We've been using Snyder's for ten years, they do an excellent job. We leave in the summer for several months and come down in the valley once a month. One day we came down and the yard was full of weeds. I had to get out there and start pulling in the hot weather. We heard about Snyder's and called them up right away. In the spring they sprayed the yard. We only had 3 weeds pop up later so I mentioned it to them and they gave it another shot. Everything turned out great and we're pretty happy. It took a lot of work off of me and my wife. I don't think i could find anyone to do it any better to tell you the truth.
