Armed with claws and an arched stinger, Scorpions patiently wait to ambush smaller insects at night. There are many species of scorpions native to Nevada, fortunately only one, the bark scorpion, is seriously venomous. Palm trees, piles of rocks, or ground covers are popular shelters for scorpions. They will enter the home through doorways, cracks in walls, and can even be found inside attics.
