Wasps when compared to bees, can sting with ease as they can withdraw their sting easily. While being capable of giving a sting with ease and having a more aggressive temperament, they are likely to sting more than once. With wasps stinging multiple times, they inject less venom than a bee would. Depending on the type of wasps, the amount of venom from a sting can vary from 2 micrograms to 15 micrograms. A bee in comparison who will give a single sting will inject around 50 micrograms of venom. The sting apparatus consists of the venom sac and a redundant egg laying tube. The redundant egg laying tube is used as the needle for piercing the skin. Once the needle has pierced the skin, the wasp curls up its abdomen and squeezes the venom sac forcing the venom down the egg laying tube into the skin.
