Our entire lawn was destroyed by carpenter ants, so we called Pest Zone, after finding them on Homestars. Gancy came out and sprayed everywhere he saw any evidence of the ants. He was very informative and knowledgeable - and spent a long time making sure he sprayed them all. He informed us that due to the fact that it was outdoors, there was no warranty. But he did say if we saw many ants, to give him a call. Unfortunately, we did see several places where they seemed to be re-appearing a week or so later. When we called him, he returned and basically re-sprayed everywhere - at no charge. His customer service is the best! On top of everything else, he is so nice. We would not hesitate to recommend him to anyone who needs his services. Thanks so much again, Gancy.
