Insect stings and allergy

Poisonous Ingredient

Bee, wasp, hornet, and yellow jacket stings contain a substance called venom. The venom from each type of insect contains several chemicals. Bee and hornet venom contain histamine.

Of these insects, Africanized bee colonies are very sensitive to being disturbed. When they are disturbed, they respond faster and in greater numbers than other types of bees. They are also much more likely to sting than European bees.

You are also at risk for stings if you disturb a wasp, hornet, or yellow jacket nest.

Where Found

Bee, wasp, hornet, and yellow jacket venom can cause an allergic reaction in some people.

Symptoms

Below are symptoms of a bee, wasp, hornet, or yellow jacket sting in different parts of the body.

EYES, EARS, NOSE, AND THROAT

HEART AND BLOOD VESSELS

LUNGS

STOMACH AND INTESTINES

* These symptoms are due to an allergic reaction, and not venom.

Home Care

If you have an allergy to stings from a bee, wasp, yellow jacket, or similar insect you should always carry an insect sting kit and know how to use it. These kits require a prescription. They contain a medicine called epinephrine, which you should take right away if you get a bee, wasp, hornet, or yellow jacket sting.

Call poison control or a hospital emergency room if the person who is stung has an allergy to the insect or was stung inside the mouth or throat. People with severe reactions may need to go to the hospital.

Before Calling Emergency

Have this information ready:

Poison Control

Your local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. This national hotline will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated. The person may receive:

Outlook (Prognosis)

How well a person does depends on how allergic they are to the insect sting and how quickly they receive treatment. The faster they get medical help, the better the chance for recovery. The chances of future total body reactions increase when local reactions become more and more severe.

People who are not allergic to bees, wasps, hornets, or yellow jackets usually get better within 1 week.

DO NOT put your hands or feet in nests or hives or other preferred hiding places. Avoid wearing bright colored-clothing and perfumes or other fragrances if you will be in an area where these insects are known to gather.
