Selected quotes from Wikipedia:
Yellow jackets (Vespula and Dolichovespula) are wasps, sometimes confused with honey bees, especially when flying in and out of their nests. Yellow jackets, in contrast to honey bees, are not covered with tan-brown dense hair on their bodies, they do not carry pollen, and do not have the flattened hairy hind legs used to carry it.
Despite having drawn the loathing of humans, yellow jackets are in fact important predators of pest insects. These species have lance-like stingers with small barbs, and typically sting repeatedly, though occasionally a stinger becomes lodged and pulls free of the wasp's body.
Most of the time, when someone says, "I've been stung by a bee." what they really mean is, "I've been stung by a yellow jacket." These are the agressive stinging insects that provoke much fear among humans. It's unfortunate that "habit" has us referring to them as "bees" because people then carry unjustified fear of honey bees which are generally quite docile. Even standing near a yellow jacket nest, without provocation, can result in a stinging response.
Yellow jackets are cleaver insects that frequently build their nest around a bend from the entrance. This is why you spray and spray at the front entrance and it doesn't get rid of your problem. Your spray is not hitting the nest.
