An Act a petition that the town of Chelmsford be authorized to ban second generation anticoagulant rodenticides within said town

HD 5546 authorizes the Town of Chelmsford to ban second-generation anticoagulant rodenticides (pesticides used to kill rodents) within its boundaries through local by-law. This bill directly affects Chelmsford residents, property owners, and commercial pest control services operating in the town. It allows Chelmsford to override existing state laws (like Chapter 132B) to prohibit these specific rodenticides, including their use by licensed commercial applicators. The law takes effect immediately upon passage, giving the town authority to regulate rodenticide use locally.
