Our neighbors had originally had their house sealed by AZ Best and had great results. After seeing a few scorpions in our house, we decided to do the same. AZ Best is professional, courteous and reliable. They are affordable and will come back, if needed, for a second dose of spraying. Once we had our house sealed by Jim, we saw the last few nasty scorpions in our house and haven't seen one since. Our service tech is Jeremy, and he is the best. Calls the day before to let us know he'll be by, lets us know the time, does a thorough job and answer any questions we have. Definitely worth the price to keep critters away.
