I have been using them for three years now. I use them just before the spring because they spray the two trees that I have. I like them. They are courteous and prompt. I had a problem with a pine tree in the back and they tried to treat it. However, it didn’t work and the tree has died. It wasn’t their fault, though. So, I will be calling them back for taking the tree out. My neighbor recommended them to me. He has been using them for several years as well. I will continue to use them in the future.
