We experienced an infestation of german cockroaches while using a competitor service for over a year. Although we called the company back on several occasions to complain that their service was not showing any signs of ridding the pests, we called Terminix. We noticed a 95% improvement on their first service. Understanding that it would take at least 3 applications to get rid of the pests, we have not seen not one cockroach after the second application.
