The Arizona bark scorpion (Centruroides sculpturatus) is the most venomous scorpion in North America — and it lives right here in your backyard. While most scorpion stings in the world cause only local pain and swelling, a bark scorpion sting is in a different category. Its venom is a complex neurotoxin that can cause intense pain, numbness, tingling, muscle twitching, difficulty swallowing, blurred vision, and in severe cases, respiratory distress. Arizona Poison Control handles thousands of bark scorpion sting calls every year. So yes — they can be deadly, particularly for young children, the elderly, and anyone with a compromised immune system or respiratory condition.
That said, deaths from bark scorpion stings in the United States are extremely rare in the modern era, largely because antivenom (Anascorp) is widely available at Arizona hospitals. The real danger is not instant death — it is the severity of the neurological symptoms, which can be terrifying and require emergency care. Children under five are at the highest risk because their smaller body mass means the venom is more concentrated. Pets, especially cats, are also highly sensitive to bark scorpion venom. If you or a family member is stung, call Arizona Poison Control at 1-800-222-1222 immediately and seek emergency care if symptoms are severe.
The best protection is prevention. Bark scorpions are nocturnal and hide in dark, cool places during the day — inside shoes, under furniture, in closets, and in wall voids. Professional perimeter treatments create a chemical barrier that kills scorpions on contact and eliminates the insects they prey on.
