When summer storms roll into the East Valley, something else shows up with the rain: scorpions. If you’ve spotted more of them in the garage, the laundry room, or along a baseboard, you’re not imagining it. Here’s why monsoon weather sends scorpions indoors, and how to keep them out.

Why Monsoon Season Brings Out More Scorpions

Arizona’s monsoon runs from mid-June through September, and the moisture changes everything for desert pests. For scorpions, two things happen at once:

• Their food supply booms. Monsoon rain wakes up insects. Crickets, roaches, and beetles multiply fast in the damp heat, and scorpions eat all of them. More bugs near your home means more scorpions follow the buffet to your door.
• The rain floods them out. Scorpions spend the day tucked into block walls, burrows, and debris. When storms soak those spots, they climb to the surface looking for somewhere dry, often your garage, entryway, or bathroom.

They also become more active as a storm approaches, so a rainy week can bring a real jump in sightings.

The Bark Scorpion Is the One to Watch

Most Arizona scorpions give a painful but minor sting. The one to respect is the Arizona bark scorpion, the state’s only dangerous species, and a climber that squeezes through gaps as thin as a credit card. During storms, it likes to tuck into shoes, towels, and bedding, so shake those out before using them. 

If someone is stung and reacts badly, especially a child, older adult, or pet, call the Arizona Poison and Drug Information Center at 1-800-222-1222.

Find Them Fast: The Blacklight Trick

Here’s a useful trick for peak scorpion season. Scorpions glow. Their shell has a thin outer layer, the hyaline layer, that holds fluorescent compounds, so a cheap blacklight makes them light up bright blue-green in the dark. According to Arizona State University, nearly every scorpion species does this, and even shed skins glow.

To hunt them, head out after dark with a UV flashlight and scan slowly along the ground, your foundation, and up the walls. Check the garage, closets, and baseboards indoors too. A glowing scorpion stands out from several feet away.

A blacklight only finds scorpions; it doesn’t keep them out. UV doesn’t repel them. And scorpions are tough, hiding in tiny cracks and shrugging off many store-bought sprays, so a single do-it-yourself treatment rarely holds through a full monsoon. Finding them is step one. Keeping them out is the real work.

How to Keep Scorpions Out This Monsoon Season

A few steps make your home much harder to enter, especially when the rain is pushing scorpions your way:

• Seal the gaps. Weatherstrip doors, pack weep holes with steel wool, and screen your vents. Scorpions fit through cracks as thin as a credit card.
• Clear the perimeter. Move woodpiles, rocks, and soggy debris away from the house; these are prime hiding spots.
• Handle standing water. Fix drainage and dump pooled water so you aren’t breeding the insects that scorpions come to eat.
• Cut off their food. Keeping crickets, roaches, and other bugs down starves scorpions out.
• Switch to yellow bulbs. They draw fewer insects toward your doors and windows.

Because scorpions are so hardy, the most dependable results come from steady, recurring treatment, not a one-time spray.

Scorpion and Monsoon FAQs

Why do I see more scorpions during the monsoon season?

Two reasons. Monsoon rain booms the insects scorpions eat, and it floods their outdoor hiding spots, pushing them toward the surface and into homes for dry shelter. More food and more displacement mean more sightings.

Does a blacklight keep scorpions away?

No. A blacklight only helps you see scorpions, since they glow under UV. It doesn’t repel them, so use it to find scorpions, then seal entry points and treat the perimeter.

How much does scorpion control cost?

At Affordable Pest Control, recurring plans start at $75/month for VIP, $54/visit for Concierge, and $199 per service for one-time Flex treatment. For scorpions, recurring service is usually the better value, since they need steady pressure to keep out.
