Non-target exposure to anticoagulant rodenticides (ARs) has been documented globally, however there are a lack of studies in the Southeast and a complete absence in South Carolina. Further, research on ARs and mammalian carnivores, like bobcats, is limited, making the Clemson Rodenticide Project even more valuable.
Here are some studies that show research into the presence of ARs detected within non-target wildlife populations.
Studies in the Southeast
