Every Insect Bite That Can Kill You Explained

Nine insects whose bites or stings can kill a person, and what actually does the killing: the venom, the allergy or the germ it carries. From the Japanese giant hornet and the Africanized honey bee to the jack jumper ant, the red fire ant, the rat flea, the sand fly, the tsetse fly, the kissing bug and the mosquito. Every number comes from the World Health Organization, the CDC or a published study.
