The problem occurs when some individuals produce excessive quantities of antibodies in their immune system. The excess antibody production usually follows the initial sting to which there is no reaction. However, when the person is stung again, the insect venom entering the body combines with the antibody, produced by the first sting, which triggers a series of internal reactions, resulting in severe allergic symptoms. Whenever stung, try to capture or know the identity of the insect to help doctors diagnose the trouble. When a bee or wasp stings, it injects a venomous fluid under the skin.
Honey bees have a barbed stinger.
Since it takes two to three minutes for the venom sac to inject all its venom, instant removal of the stinger and sac usually reduces harmful effects. Wasps, yellowjackets and hornets have a lance-like stinger without barbs and can sting repeatedly. They should be brushed off the victim's skin promptly with deliberate movements, then quietly and immediately leave the area. Sting Prevention Persons, especially allergic to stings, should practice certain simple precautions to avoid being stung. Some formulations are restricted use.
