Spiders from Mars

I hesitate to mention this. I don't want to sound paranoid or anything but I think my spiders are ganging up on me.
So far we have lived in relative harmony. I see them in all the corners of the castle and I let them be. I don't see any sense in killing them just because they're there. Yeah, so they can be a little creepy when they jump out in front of you on the bathroom sink, or hanging in front of your face as you walk into the bedroom, but hey, I'm willing to share my space. I also assume that we have common enemies of the annoying flys and mosquitoes and that my spiders are doing their best to keep these pests in line so that I am less bothered by them.
As of this morning I am suspicious that they are stepping out of their corners and feeding on me. Besides all the huge bite marks on my arms, legs, and elswheres, I found myself walking through spider webs that spanned my hallways and even across my living room. Now are these guys working overtime to keep up with the pest population or am I dinner?
I don't plan any rash retaliation yet. I am willing to lay low and let them work, as long as it's not on me. I will, however, have my guard up.
I may only have two eyes but they are open.
One spider looks at me sideways and it's...
Bam Bang, to the the Moon!
