Where bark scorpions actually get in
Slab edges, weep screeds, and the quarter-inch gaps that decide whether a desert home stays sealed. A field guide to the entry points that matter most, and the order in which to close them.

Scorpion activity in the Phoenix metro area, 1999-2025
For more than two decades, seasonal field counts, service records, and homeowner reports across greater Phoenix have been gathered into a single long-run picture: how bark scorpion activity moves with heat, growth, and the built edge of the desert. It is the work Pest Science Group exists to share.

The people behind the work.
PSG is a hub for practitioners and researchers working on pests and scorpions in the desert Southwest. It begins with the team at Seal Out Scorpions.
Georgia Clubb
Business Director & Co-Founder · Seal Out Scorpions
A third-generation Arizonan, Georgia co-founded Seal Out Scorpions and champions the program behind the Phoenix activity record. Her focus is the resident's side of the science: making sure the questions studied are the ones families actually live with.

Four commitments behind every finding.
01
Science informed
We lead with evidence, explain the why, and make expertise genuinely useful, not decorative.
02
Systems based
A home is a system. We study relationships and root causes, not isolated symptoms.
03
Resident focused
Every finding is written to be understood, trusted, and acted on by the people who live with it.
04
Environment minded
We weigh effective protection against responsible, proportionate ecological choices.
Would a resident understand it, trust it, and know what to do next?
