I've been using Snyder's Weed Control for about two years now and they are pretty great, I'd say. They have good customer service but what I appreciate most about them is the absolute thoroughness of the work they do. When they say they'll come in and do the yard, they do the entire yard. They are professional, efficient and they take pride in their work. It's a pretty big company, but the owner himself comes out to do the sprays himself. That says something about their work ethic and how conscientious they are.
