Scorpion Control

Arizona bark scorpions are the Valley's most feared pest — the only scorpion in the U.S. whose sting is medically significant. They climb stucco, cross ceilings, and squeeze through gaps the width of a credit card.

Peak season: May–September

Signs you have a scorpion problem

  • Sightings at night on walls, ceilings, or in tubs and sinks
  • Finding them in shoes, laundry, or garage clutter
  • Crickets around the property — a scorpion's primary food source
  • Neighbors reporting activity — infestations track street by street

Why Valley homes get scorpions

Bark scorpions thrive in the Valley because our block walls, stucco weep screeds, and irrigated landscaping recreate their natural canyon habitat with better food and water. They hunt at night, glow under ultraviolet light, and can survive months without eating — which is why one-off sprays rarely solve a scorpion problem.

How we treat scorpions

We treat scorpions differently than general pests because standard products don't reliably kill them. Our approach targets where they travel and hide: block-wall voids and fence lines, the foundation perimeter, weep screeds, expansion joints, and entry gaps at thresholds and garage doors. Just as important, we knock down their food supply — crickets and other insects — so your property stops being worth the trip. Monthly service through peak season keeps the barrier fresh in Arizona heat.

For most homes, our Premium plan is the right fit for scorpions — see plans and pricing, published right on the site.

A safety note: this pest is medically significant. If someone in your home has been stung or bitten and shows concerning symptoms, seek medical advice first — then call us.

Prevention tips

  • Seal gaps at doors, thresholds, and garage-door weather stripping
  • Clear clutter, woodpiles, and stored items away from exterior walls
  • Shake out shoes, towels, and laundry left on floors during summer
  • Reduce nighttime insect lighting that attracts their prey

Frequently asked questions

Are bark scorpion stings dangerous?

For most healthy adults a sting is intensely painful but not life-threatening. Young children, the elderly, and pets are at higher risk — any concerning sting deserves a call to poison control or a doctor.

Why do I only see them at night?

Bark scorpions are nocturnal hunters. They spend the day in wall voids, under bark, or in block-wall gaps, then emerge after dark — which is why daytime-only inspections miss them.

Can scorpions really get inside a sealed home?

They can flatten themselves to about 1/16 of an inch — thinner than most gaps around doors, plumbing, and baseboards. Treatment plus targeted sealing is more effective than either alone.
