scorpion on the wall...

So I walked into the bathroom the other night and saw a scorpion on the wall....I made Scott come and kill it. Since then, I seem to be slightly obsessed with finding out about scorpions in AZ and how likely it is that one would be able to exterminate them. Turns out my chances of getting rid of all them or keeping all of them out of my house aren't very high. I won't walk barefoot in the house anymore either. And I peer around every corner and turn every light on at night before walking into a dark room...I promise I'm not crazy...I just don't want a scorpion to be lurking around the corner, ready to strike.
