Rodenticides

Please help us expand this page!

Overview

Rodenticides are a broad class of chemicals designed to kill mammals, particularly rats and mice. Compounds that inhibit blood clotting, called anticoagulants, are commonly used to control rat populations. One of the first rodenticides was warfarin, a anticoagulant related to the plant-derived coumadin from spoiled sweet clover. In the 1950s rats developed resistance to warfarin and development of more potent anticoagulants began.

Other rodenticides contain flouroacetic acid, zinc phosphate, and thiourea-based compounds.

The primary alternative to rodenticide use is trapping.
