Kill spiders in a safe non-toxic way?

[Dee Dee]

I have a huge phobia of spiders and I always find at least 3 of them in my room every other day. Please do not tell me to step on them or squish them because I don't have the guts to. I'm also too scared to pick them up when they're dead since they really creep me out.

What can I make to put in the sprayer to kill the spiders? I prefer the liquid to be clear since I don't want to leave any stain.
I don't want to use any insect repellent that has toxic since I have a kitten and babies (I babysit) at home. Is there anything harmless and non-toxic I can use to kill spiders and prevent them from coming? I've used hairsprays, but some hairspray don't work or are ineffective. Are there any homemade ingredients that are harmless (without toxic) and effective in killing them?
