We've been using Bulwark for years. Cory is professional, courteous, and highly knowledgeable. I pay for every other month service. If I have any problems in between treatments, Cory comes out and takes care of it-whether it's a cockroach, a hornet nest, or a rat-for free! One time, my neighbor's house was INFESTED with black widow spiders. Thanks to Bulwark, we didn't have a single black widow, but Bulwark came out and checked just to make sure. That's the level of service they provide. It goes way above and beyond.
