​A March heat wave is already changing pest activity across Arizona—and it’s happening earlier than usual.

Locals are seeing a surge in both rattlesnakes and scorpions as temperatures climb ahead of schedule. But while both are active, scorpions pose a different kind of problem for homeowners.

They don’t just stay outside.

They come inside homes.

For homeowners across Arizona, this is exactly when scorpion problems start showing up—and it’s something Northwest Exterminating has been helping solve since 1990.

​Early Heat Is Driving a Surge in Scorpion Activity

A recent headline says it plainly: March heat wave kickstarts early rattlesnake, scorpion surge across Arizona.

This isn’t just about one pest—it’s about how quickly rising temperatures are accelerating activity across the board.

Locally, the impact is already being measured. The Banner Poison and Drug Information Center in Phoenix has already reported more than 200 scorpion sting calls so far this year.

That’s a strong signal that scorpion season isn’t just early—it’s already underway.

Why Scorpions Are Showing Up Earlier This Year

Scorpions follow temperature patterns closely. When the weather heats up earlier than usual, their activity ramps up earlier, too.

That means:

  • Longer scorpion season
  • Earlier home invasions
  • More opportunities for them to settle around your property

If you normally don’t think about scorpions until summer, this year is different.

They’re already moving.

Why Your Home Is a Target

Scorpions aren’t trying to bother you—they’re just looking for three things:

  • Food (other insects)
  • Water (even small moisture sources)
  • Shelter (cool, dark hiding spots)

Homes provide all three.

Scorpions can flatten their bodies to squeeze through gaps as small as a credit card. Cracks, gaps under doors, and utility openings are more than enough.

The Bigger Issue: It’s Not Just One Scorpion

Seeing one scorpion usually means there’s more going on.

At the very least, it means your home is supporting the kind of environment scorpions like—usually because other insects are present.

That’s why quick fixes and DIY treatments rarely solve the problem long-term.

They don’t address:

  • Entry points
  • Insect food sources
  • Hidden harborages

What Actually Helps Prevent Scorpions

While DIY treatments fall short, there are prevention steps homeowners can take to reduce risk:

  • Keep outdoor lighting limited or switch to yellow bulbs to reduce insect activity
  • Trim vegetation away from the home
  • Remove woodpiles, debris, and clutter near the foundation
  • Reduce moisture around the home, especially near AC units and irrigation
  • Make sure doors and windows close tightly

These steps help—but they don’t eliminate scorpions on their own.

That’s where professional protection makes the difference.

Why Professional Scorpion Control Matters Right Now

When activity starts early, waiting can make the problem worse.

Scorpions have more time to establish themselves around your home—and once they do, they’re harder to control.

That’s why early-season treatment is one of the most effective strategies.
