Texas Administrative Code Rule §7.30 Classification of Pesticides, was recently amended. A new section, §7.30(d), was added to this rule, effective January 31, 2024. The active ingredient warfarin is now classified as a state limited use pesticide when used specifically as a feral hog (Sus scrofa) toxicant.

Sale of Product

Because the new section classifies warfarin as a state limited use pesticide, a person who sells or distributes state limited use products must hold a current pesticide dealer's license issued by TDA. A person may not distribute a pesticide classified as state limited use to a person not authorized to purchase state limited use pesticides. Additionally, the dealer is prohibited from selling warfarin to a licensee without the applicable category. See below for license category details.

A dealer must keep records of sale or distribution of state limited use products for two years.

Purchasing Product

A person may not purchase a state limited use pesticide unless the person is a licensed pesticide applicator or is working under the direct supervision of a licensed applicator. When purchasing warfarin for feral hog control, the purchase requires the licensee to have the applicable category on their applicator’s license. See ‘Using Product’ below for details.
