Quick -- no Google or Alexa -- what is the deadliest creature on Planet Earth?

Lion? No. Shark? Not even close. Wolf? Nope. Piranha? Rattlesnake? Tiger? Killer whale? Nope, nope, nope and nope.

Those are the most common guesses and they are creatures we're supposed to be afraid of, according to Hollywood.

But the worst killer of humans in the animal kingdom cannot be stopped, and quite often cannot be avoided. There are specific government agencies designed to slow them down, but man's attempts at stopping these creatures so far has been futile.

Experts recommend wearing long sleeves and using mosquito repellent if you are going to be exposed to the creatures, although avoiding them altogether is the best plan.
