I've had them for quite a while now (several years now I think) to help me make sure I never have to deal with termites and to help keep my house bug-free. I've never had issues with pests in my home, and the single time I saw ants (quite a long time ago), their response was immediate. Their techs are very knowledgeable, and my current tech (Rich) is also very professional and provides great service and I appreciate that he cares about my pets health and well-being by making sure to let me know how long I should wait before I let them out.
