Top 15 Most Painful Stings in the world (Schmidt sting pain index) 2023

Every species in the world possesses certain defense mechanisms that protect them from predator invasions. From claws to sharp teeth, from horns to stingers, we get to see a diverse list of them in the animal kingdom. Every human on this earth must have been stung or bitten by an insect at some point in his life.

Often, it causes redness with severe itching or pain, but in some cases, it may cause severe allergic reactions and may prove fatal. From the endless list of insects, it is a common query among the general mass as to which insect has the most painful sting.

To answer this, we bring to you a ranked list of the Top 15 Most Painful Stings in the world. The ranking has been made based on their rating on the Schmidt’s Pain Index.
