Tried this and other products from this organization. After weeks of carefully following the instructions and using different products, none of it worked. I was hoping it would as a local exterminator quoted $2,500 a year to control the moles. LOL Local small business owner cleared the moles out in less than a week. Cost, $300 with a 60 day service to ensure they are all dead. So save your money and hire a professional. Much cheaper and less time consuming. But also beware of the sales pitch.
