I received a bill that they came - I am just of the mind that I would prefer to be there upon application. I have certain things I want sprayed and just do not feel comfortable that it is as I want it when they arrive and I am not there. I also would prefer a program where I can choose the four months that I want application done - even if it costs me a little more. I would prefer April, June, August and October applications. I just do not see a reason for a mid-winter application. I can not comment on how they did because I was not there. So far I give three stars until I see and experience more - this was my first application after the initial treatment. I will adjust when I see and trust their service with more experience.
