SECTION 2. Section 5 of said chapter 132B of the General Laws, as so appearing, is hereby amended by adding at the end thereof the following paragraph:- The department, with the approval of the board, shall by regulation establish a process and standards for the limited use of anticoagulant rodenticides by licensed applicators in public health emergencies, provided that such process and standards provide for one-time indoor use in a single location to address an urgent public health emergency, as determined by the state department of public health and such use shall: (i) be limited to 14 days; (ii) be accompanied by integrated pest management actions that include non-chemical methods and exclusionary measures to control rodents; (iii) require additional labeling of anticoagulant rodenticides used, including but not limited to, the name of the rodenticide clearly labeled on any bait box; (iv) require written rationale for the need for anticoagulant rodenticides over other non-toxic short-term alternatives; and (v) require applicators to report to the department after the 14-day emergency use period and include a plan for ongoing rodent control at the location.
