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.
