6. Kissing bugs

Also known as the “assassin bug,” the kissing bug causes about 12,000 human deaths per year. It spreads the Chagas disease in Latin America through its excrement, which it puts on people’s skin. As we learned from some of the other deadly animals, excrement should just generally be avoided.

But kissing bugs make it difficult to avoid their excrement, because they regularly bite sleeping people right on the face. In fact, this is how they got their charming and misleading name. So while Dementors are purely from J.K. Rowling’s imagination, this kiss of death is very much real.
