Boy Scouts, nature lovers and other outdoor enthusiasts alike have something in common: we all come into contact with nasty critters that sting and bite. You don't even really have to be outside all the time to feel the burn from such a bug. Regardless, here are some of the worst stingers in mother nature.

The first that jumps out at you is the bullet ant. This sucker ranks with the highest on the Schmidt Sting Pain Index -- a scale of pain for insects created by an entomologist. Thankfully the ants hail from South America, so I wouldn't worry about stepping on one in your backyard. Either way, I wouldn't want to experience something described as "like fire-walking over a flaming charcoal with a tree-inch rusty nail in your heel."

How about the Tarantula Hawk Wasp. That's three animal names in one! It usually doesn't go after humans, but instead uses its terrible sting to paralyze the infamously terrifying spider. After that, it's all over. The wasp lags narrowly behind the bullet ant in sting-power according to Schmidt's scale. Still hungry for more? Check out the complete list here, if you dare.
