What are insect stings?
An insect sting occurs when an insect uses its stinger on you. The insect may be a bee, wasp, hornet, or yellow jacket. You may have an allergic reaction to the venom.
Stings can happen anywhere on the body. They can be painful and frightening. But most insect stings cause only minor discomfort. The site of the sting may sometimes become infected. Some people who are allergic may have a severe reaction anaphylaxis, which is life-threatening. It can be fatal.
What causes insect stings?
Bees, wasps, yellow jackets, and hornets belong to a class of insects called Hymenoptera. Most stings are from these insects, particularly honey bees or yellow jackets. Yellow jackets are scavengers and are attracted to food at picnics. They can be aggressive when disturbed. Honey bees are less aggressive. But they are attracted to bright colors and perfumes.
Fire ants can sting multiple times. They are often found in southern states. These stings are more likely to become infected.

How are insect stings treated?
Large reactions at the sting site and hives without any other symptoms don’t often lead to more serious generalized reactions. But they can be life-threatening if the sting happens inside the mouth, nose, or throat area. Swelling in these areas can cause problems breathing.
To treat a local skin reaction:
Remove the stinger by gently scraping across the site with a blunt-edged object such as a credit card, a dull knife, or a fingernail. Don’t squeeze or try to pull it out, as this may release more venom.
Wash the area well with soap and water.
Apply a cold pack or ice pack wrapped in a clean, thin cloth to help reduce swelling and pain. Apply it for 10 minutes on and 10 minutes off for a total of 30 to 60 minutes. To make an ice pack, put ice cubes in a plastic bag that seals at the top.
If the sting happens on an arm or leg, keep the arm or leg raised to help reduce swelling.
To help reduce the pain and itching, you can:
Apply a paste of baking soda and water and leave it on for 15 to 20 minutes.
Apply a paste of unseasoned meat tenderizer and water, and leave it on for 15 to 20 minutes.
Apply a wet tea bag and leave it on for 15 to 20 minutes.
Use an over-the-counter product made for insect stings.
Apply an antihistamine or corticosteroid cream or calamine lotion.
Take acetaminophen for pain.
Take an over-the-counter antihistamine, if approved by your healthcare provider.
Watch closely for the development of more serious symptoms. If you have a serious reaction, you need emergency medical treatment right away. Types of treatment you may get in the ER include:

How can I help prevent insect stings?
To reduce the possibility of insect stings while outdoors, try the following:
Limit your use of perfumes, hair products, and other scented items.
Don’t wear brightly colored clothing.
Don’t go outside barefoot and don’t wear sandals in the grass.
Use insect repellent.
Stay away from places where hives and nests are present. Have the nests removed by professionals.
If an insect comes near, stay calm and walk away slowly. Don’t swat away stinging insects, especially yellow jackets.
If you have a known or suspected allergy to stings, you should:
Carry 2 epinephrine autoinjectors at all times and know when and how to use them. These are available by prescription from your healthcare provider.
Wear a medical alert bracelet or necklace with your allergy information.
Wear long-sleeve shirts and long pants when outdoors.
Talk with your healthcare provider about seeing an allergist for allergy testing and treatment. Venom allergy shots (venom immunotherapy) can be a life-saving treatment for people with a venom allergy.
When should I call my healthcare provider?
Get emergency medical care if the sting was in the mouth, nose, or throat area, or if any other serious symptoms happen.
