Wasps and hornets, are equipped with a stinger for self-defense and protecting their nest. A wasp’s stinger contains a poisonous substance that’s transmitted during a sting. By burying their stinger, they inject an acidic compound called melittin, which switches on the victim’s pain receptors, and traces of acetylcholine, another chemical that stimulates pain receptors. The initial sensations can include sharp pain or burning at the sting site. The majority of people without sting allergies will show only minor symptoms during and after a wasp sting. You’re likely to develop a raised welt around the sting site. Usually, the pain and swelling recedes within several hours of being stung. The most severe allergic reactions to wasp stings are referred to as anaphylaxis.
