Up to an inch long, the bullet ant is among the largest of all ant species. Named for their excruciatingly painful sting, bullet ants are considered to be the most venomous insect. The neurotoxin they use in defense causes severe pain, nausea, and trembling in humans, yet they are not aggressive and only sting if they are threatened.
A bullet ant sting hurts about 30 times worse than that of a wasp.
