What are stinging insects?

Stinging insects found in the United States include honeybees, yellow jackets, hornets, wasps, and fire ants. While not everyone is allergic to insect venom, reactions in the skin such as mild pain, swelling, and redness may occur with an insect sting.

Who is at risk for insect sting allergies?

Over 2 million Americans are allergic to stinging insects. The degree of allergy varies widely. Most people are not allergic to insect stings, and most insect stings result in only local itching and swelling. Many, however, will have severe allergic reactions. Severe allergic reactions to insect stings are responsible for at least 50 deaths each year in the U.S.

If you are known to be allergic to insect stings, then the next sting is more likely to be similar or worse than the previous sting. Since most stings occur in the summer and fall, you are at greatest risk during these months. Males under the age of 20 are the most common victims of serious insect-sting allergic reactions, but this may reflect a greater exposure to insects of males, rather than a true predisposition.

Allergy to Stinging Insects...Can Be Life-Threatening

When warmer weather arrives, it is time to think about the return of stinging insects. Over 2 million Americans are allergicto stinging insects. While the severity of these allergic reactions varies greatly, they cause up to 150 deaths each year in the U.S. alone.

Stinging insects belong to the class Hymenoptera and include bees, hornets, yellow jackets, wasps, and fire ants. Fire ants, which inflict a painful sting that belies their small size, are most common in the U.S. in the southeastern states, but they may have been introduced to other geographic areas throughout the country. All of the other stinging insects are found throughout the U.S. and Canada.

Most insect stings do not cause an allergic reaction, but simply result in pain, itching, redness, and swelling at the site of the sting. Cleaning the area and application of ice packs to reduce swelling are often the only treatment needed.

Most people who do have an allergy to stinging insects have mild reactions, such as extension of the area of swelling around the sting. In a more serious reaction, a person develops hivesand itching all over the body.
