Picnics, camping and other summer outings increase your chances of encountering stinging and biting insects. According to the American Academy of Allergy, Asthma & Immunology (AAAAI), nearly 5 percent of Americans may be at risk for life-threatening allergic reactions to insect stings.

"For most people, getting stung results in temporary pain, redness and swelling at the site of the sting. However, for those with allergies to insect stings, it can result in a sudden, severe reaction called anaphylaxis. This may be fatal if not treated immediately," Dr. Clifford M. Tepper of the AAAAI said in a press release.

Some people may have allergic reactions to saliva or venom released in the stings of bees, yellow jackets, hornets, wasps and fire ants. Treatments for insect allergies include allergy shots known as venom immunotherapy. The treatment can dramatically reduce the chance of a life-threatening reaction. Physicians may also prescribe epinephrine, a medication that patients can use to treat themselves during an emergency.

Added Tepper: "Symptoms of anaphylaxis to watch for include: itching and hives over large areas of the body, separate or away from the site of the sting; swelling in the throat or tongue; difficulty breathing; dizziness; stomach cramps; nausea and diarrhea. If you suffer from a stinging insect allergy, you should take extra precautions to avoid being stung."

However, many people may not be aware they have insect sting allergies until they have been stung. Experts recommend familiarizing yourself with the appearance of insects that may cause allergic reactions. These insects include:

• Yellow jackets. Flying insects that are black with yellow markings. They are found in various climates across the United States.

• Honeybees. Flying insects with fuzzy bodies that are covered in dark brown and yellow stripes.

• Paper wasps. Flying insects with slender, elongated bodies that may be black, brown or red with yellow markings.

• Hornets. Flying insects with black or brown bodies and white, orange or yellow markings. They are larger than yellow jackets.

• Fire ants. Crawling insects that are reddish-brown in color and live in mounds in warmer climates.

To avoid stings, the AAAAI recommends the following:

• Try to avoid the insect's territory or nest. Many of the insects are more likely to sting if their hives, nests or mounds are disturbed.

• If you encounter a stinging or biting insect, move away slowly and don't panic. Do not swat at them.

• Avoid wearing perfume or brightly colored clothing because this may attract some insects.

• If cooking, drinking or eating sweet beverages or foods outside, be aware of nearby insects. Try to keep these items covered.

• Avoid wearing clothing that is loose-fitting. This may increase the chances of insects becoming trapped between the clothing and your skin.
