Does this look like a spider bite? TMI

This is on my chest, and it's so gross looking. It doesn't hurt or itch, the skin around it isn't red, there's no fever in it. No puss or anything. It's just a hole. I killed a recluse in my bathroom the other day so I know there has to be more in my house. The hole is bigger than it was yesterday and it's just freaking me out. It's just so freaky looking. Like you can see the flesh in it.
