they all sting. Bees would be the most painful, since they inject more venom into the wound when they sting you. The other three are capable of stinging you repeatedly without losing their stinger so that can suck too but if you're asking which individual sting is more painful it's the bee. When a bee stings you it's whole abdomen gets ripped from its body (the abdomen is full of the poison that makes the sting really hurt) and all that poison goes into one sting. When the other three sting you they inject only a small portion of their poison into you but do not die so they are more likely to sting.Does all of the following sting or bite, wasps, hornets, bees, yellow jackets and which is the most harmful?
