Allergy to Wasps – Bees and Ants


Allergy to Wasps - Bees and Ants

Hymenoptera stings account for more deaths in the United States than any other envenomation. The order Hymenoptera includes Apis species, ie, bees (European, African), vespids (wasps, yellow jackets, hornets), and ants. Although most deaths result from immunologic mechanisms, some are from direct toxicity.

Anyone can become allergic to bee and wasp stings, but those most likely to become bee allergic are bee keepers, gardeners, and outdoor workers.

Insect stings are more common in children, but children appear to be less likely to experience severe reactions.



1. Localised reactions

Swelling at the site of the sting, and last for more than 24 hours. These reactions are more common in children than in adults.

  • Swelling of throat and mouth
