To make the bleach and ammonia work, you would have to get it next to the hymenoptera venom, which would in turn require injecting it down the wound tract...please do not do this-these chemicals will damage the healthy cells near the wound and invite an infection. Current medical science does not endorse the use of bleach or cleansers for insect envenomation. Topical cortisone and oral benadryl are effective for local reactions and available otc. If the reaction extends beyond local swelling to generalized hives or airway involvement, get emergency medical help fast, adrenalin and steroids. Infection-cellulitis around the insct bite-is lots scarier than it used to be, cuz the antibiotics are not working anymore.
