Michael was very professional and pleasant to work with. I will have to wait to see how effective the spray was. He didn't use the long hose with the sprayer, just the portable back sprayer. I question whether you get the same coverage with the sprayer that's carried as opposed to the hose sprayer which seems to disperse more spray. This is the first time my entire outside was sprayed with the back carrying portable sprayer so we will see. Thanks!
