The best way to tell if it's a brown recluse is to look at it's back.

I have black widows here in Vegas.
Last October, I had 2 big ol' mama's living on each side of my door, and I finally decided I would kill those bitches.
Wouldn't you know it, the day I come home to do so and they disappeared....a cold front moved in the next day.
