Every person I've dealt with, from sales to customer service to each of the techs, has been friendly and professional and generally a pleasure to deal with. Unfortunately, the actual service has been a waste of money. After multiple retreats of multiple types, we have seen nothing but a slight reduction for a few days before the ants reappear as before. I had been getting the same results with a can of Raid, so I might as well have saved myself hundreds of dollars.
