My dad and his neighbors having been battling with scorpions for some time now. For about a year we were using a franchise pest exterminator. I specifically mentioned we were having problems with the Arizona desert scorpions. They sprayed the inside and outside of the house and we signed up for them to "service" the house every 2 months. I would see 1 or 2 scorpions every few months especially during the summer. I would read other pest control websites about scorpions and they all mentioned how "difficult" it is to rid of scorpions. So I figured the company I was using was doing a good job. My dad's neighbor would complain of scorpions all the time. He finally hired a pest control to come out and help with the infestation. His pest company came out at dusk, sprayed this awful gasoline-like smelling chemical all over the outside of the house and was using black light to catch any running scorpions with a sticky rodent pad. During this visit they found the scorpions running into our backyard. Of course I asked him to come and spray my dad's backyard. The exterminator ended up finding a nest within a stone wall retainer around the garden. Of course I was upset at how ineffective our pest control company "techniques" are.
(...months later) I thought I posted this review months ago! Might as well give a brief update. I found one dead scorpion a couple months after Townsend initial treatment. I'm happy to say the house has been scorpion free and my dad's neighbor hasn't been complaining either. We use Townsend at my dad's house monthly. I would rather pay for the service than a bill from an ER...which has happened to a couple of our neighbors.
