I myself am very fascinated by bugs and arachnids and other small creatures.
I try to not bother them unless they try to make their home in a place I use a lot (such as closet, or the shelf, or computer desk).
I'm only worried about the insects/vermin/creatures that could potentially carry diseases, I try to dispose of them as quickly as possible. Such as flies, ants, roaches, especially rats and mosquitos.
I don't mind bugs at all. I especially love spiders, they tend to keep the other bugs away, and usually make their homes/webs in corners I don't use at all.
