just bugging

So, I can't remember if I've mentioned this before on here, but I don't like bugs. Not that, but I won't kill them. They scare me, and I don't want any of them flying around my house, or any spiders hanging around, but I can't kill them. I am too afraid that it will hurt them, and not kill them and then they'll have a mortal wound and be in pain. Yeah, I know it's stupid. Rachel told me she doesn't think spiders can feel pain. Not being an etymologist, I really don't know. Insects and arachnoids are not something I have ever studied closely, because I don't care for them and I don't want to know about more than I have to on that front. Anyway, do you think that spiders or insects are sentient beings? Or better yet, do you actually know because you are a science nerd?
