Our termite damage became worse after the shield was put in place and the quarterly treatments were done. I wanted to go the environmental route, but it didn't work. Worse, no one would call me back to talk to me about the deteriorating situation. The technicians and office staff are friendly, but the management was not responsive and would return calls regarding a refund. This is the worst experience I've had with a business and it resulted in the most the money lost on an investment in my house. We have since used a termite tenting company and we are finding no droppings or new damage. The review would be no stars, if that was an option.
