A Mojave Desert metro that never really freezes keeps pests active twelve months a year. Here are the nine you are most likely to meet in a valley home, and what each one actually takes to handle.
The valley sits in the Mojave, and the climate shapes everything. Summer surface temperatures push past 110 degrees, which drives pests toward the shade and moisture around your foundation. The winters are too mild to knock populations back, so call volume holds steady all year with a hard spike every summer. Add new stucco tracts on freshly scraped desert lots and mature, irrigated landscaping near the core, and you get a pest mix you will not find in most of the country.
Here is the quick version before we go pest by pest:
| Pest | Where it shows up | Peak |
|---|---|---|
| Bark scorpion | Desert-edge homes, garages, weep screeds | March to October |
| German cockroach | Kitchens, apartments, shared walls | Year round |
| Roof rat | Older tree-lined areas, new-build attics | Year round |
| Subterranean termite | Soil under slab foundations | Year round |
| Cricket | Perimeters, garages, near lights | Late summer |
| Ant | Kitchens, irrigated yards, patios | Spring to fall |
| Black widow | Garages, block walls, meter boxes | Warm months |
| Silverfish | Bathrooms, closets, stored paper | Year round |
| Bees and wasps | Eaves, block walls, irrigation boxes | Spring to fall |
This is the one Las Vegas pest with a sting that sends people to urgent care, and it is the reason a lot of homeowners first call. It is most active from March through October, glows pale green under a blacklight, and hunts insects, so it goes where the bugs are. It slips in through weep screeds, garage gaps, and utility penetrations. Control means treating the food source and sealing entry points, not just spraying, which is why scorpion control is its own service.
German roaches are the valley’s worst indoor infestation because they breed fast and hide deep in cracks, wall voids, and appliances. A surface spray scatters them into new harborage and rarely ends the problem. The fix is targeted gel bait, growth regulators, and a follow-up that breaks the breeding cycle. They are heaviest in the older apartment stock and rental-dense corridors, where shared walls let them move unit to unit. That is the job our cockroach control is built for.
Roof rats have spread through the valley’s older tree-lined neighborhoods over the last decade and now turn up in new-build attics and garages too. They climb, so tree limbs touching the roof and unsealed roof lines are their way in. Trapping alone does not last; the exclusion work, sealing roof lines, weep screeds, and garage gaps, is what keeps the next one out. House mice show up the same way and get the same trap-and-seal treatment.
Termites work the desert soil under slab foundations year round and rarely show themselves until there is damage. The warning signs are mud tubes climbing the foundation, hollow or blistered wood, and discarded wings near windows after a swarm. An inspection catches them early, which matters for both your home and any real-estate transaction. Treatment is a liquid soil barrier or a monitored bait system, and inspections run far cheaper than the repairs that follow ignoring them.
Crickets swarm in late summer, gathering around exterior lights and slipping into garages and ground-floor rooms by the dozen. They are a nuisance on their own, but the bigger issue is that they are scorpion food, so a heavy cricket year feeds a heavy scorpion year. Cutting them down with a treated perimeter and warmer exterior lighting quietly reduces the scorpion pressure too. Homes on the desert edge of North Las Vegas see this cycle every August.
Ants are the steadiest year-round caller, drawn indoors by water and food and outdoors by irrigated yards and patios. Most are nuisance ants that a treated perimeter handles well. The key is treating the trail back to the colony rather than wiping the visible ants off the counter, which only sends scouts looking for a new route. They fall under general pest control on a maintained perimeter.
The western black widow is the valley’s most common spider worth taking seriously. It hides in garages, block-wall cavities, and meter boxes, building messy webs low to the ground. The bite is painful and matters most for kids and pets. Control is mechanical first: knock down spiders, clear webs and egg sacs, then treat the harborage. It rides along on the same perimeter plan that handles scorpions.
Silverfish are the small, teardrop-shaped, wriggling insects you find in bathrooms, closets, and boxes of stored paper. They want humidity and feed on starches, paper, and fabric. They are harmless to people but can ruin books, photos, and stored clothing over time. Lowering moisture and a perimeter treatment keep them in check, and they fall under general service.
Stinging insects nest in eaves, block walls, and irrigation boxes, and they become a real hazard when a nest sits by a door or a kid’s play area. A nest near an entrance gets a priority callback because of the sting risk. We handle nest removal and treat the harborage; bees that turn out to be a protected colony get referred to a beekeeper rather than destroyed where that is the right call.
Almost every pest on this list is staging just outside your wall and looking for a way in. That is why the most reliable defense is the same across the board: seal the entry points, treat the perimeter, deny them water, and keep the barrier maintained through the summer push. Homes on the desert-facing edges of Summerlin and Henderson lean on a recurring plan because the pressure off open land never stops. One spray does not hold in the desert; a maintained perimeter does.
It depends where you live. The desert-facing edges of the valley see bark scorpions and crickets first, while the older central neighborhoods deal with German cockroaches and roof rats. Across the whole metro, ants and general perimeter pests are the steadiest year-round callers, with a sharp scorpion spike every summer.
The Arizona bark scorpion is the one with a sting that warrants medical attention, especially for small children and pets. Black widow bites are painful and matter most for kids and pets. Roaches and rodents are health concerns because they contaminate food and surfaces rather than because they bite.
The approach differs by pest, but most are handled under one perimeter plan. Scorpions, ants, crickets, spiders, and silverfish fall under general or scorpion service. Roaches, rodents, termites, and bed bugs need their own targeted methods, which is why no single spray covers everything well.
Scorpions and crickets run from March through October and peak in summer heat. Monsoon storms from July to September push ground pests indoors. Roaches and rodents stay active year round because the valley rarely freezes, and termites work the soil under slabs in every season.
A first general pest control visit usually runs $125 to $200, with recurring quarterly service around $90 to $150. Scorpion control usually starts at $150 to $300, and rodent control with exclusion runs $250 to $600. See the cost guide for the full range by service.
