I have had an overall positive experience with Bulwark. I appreciate they do not charge for call backs when needed. They helped me eradicate carpenter bees, and we also use them for our 8 week maintenance treatments. My recent technician, Robert Haynes was flexible and very understanding with my challenging schedule and special needs within our house. I only knocked 1 star off because their corporate billing system is wonky sometimes, however that is irrelevant for me since the service is good.
