FACT: The Bark Scorpion (Centruroidies) is the most common type of scorpion in the American Southwest. When it stings, it employs a potent neurotoxin. Pain may last for hours or days. If stung, the best practice is to take pain medication. However if you do begin to have symptoms of agitation and respiratory paralysis, do seek medical attention.
Contrary to popular belief, there has NEVER been a reported fatality in the United States from a Bark Scorpion sting.
