why are most people natively scared of tiny rodents and insects like cockroaches, rats, mice etc, even though they are order of magnitudes smaller than ourselves?

Question

Is this phenomenon prevalent in any other species?

In: Earth Science

Answer 1

Are people actually afraid of getting hurt by them or is that they find them to be disgusting? For lost I’ve seen, the fear of things like lizards and rats are different from the fear of things like scorpions and centipedes.

I’m not afraid of roaches, I just don’t want the damn things running in me. The sensation feels incredibly uncomfortable.
