First North Carolina does not require posting signs. I do them in part for advertisment, protection from people tracking, and to notify the customer that something was done. They are just generic Pesticide application... please stay off signs with my name, phone, and web address. I got to thinking about doing different signs for different apps. Maybe have a herbicide application, insect or grub application, fungicide application or lime application. It may be more trouble than its worth and i'm not sure I want thousands of each. But I was thinking today... what if I do a lime app on a weedy lawn and put my sign out. I don't want people seing my sign and then not seeing weeds die. What you think?
