Environmental Groups Ask Regulators to Ban Some Rat Poisons

Environmental groups are asking state regulators to ban rat poisons known as second-generation anticoagulants. The groups are concerned that the poisons are also killing other animals.
You can buy second-generation anticoagulants at hardware stores; one common brand name is d-CON. Greg Loarie, an attorney with the non-profit group Earthjustice, says the wide availability is one problem. The other is that they don't just kill rodents.

"These second-generation anticoagulants are really long-lasting," Loarie says. "The target animal, the mouse or rat, can eat this poison and be eaten by a predator and the predator then becomes poisoned."

Loarie says dead animals that have tested positive for the poison include eagles, falcons and the endangered San Joaquin kit fox.

Earthjustice and other groups sent comments to the Department of Pesticide Regulation, asking it to deny renewals for those pesticides. All pesticides come up for annual renewal in California at the end of the year.

The Department of Pesticide Regulation is studying the impact on wildlife. The EPA is also looking at the issue.
