What should you do if you inadvertently disturb a colony and are attacked?
According to the College of Agriculture at the University of Arizona, RUN away as fast as you can. Get to the shelter of a house or car as quickly as possible. Because the bees target the head and eyes, try to cover your head as much as you can, without slowing your progress. Do not flail or attempt to swat the bees, just get away fast. Entering water is not recommended. The bees may wait for you to come up for air.
If you think you have a bee problem, it is best to consult with a seasoned, Arizona professional pest control operator to have them assess the situation and take appropriate actions.
