We've tried these guys a few times, to get rid of scorpions, and it really does not work. Esp. not for $200 +. The second time the guy said he was giving a ""discount"" and looking at my records, it was the same amount that he quoted the first time. The first time he sprayed our house, we got scorpions a month later, and they came again. (It still did not work). I figured since someone recommended them to us, maybe it takes time to work etc. After the second time (we paid) for AZTEC the guy on the phone was unprofessional and rude. I'd avoid them and try someone else. Esp. not for the cost they ask. My attic still has scorpions.
Cons: Ineffective for scorpions, price
