Poisonous Ingredient

Wasp venom is poisonous. It is injected into you when you are stung.

Where Found

Wasps carry this venom. Some people are allergic to the venom and have a serious reaction if they are stung. Most people do not need emergency medical treatment if they are stung.

Symptoms

Below are symptoms of a wasp sting in different parts of the body.

EYES, EARS, NOSE, AND THROAT

STOMACH AND INTESTINES

HEART AND BLOOD VESSELS

LUNGS

SKIN

Note: The symptoms marked with an asterisk (*) are from an allergic reaction to the venom, not from the venom itself.

Home Care

For severe reactions:

Call 911 if the person has an allergic reaction (severe swelling or difficulty breathing). You may need to go to the hospital if the reaction is severe.

If you have an allergy to bee, wasp, hornet or yellow jacket stings, always carry a bee 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 sting.

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.

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 increasingly severe.

Symptoms in people who do not have a sting allergy are likely to go away completely within a week.

DO NOT stick 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 wasps are known to congregate.
