Derrick is awesome!!! I just bought the house I am in and it is in a new development and there is construction of new houses everywhere. I am constantly getting mice, aunts, crickets, and tones of other bugs in my home. As a first time home buyer I take comfort in the fact that when I notice a bug or mice problem all I have to do is call Bulwark and they will send Derrick out to help. I also love the fact that they don't several different people out they send the same person! Derrick is friendly and very informative on special ways to keep bugs out. The best and most reliable people I have ever worked with!!!!!!!
