First of all, I love Bulwark! When all, literally all my neighbors and friends had ants invade their homes late in the summer. I did not see any. Zero spiders, zero ants, and only an occasional dead roach. Our new tech was very polite like all the others. He waited until I cleared the toys out back. ;) His name is Robert Carpenter and he was thorough and careful with the hoses. (I like my plants not to be broken.) Overall a great experience each time and I will never stop using them. Customer for life!
