This is my first experience with ChemTec, but it was a great one. Tech Anthony DeCicco was very friendly knowledgeable, and professional. I showed him places in my backyard where poison ivy was growing -- a nightmare for me! He not only sprayed all those places but also checked every inch of the yard to make sure there was no more growing. And he found many other places! I am so grateful to him for his conscientiousness and dedication to doing a first-rate job.
