Stinging Insects
Insect stings are responsible for inducing severe allergic reactions in at least 1-2 million people in the U.S. An estimated 3% of the population is susceptible to allergic reactions caused by insect stings, including those of yellow jackets, honeybees, paper wasps, hornets and fire ants.

For a small number of people, these stings can be life-threatening, resulting in anaphylaxis. Symptoms may include itching and hives, swelling of tongue or throat, breathing difficulty, dizziness, and intestinal issues. In severe case, a rapid fall in blood pressure may result in shock and loss of consciousness.
