Field-tested research on scorpion behavior, building envelopes, and urban pest ecology: from raw data to published findings.
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.
Collected 1999 to 2025.
Across the greater Phoenix metro.
Population-adjusted observation data.
Season by season, not just summer.

1999-2025How bark scorpions live, move, and spread: prevalence, distribution, and the behavior behind the encounters.
The home as a system: how building performance and envelope integrity determine scorpion risk.
From generic treatment to prescriptive control: frameworks for managing pest risk on evidence.
Heat, growth, and infrastructure: the forces that move pest pressure across a desert city.

Pest Risk ManagementFrom Generic Treatment to Prescriptive Risk Management: A Framework for Scorpion ControlWe lead with evidence, explain the why, and make expertise genuinely useful, not decorative.
A home is a system. We study relationships and root causes, not isolated symptoms.
Every finding is written to be understood, trusted, and acted on by the people who live with it.
We weigh effective protection against responsible, proportionate ecological choices.
