Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. If you employ a landscape maintenance company, be sure that they have a commercial pesticide license. State law requires that anyone who transports pesticides to use on their paying job on other people’s property or a government agency that is applying pesticides, including mosquito spraying, must obtain and display decals on the front of their vehicle.
This guarantees that the person you’re paying to apply chemicals in your yard, or who is spraying for the city or county, has been trained and tested. Also, a commercial license holder must have a certain amount of insurance to protect his clients. If you aren’t sure that someone is licensed to perform work, you can go to the Department of Pesticide Regulation website and take advantage of the link they provide that lets you verify someone’s license.
