I am very happy with Bio-Tech's service. The technician that serviced the inside of my house was very professional and nice. They did a great job on the outside too. I've had Bio-Tech for 3-4 years since then I have no live bug problem. I do find dead bugs occasionally, but that's one indication that it's working great. I also have peace of mind knowing that they will service my house again anytime I need it at no extra charge. I would recommend Bio-Tech Pest Control to anyone who asks.
