Arachnid Blues

I am getting tired of being chewed up by spiders. I suspect they bite me in the middle of the night while I'm asleep;because when I wake up the next day, I have a new mark on the left side of my face. 
My mom have tried using spider repellant over and over again, but they just keep coming; it's like they actually enjoy the stuff.

We even tried covering the floor vent, located in the hallway(their entry way), with towels or old sheets that is bathed in pesticide, and yet they still are determined to get inside.
So in protest that I will not take this anymore, I began decrease my chances of getting bitten by killing any spider that is found hiding amongst my belongings.
