What animals make you cringe?

I actually love leeches, living not in tropics and seeing them not too much helps with that (but I actually seek after them). I find Hippoboscidae quite disturbing because of their elusiveness on your head, they have strange-looking abdomen, they’re almost impossible to kill or just to catch, and somehow I still have zero observations of them. Otherwise I don’t think I don’t like anything, there’re groups you don’t wanna touch you because e.g. they live and eat on carrion or have a big list of possible decieses on them, but that doesn’t make them worse animals, it’s like having a distance between you and a tiger.
