Bee stingers stay in; wasp stingers don't. Scrape sideways with a credit card or fingernail to remove a bee stinger. Don't squeeze with tweezers — that pumps in more venom.
Apply a cold pack wrapped in a thin cloth for 10 minutes. A paste of baking soda and water dabbed on the sting helps neutralize bee venom.
Plain diphenhydramine (Benadryl, no decongestants, no Tylenol added) is generally safe for dogs at 1 mg per pound. Always confirm dose with your vet first. Cats: only with vet guidance.
Severe reaction signs: facial swelling that closes the eyes, hives all over, vomiting, diarrhea, weakness, pale gums, collapse, difficulty breathing. Rush to the emergency vet immediately if any appear.
More than a handful of stings is a venom-load emergency regardless of allergy.
Guidance only — in any emergency, call 911.
