Living Near Open Desert
Natural desert is home base for scorpions, spiders, and many beetles and crickets. When it is hot and dry, those critters move toward the nearest source of shade and water, which is often your yard.
Homes on the edge of a neighborhood or next to undeveloped lots tend to feel this the most. The back wall and side yards become the front line.
The good news is that desert pests are predictable. They follow the same routes along walls, under gates, and into garages. Once you know those routes, you can block them.
Building a Barrier That Holds
A good barrier is not a single spray line. We treat the base of block walls, the gaps where gates meet posts, the edges of rock beds, and eaves where spiders build. Garages get special attention because scorpions slip right under worn door seals.
We also point out entry points you can fix yourself, like torn weatherstripping or gaps around hose bibs. Small repairs go a long way.

Can you get rid of scorpions for good?
No company can promise zero scorpions in Arizona, but regular treatment plus sealing entry points makes a big difference. Most customers see far fewer of them over time. Our Black Light Scorpion Service can also help by removing scorpions directly at night.
Will you come back if I see spiders after a visit?
Yes. Any time pests show up between scheduled visits, the follow-up trip costs you nothing. Just give us a call.
Do you handle bees or wasps?
Yes. We treat for bees and wasps, which sometimes build in eaves, block walls, and irrigation boxes around Maricopa homes. Please do not try to remove an active hive yourself, since Africanized bees can be aggressive.
