Bees don't bother humans. Yellow jacket wasps are the pests that dive into your drinks, your food, check your hairspray or anything else that smells good to them. Some people are very allergic to the toxin in a wasp sting and calling for medical help quickly can save a life. For the rest of us, the sting will be annoying for awhile. Other wasps are not as annoying and will usually leave you alone as long as they are not threatened.
