A proof-of-concept study shows the potential of feeding wild white-tailed deer corn treated with moxidectin, a derivative of ivermectin that eliminates ticks. Deer are key hosts in the lifecycle of ticks—such as the lone star tick (Amblyomma americanum) shown here—and systemic treatment could aid in reducing tick abundances. And, unlike ivermectin, moxidectin in deer meat may be safely consumed with no required delay. (Photo by Susan Ellis, USDA APHIS PPQ, Bugwood.org)
