El Paso Scorpion Season: When Bark Scorpions Are Worst

Scorpion season in El Paso runs from late spring through the monsoon, roughly April to September, and peaks in June, July, and August. Warm nights and monsoon rains push bark scorpions and the crickets they hunt straight toward your home, which is when most El Paso families start finding them indoors.

Why El Paso has a scorpion season

El Paso sits in the heart of the Chihuahuan Desert, home to the Arizona bark scorpion, the most venomous scorpion in the United States. These scorpions are cold-blooded and follow the heat. As spring warms up, they become active at night to hunt. As the desert bakes through summer, they move toward the moisture, shade, and prey that homes provide.

El Paso scorpion activity, month by month

April and May: waking up

The first warm nights bring scorpions out of winter shelter. Sightings start slowly, usually outdoors in rock beds, block walls, and around foundations.

June, July, and August: peak season

This is when El Paso families see the most scorpions indoors. Monsoon rains arrive, insect activity explodes, and scorpions follow their food and cooler indoor air. Homes near the Franklin Mountains, along arroyos, and in newer desert developments like far East El Paso and Horizon City get hit hardest.

September and October: winding down

Activity tapers as nights cool, but scorpions that already moved into walls and garages can stay all winter.

Winter: quiet, not gone

El Paso winters are mild, so scorpions do not truly hibernate. They shelter in warm voids, including inside homes, which is why some families still find one in a bathroom in January.

Why they get inside your El Paso home

• They flatten to slide under door sweeps and through weep holes in block walls
• They follow crickets and other insects indoors
• They seek shade and moisture during the hottest, driest weeks
• Rock landscaping and block walls give them harborage right against the house

How to reduce scorpions before peak season

• Seal door sweeps, window gaps, and stucco cracks
• Move woodpiles, bricks, and clutter away from exterior walls
• Reduce crickets and other insects around the home
• Keep outdoor lighting away from doors, since it attracts their prey
• Get a professional exterior barrier treatment before June
