Scopions: Are They Dangerous?
IMPACT
The effect of a scorpion’s sting depends primarily on the species of scorpion involved. The sting of scorpions in Vaejovis and Hadrurus genera is usually no more serious than stings of ants, bees, or wasps, unless a person has an allergic reaction. Normal reactions include an immediate intense, localized, burning sensation, with little redness or swelling; symptoms usually subside after about 30 minutes. The sting of a bark scorpion, however, can be serious, producing severe pain and swelling at the site of the sting, numbness, frothing at the mouth, difficulty breathing, respiratory paralysis, muscle twitching, and convulsions. These symptoms are signs for the need of immediate medical attention. Especially at risk are children and the elderly. In California, the bark scorpion occurs only in the extreme southeastern part of the state, along the Arizona border.

Anyone stung by a bark scorpion or experiencing an allergic reaction to a sting should seek medical attention. Keep the sting victim calm and relaxed, and do not allow the consumption of alcohol or other sedatives. It may be helpful to apply pressure compression as well as an ice pack to the sting site. Capture the scorpion for identification if you can do it without risking your safety. Antivenins are available to treat severe reactions to stings.
Death from scorpion sting is rare because stinging encounters are uncommon and antivenin is effective. During a 10-month period in the southwest, physicians reported 1,573 cases of scorpion stings. The last reported death in Arizona, where scorpions are common, was in 1948.
