What is a scorpion?

Scorpions, found in southwestern Canada and throughout the United States, are up to 7.5 cm (3 in.) in length. They have eight legs and a pair of pincers like a crab has. The stinger, which injects venom, is located at the end of a narrow tail that curves around and over the back of the scorpion's body. Although some scorpions are not poisonous, others have venom strong enough to kill a person.

Some scorpions are found in cool, damp places, such as basements, junk piles, and wood piles. Other scorpions are found in desert areas.

How is a scorpion sting treated?

Home treatment

• Put ice or a cold pack on the area for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin.
• Try an over-the-counter medicine for itching, redness, swelling, and pain. Be safe with medicines. Read and follow all instructions on the label.
• Take an over-the-counter antihistamine, such as diphenhydramine (Benadryl) or loratadine (Claritin), to help calm the itching or swelling.
• Don't scratch or rub the skin around the area.
