We live in Surprise (Phoenix area) and would definitely be considered in town. Unfortunately a few years ago we had a scorpion nest in our backyard and I was finding thirty Bark scorpions a night. Luckily through attrition I was able to kill the nest. We then moved away for a few years, but are now back in the same house.
Since we moved back this year we haven't seen many, I was checking on the garden tonight and saw one and decided to go hunting again and luckily I only found eight adult Bark Scorpions.
This is actually one of the things that has concerned me with trying to start a garden and begin practicing things I need to homestead; I'm very worried that any digging I do will just attract more scorpions.
