnawing on hard objects like nuts and—unfortunately—your home’s wiring.
