This depends on your up-rising for the most part. When I was very young, there was this spider that had its house below my small desk. I grew up accustomed to these spiders and didn't allow my mother to clean them up.

Now, I don't fear spiders and also don't mind them as long as they don't wreak the place with their filaments. I was surprised when a cousin of mine was freaked out by one of them and wanted to insta-kill it.

Now if there is a bug... that's a whole different story. Even though, logically thinking, these beasts are the same.
