It's been about 4 to 6 days since second service and I've got moscuitoes in the back. I have a big back yard and I didn't think the sprayer was there for more than a couple of minutes. I could not walk the perimeter of the back let alone the Azaleas in the center in that time. He was in the driveway planning his next appointment (I guess that is what he was doing on his phone)longer than he was at my house. I know I had to ask him to leave do I could get my car out of the garage. If I have to pay more for a big backyard I guess I will. I want/need the moscuitoes gone. I need help. Maybe I shouldn't have switched vendors.
