Ahwatukee is a scorpion hot spot for some reason. I've gotten used to them. We averaged three/week inside the house when we first moved here. I took the fight outside and started going out every night with a black light when the weather warmed up. Years later, it's very rare that we find more than a couple inside over a summer.
This was a pic I took in 2008 or so when I went out for the first hunt of the season. There were >20!
