Perhaps MA is much more liberal in pesticide regulation than other states. Didn't have time to read the whole law, but MA law defines these terms:
""Pest'', an insect, rodent, nematode, fungus, weed, or any other form of terrestrial or aquatic plant or animal life or virus, bacterium, or other micro-organism, except viruses, bacteria or other micro-organisms on or in living man or other living animal, which is declared to be a pest by the administrator or by the department with the approval of the board.
""Pesticide'', a substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest, and any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant; provided that the term ""Pesticide'' shall not include any article that is a ""new animal drug'' within the meaning of section 201 (w) of the Federal Food, Drug and Cosmetic Act (21 U.S.C. s 321 (w), or that has been determined by the Secretary of the United States Department of Health, Education and Welfare not to be a new animal drug by a regulation establishing conditions of use for the article, or that is an animal feed within the meaning of section 201 (x) of such act (21 U.S.C. s 321 (x)).
Basically same definitions as FIFRA, the federal law. Most states regulate the application of pesticides for hire - and they regulate the pesticides allowed within the state. Just because a product has an EPA number does not mean you can use it in your state.
Hometown, and anyone else looking into chemical or alternative pest control, you had better get written confirmation of any regulation or lack thereof before you actively undertake any program. "he said it was OK," or ignorance of the law, is no defense when the law catches up with you.
