On February 14, 2023, EPA released a compliance advisory regarding pesticide devices regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”).  EPA released the advisory in response to “substantial non-compliance with FIFRA in the device and pesticide marketplace. Examples of non-compliance include unregistered pesticides claiming to be devices, devices bearing false and misleading statements, and devices being sold and distributed that were not produced in an EPA registered establishment.”  While the compliance advisory provides a helpful overview of requirements applicable to pesticide devices, it does not provide new substantive guidance, including on key questions facing many device manufacturers and distributors.  The advisory also suggests that EPA may increase its enforcement efforts in this area, so companies producing devices (or products that may arguably be devices) should consider taking proactive steps to ensure their product lines comply with FIFRA’s requirements.
