University of Idaho Extension: Idaho has three species of scorpion
This page lists 3 scorpions: all from University of Idaho Extension's Homeowner Guide to Idaho’s Arachnids Around the Home and Field, Scorpions section.
University of Idaho Extension says: “Spiders, scorpions, rattlesnakes, and wasps are all venomous.” No official source we use names any of them as dangerous to people. The other 3 scorpions are marked “Not named as dangerous”. That does not make them harmless: do not handle scorpions.
Not every species: no complete official list of Idaho scorpions exists, so this page covers the ones state and Extension sources name. How lists are built.
From A to Z.
Hadrurus spadix

The species list comes from Homeowner Guide to Idaho’s Arachnids Around the Home and Field (BUL 1094), Scorpions section (University of Idaho Extension, September 1, 2025).
Venom labels come only from official sources and link to them; "Not stated" never means harmless. How labels work.
