For you guys that treat lawns, do you flag them when finished? In our state, we are not required to flag them, but some of the larger companies do. I generally use dry material and spot spraying, or use a low volume liquid, so a wet lawn is not a major concern like with total liquid apps. I don't think that they are of great benefit to my customer, as I leave them a door hanger with all pertinant information, but was thinking that they may be a good marketing tool. We have a lot of walkers/joggeers, and I was thinking that if they see a nice lawn, and a flag with the co. name, it may be a way to drum up business. Any thoughts?
