Henderson sits on the southeastern rim of the Las Vegas Valley, in the heart of the Mojave Desert. Summers are brutally hot, rain is scarce and the landscape looks dry, yet pests are abundant. Irrigated lawns, drip-fed gardens, swimming pools and block-wall fences create small oases, and the creatures that live in the surrounding desert are very good at finding them.
What Henderson homeowners actually see
Desert pests differ from those in wetter climates. Arizona bark scorpions hide in block walls and rock landscaping. Black widow spiders nest in meter boxes, woodpiles and under patio furniture. Turkestan cockroaches, a species common across the valley, are drawn to irrigated yards and slip under doors. Roof rats climb palms and citrus trees, then move into attics. Harvester ants, pavement ants and odorous house ants appear along sidewalks and walls. Crickets, earwigs and sow bugs collect near sprinkler lines, and desert subterranean termites live quietly in the soil.
How the built environment matters
Henderson is a city of master-planned communities, including Green Valley Ranch, Anthem, Seven Hills, MacDonald Ranch, Inspirada and Lake Las Vegas. Homes there usually have stucco walls, tile roofs, concrete slabs and block-wall back yards, with gravel or river rock in place of lawn. Block walls have hollow cores and gaps that scorpions and roaches use. Tile roofs have open eave ends where rats and birds slip in. Drip irrigation lines and pool equipment keep the ground damp in an otherwise dry region, and new construction around the edges of town keeps displacing desert wildlife toward established neighborhoods.
When pressure peaks
- Spring: ants, termite swarmers after rare rains, and spider activity picks up.
- Summer: scorpions, crickets and roaches seek shade and moisture; monsoon storms flush pests into garages.
- Fall: rats and mice look for shelter as nights cool down.
- Winter: milder than most of the country, so rodents and some insects remain active.
What a service visit covers
A technician walks the property, checking block walls, rock beds, garage doors, pool equipment, weep screeds and rooflines. Common treatments include perimeter barriers, dust applications in wall voids, glue boards and traps, bait stations for ants and roaches, and sealing gaps around doors and utility lines. Many Henderson providers also treat the backyard rock and block walls for scorpions, often at night, when the animals come out.
Helpful steps for desert homes
- Replace worn door sweeps, especially on garage and patio doors.
- Keep woodpiles, bricks and stacked pavers away from exterior walls.
- Trim palm fronds and branches back from the roof.
- Run drip irrigation less often near the foundation and fix leaks.
- Wear gloves when handling stored items outdoors.

Are scorpions really in Henderson neighborhoods?
Yes. Bark scorpions live in many valley communities, particularly near open desert and in block walls and rock landscaping.
Does the dry climate keep termites away?
No. Desert subterranean termites live here and use irrigated soil and moisture around slabs.
How often should I schedule service?
Many homeowners choose monthly or bimonthly visits during the hot season. Your provider can suggest what makes sense.
Why do pests enter garages so often?
Garages offer shade, cool air and gaps at the door seals, which is attractive in extreme heat.
