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.

School of Applied Residential Pest Science

Knowledge is acquired through study. Competence is developed through application.

The School of Applied Residential Pest Science was established by Pest Science Group to advance the professional practice of residential pest management through the coordinated study and application of science.

The School follows a coordinated educational model where scientific study and professional practice advance together.

  1. Study

    Scientific principles are learned through universities, professional organizations, technical literature, PSG instruction, research publications, and independent study.

  2. Observe

    Students observe and evaluate conditions in actual residential environments while developing their understanding of pest biology, building performance, and environmental influences.

  3. Diagnose

    Students learn to identify root causes through structured inspections, analysis, critical thinking, and evidence-based decision making.

  4. Intervene

    Students perform appropriate structural, biological, educational, and environmental interventions under established company standards and professional mentorship.

  5. Evaluate

    Students measure outcomes, document observations, discuss findings, analyze results, and continuously improve professional judgment.

This continuous cycle transforms scientific knowledge into professional competence.

Advancing the science behind pest management.

Science informed

We lead with evidence, explain the why, and make expertise genuinely useful, not decorative.

Systems based

A home is a system. We study relationships and root causes, not isolated symptoms.

Resident focused

Every finding is written to be understood, trusted, and acted on by the people who live with it.

Environment minded

We weigh effective protection against responsible, proportionate ecological choices.

Science in the service of family care.
