NOTICE REGARDING RODENT BAITS
Diphacinone treated baits are deemed Federally Restricted Materials by the US EPA and are only available for purchase and use by Certified Applicators (applicators holding a Private Applicator's Certificate (PAC), Qualified Applicator's License (QAL), and/or a Qualified Applicator's Certificate (QAC)).
All field use rodenticide product labels were amended to add the Federally Restricted Use designation. Residential use has been removed from the labels.
Due to this change, diphacinone treated bait is no longer available at the Agriculture Department.
Gas cartridges (smoke bombs) are still available at the Ag Department for ground squirrel control.
