But let's be honest here, earwigs are the worst of the worst.

I was told as a kid that those things will climb into your ear and drive you insane.

wait, how come I've never seen or even heard of these things?

but it looks evil indeed.

also about moths, didn't include them because I thought they aren't mainstream enough, but these things are so frigging huge and they just get on my nerves.
