What are wasps, hornets, and yellow jackets?

Wasps, hornets and yellow jackets are stinging insects. Unlike bees, they can sting multiple times. When they sting, they inject a poison venom, which is sometimes called bee poison. Some people are allergic to this venom, and can have a severe reaction. Symptoms of a wasp, hornet or yellow jacket sting include:
  • Pain, itching and swelling where the sting occurred
  • Low blood pressure
  • Cramps, diarrhea or vomiting
People who are allergic to stings may also have:
  • Swelling of the eyes, throat or mouth
  • Joint pain
  • Dizziness or fainting
  • Rapid pulse
  • Hives
  • Breathing problems
If you are bothered by a wasp, never try to hit or smash it. Some wasps, when killed, can emit pheromones that can alert the rest of the colony to attack.
