We are very happy with Bio-Tech Pest Control. The house is treated once per year and to our amazement, we do not see live pests in the house, if we do, Bio-Tech will come out and reapply treatment to the area we have seen pests. I believe we have used Bio-Tech Pest Control for 5 years and have had them return one time. Bio-Tech treats our out building while here and we only see dead bugs out there, pretty impressive. All of the techs sent to the house to apply treatment are friendly and professional. We are happy customers!
