The United States Environmental Protection Agency has amended its label requirements for certain applications of pyrethroid pesticides. You can read the EPA’s document here.
We have received some inquiries recently about this. To clarify: it is important for California pest control operators to know that the existing regulations from the California Department of Pesticide Regulation still apply and must be followed. In situations where the California regulations are more restrictive than the federal labels, applicators must comply with that state’s regulations.
The U.S. EPA changes were largely adopted to address a situation specific to regions of the country where it is necessary to apply a broadcast spray to vertical surfaces to control certain pests.
