When I was around 8 years old I watched an episode of Alfred Hitchcock in black and white on TV. A man was tied up and they showed rats crawling all over him and they were going to eat him. It messed me up and to this day rats are the only creature that really creeps me out.
Bats scare the crap out of me-not wild about rodents either. My daughter had pet rats.
If I had to pick one, I'd have to say botflies. While interesting, they're creepy as hell. The larvae are parasitic to mammals, including one species that is known to infest humans. They burrow into the skin where they grow, eventually emerge, and drop off ready to pupate (which they do in soil.)
I am not exactly fearful of any one of them...but neither do I want them on me!!!
Caped crusaders wearing black witches hats telling cheesy jokes?
Only joking ?
Cockroahes. I can't even stand to see them on television.
Rock spides. They are often identified by their habit of wearing their collar back to front
