Just had my latest service from Anderson. Also will be my last.
Pro: The bugs stay away when they do show up and spray...
Con: They don't call ahead of their appointment time to coordinate. The technician slipped the bill in my door when he was done spraying, except I wasn't contacted ahead of time so I couldn't let him in to spray the back of the house or the inside. I'd consider that less than half a full job. They've also missed appointments without calling to let me know.
When I called to complain and cancel they did offer for the technician to come back and respray but I shouldn't have to micromanage someone to get good, thorough service.
