First and foremost, we've been going to Snyder's Weed Control since 200, and we have not had to spray or pick a weed once since then. We built a new house and they did an initial spray, and now they come back to spray every six months. I love that it actually works. Second of all, I have a huge lot and the price is much cheaper than I anticipated. I wouldn't go 6 months without calling them, in fact I always feel sorry when I see other people spraying their weeds because we just don't have to. I have already recommended Snyder's to many people.
