After using their service for a full year we still have weeds and the grass still looks miserable. My main concern were the grubs in the backyard. It looked like a minefield after the small animals dug up the grubs for their dinner. After TWO treatments which were an additional cost both times the grubs are still present. Their treatments are ineffective even for simple dandelions however they do return at no additional cost to respray for them. Their customer service reps are also very dismissive when you call in to tell them treatments aren’t working. DO NOT WASTE YOUR MONEY!
