eli5 Why are humans so scared/disgusted by bugs?

This question just popped up in my mind after being scared by the tiniest of spiders. It’s such a universal fear yet it’s completely irrational, in most cases atleast.

There’s very little most insects can do to you, unless you live in Australia lol.

So why are we so scared of something that we can just kill with one slap.

Is it socialisation? Some primal instinct?
