Identifying snakes in Idaho

Knowing your location is one of the most powerful tools in snake identification. Many snakes look similar, but the species actually present in Idaho narrows the possibilities dramatically. When you use our snake identifier, factor in your state to boost confidence — and if you ever spot a snake you can't identify, treat it as potentially dangerous and keep your distance.
