Most people are not allergic to insect venom, but the pain from an insect sting may make them think they are. Venom from bees, wasps, hornets, yellow jackets, and fire ants could cause an allergic reaction. Understanding the difference between a normal reaction and an allergic reaction might save you an unnecessary appointment with your healthcare professional.

An insect venom allergy, like every allergy, is when your immune system sees venom as a threat and responds by releasing histamine and other chemicals. The release of histamine is what causes your allergic symptoms.
