My husband used City Wide for pre treatment on building pads so I called them for our home. We had the best service man for the first couple years, then a different one every time. I just did not feel comfortable with many of them and I kept calling for resprays. The last guy they sent out was " mr. know it all" refused to spray for ants in the yard because he knew it did'nt work but had a product he could put on the mounds and we should point them out to him. We have an acre and have no idea where they all are. We saw bugs 2 weeks later and are shopping for a new company.
