This depends on the severity of your bed bug infestation. On average, our bed bug treatments take 30 minutes to 2 hours per room to complete. Furthermore, it’s unlikely that all the bed bugs will be killed in the initial treatment, so we recommend two follow-up visits spaced ten days apart. To get an accurate estimate, please call 425-246-9102. We’ll gladly answer this question and any other bed bug questions you have.
