Vespula venom

Vespula venom, produced by common wasps like yellowjackets, contains proteins that cause pain, swelling, and allergic reactions. When a wasp stings, it injects venom that affects nerve endings, leading to a burning sensation. The venom also triggers the body’s immune response, which can result in redness, swelling, and, in sensitive individuals, more severe allergic reactions such as anaphylaxis. The venom's components include enzymes and toxins that can damage tissue and stimulate inflammation. Understanding its effects helps in managing stings and recognizing allergic reactions promptly.
