I trust Arrow Pest Control so much they have a key to my house.
I have been using Steve and Arrow Pest Control for maybe 10 years now, and he sprays on a monthly basis. I live in one of the highest scorpion bite areas in the Phoenix valley, and my house backs up to a golf course. I also have a pool, so there is a lot of moisture in the area.
I don't have any problems with scorpions. I hear my neighbors talking about how they have them in their house, but I haven't had one in my house for years. I do see them dead outside, but not in my house, which is my main concern. I wouldn't switch or go anywhere else besides Arrow Pest Control. Steve does a great job.
I am a flight attendant, and I trust Steve so much that he has a key to my house. He comes in to spray whether or not I am here. That shows how much I trust Steve. Also, my neighbors have problems with scorpions, and they don't use Steve, but I don't have any problems. He takes care of my situation.
