I called Tru Green Chemlawn to help with some weeds in my yard. They came out approximately every 4 weeks to put on an application. The applications seemed to work pretty good, but I did not like the fact that they called constantly to try to get my to sign up for other services (tree and brush treatment, ant treatment, ariation services, etc). Even when I told them I wasn't interested in these other services, we would still get calls at least twice a week. Next time I need these types of services, I would try to find a different company, one that would not call all the time.
