oh my gosh I know how you feel! But you're braver than me.
Last summer I was talking to some online friends that I have. It was like 3 in the morning and I looked over at my wall and I saw this creepy brown spider. I googled "creepy brown spiders" and came across the Brown Recluse. I don't know anything about them or where they live, but it sure looked like the one on my wall! I was so freaked out I couldn't even kill it. I packed up my laptop and went downstairs and slept in the bathroom!
The next day I sent my brother upstairs and he said he couldn't find it and it was probably dead. A week later I was talking to my friends again and I looked over at my lamp and THERE IT WAS hanging from my lamp. I got hairspray and killed it with that.
I don't think you need to bug bomb your room, but do keep your eyes open. Eek!
