Step-by-Step Guidance
Look for a stinger. Scrape it off horizontally using a credit card or your fingernail. Do not use tweezers.

Clean the sting site with soap and water to wash away surface bacteria.

Apply a cold pack wrapped in a cloth for 10 minutes to reduce local pain and restrict swelling.

Apply calamine lotion or baking soda paste (baking soda mixed with water) to neutralize local acidity.

Watch for signs of anaphylaxis (swelling of tongue/lips, difficulty breathing, rash on torso).
