My 1st service was on March 17th & then nothing. I called on June 1st to inquire why no one had been out for a 2nd round? The woman was super nice & agreed. My service kept getting postponed for some reason. A guy finally came on June 3rd. He was here for about 15 minutes & left just before a torrential downpour. I hope the treatment works, and did not wash away, because there were a lot of clovers.
