Here is a case of pest misidentification that happened a few years ago. A salesman for a very large national pest control company told a prospective customer that she had nematodes in her swimming pool and she needed to have her whole yard sprayed with a nematicide. Fortunately, she didn’t sign a contract and wanted another opinion. She called me and I went to her house and determined she had a swimming pool with small millipedes that fell in. Nematodes are microscopic and you need a microscope to even see them. It is apparent the supervisor was either totally incompetent or a con man. I suspect the former but either is a menace to society.
Misidentification is not the only area where some pest companies are not competent. In another case a pest control technician told his customer that the pesticide he was spraying is so safe you can drink it. When the person told me this, I suggested if he says that again, she gives him a glass and asks him to drink some. I suppose if he did drink it, the industry wouldn’t miss him and society would be better off and it would probably qualify him for the Darwin Award.
Ask for and check references if you have to use a pest control company. If you prefer, you can contact me and I will give you information on how to control most pests yourself. My email address is firstname.lastname@example.org
