Clark has alway been very professional in all my encounters with them. I asked about voles in my yard. The QA person cam to my house and did research for me and voles. There is nothing on the market that will get them. The Clark team has been very good about calling me or coming to see me about their efforts. I have been pleased with them in all of my monthly checks, free termites inspections, and quick response when I had an unusual call back. I am pleased with their efforts.
