Field Data & Case Studies
Where Pest Control
Becomes Applied Science
Field-tested research on scorpion behavior, building envelopes, and urban pest ecology: from raw data to published findings.
Mapping Scorpion Activity Across Metro Phoenix: A 25-Year Field Study
Population-adjusted observation data collected from 1999 to 2025 reveals how scorpion pressure has moved across the Valley. Twenty-five years of field-collected records, gathered into a single long-run picture of activity, heat, growth, and the built edge of the desert.

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?
