I've been using Sonoran Pest Control over the past 2 years. I live in a desert environment and we had scorpions everywhere. I used the Kill Zone product at my house and the scorpions are near gone. I've only had to kill 2 all year outside. In previous year I was killing 2-3 a week.
This product and this company delivers quality, and as long as I am living here, I'll continue to use their services.
A++ Company!
