Scorpion-proofing an Arizona home requires a systematic approach that addresses three things: entry points, harborage areas, and food sources. Entry points are the gaps and cracks scorpions use to get inside. Harborage areas are the dark, cool, protected spots they hide during the day. Food sources are the insects — crickets, cockroaches, spiders — that draw scorpions to your property in the first place. Eliminate all three and you dramatically reduce your risk. Starting outside: inspect and seal all gaps under exterior doors with quality door sweeps rated for pest exclusion. Replace damaged weatherstripping. Caulk around all window frames, pipe penetrations, and utility entries. Install weep hole covers on any brick or block construction. Keep firewood stacked away from the house and elevated off the ground. Remove rock piles, debris, and dense ground cover within 3 feet of the foundation.

In the garage: this is the most common indoor scorpion habitat in Arizona homes. Seal the gap between the garage door and the floor with a quality threshold seal. Check for gaps where the garage walls meet the ceiling and around any utility penetrations. Store items in sealed plastic bins rather than cardboard boxes, which scorpions love to hide in and under. In bedrooms and bathrooms: shake out shoes before putting them on — every time. Keep clothing off the floor. Check under beds and in closets periodically, especially during peak season. Install door sweeps on interior doors that lead to the garage or exterior. In the kitchen and laundry room: seal gaps around plumbing under sinks and behind the washing machine. Fix any dripping faucets or moisture issues — scorpions are attracted to water sources.

The most important room-by-room step you can take is also the simplest: reduce clutter. Scorpions need dark, protected hiding spots, and clutter provides exactly that. Cardboard boxes, piles of clothing, stacked items against walls — all of these create ideal scorpion habitat inside your home.
