Social wasps thrive in places where humans discard food, so clean up picnic tables, grills and other outdoor eating areas. If a single stinging insect is flying around, remain still or lie face down on the ground. The face is the most likely place for a bee or wasp to sting. Swinging or swatting at an insect may cause it to sting. If you are attacked by several stinging insects at the same time, run to get away from them.
Bees release a chemical when they sting.
This alerts other bees to the intruder. More bees often follow. Go indoors or jump into water. Outdoors, a shaded area is better than an open area to get away from the insects. If a bee comes inside your vehicle, stop the car slowly, and open all the windows.
