I called them because I had a bee's nest at my basement entrance that was keeping the contractors from installing my new heater. The technician/owner came out and was very gruff. He said he could spray them for 100 dollars. Ok. I am desperate as the contractors needed to complete the heater installation, so I agree. He agrees to spray and wait around to make sure any stranglers are taken care of. It is safe to say that not one bee was harmed in his spraying as not one dead bee could be found among the swarm that was still there after just a few minutes of spraying. I told him that they were still there swarming, and it was not safe for me, the contractors, family, or my animals. He asked me, "what do you want me to do, hit them with a fly swatter"? (Might have had better luck than power washing them) I told him I wanted him to do the job he was hired to perform. He said you are gonna pay me the 100 dollars. I will come back tomorrow and spray again. I informed him that no, his company would never ever be used by me again. The contractors were unable to install the heater as the bees were even more aggressive. It cost them time and effort, and me additional money that did not need to be spent.
