Here’s something absolutely fascinating. Researchers have been studying the idea of using deer themselves as part of the tick-control system for decades. The concept is deceptively simple. Deer eat corn treated with ivermectin. The ivermectin enters the deer’s bloodstream. A tick attaches, takes a blood meal, and now the tick is ingesting the antiparasitic drug too. This is not some brand-new internet concoction. Research involving whitetail deer goes back to the 1990s. One published study using ivermectin-treated corn reported complete control at the target dose, measured by whether exposed ticks were able to successfully produce larvae. South Texas later used ivermectin-treated corn through deer feeders as part of cattle fever tick eradication efforts. That matters because free-ranging whitetails can carry those ticks across the landscape, making the deer both part of the problem and potentially part of the solution. Then researchers in Connecticut took the idea further. During 2021 and 2022, they fed wild deer corn treated with moxidectin, a closely related antiparasitic drug. While treated corn was available, 24 of 29 deer tested, roughly 83%, had blood concentrations considered high enough to target ticks. And here is the interesting biological mechanism. The tick does not necessarily have to be prevented from attaching. It attaches. It feeds. Then it encounters the drug circulating through the deer. The tick can subsequently die, fail to feed normally, or fail to reproduce successfully. Think about the implications of that for a moment. Instead of trying to spray thousands of acres of woods, you potentially turn one of the tick’s primary hosts into part of the control mechanism. That is an elegant bit of biological jiu-jitsu. But nobody should read this and immediately start dumping ivermectin into a deer feeder. Wildlife regulations differ by jurisdiction. Drug residues matter. Withdrawal periods matter if the animal may eventually become venison. Researchers also have to consider possible effects on dung beetles, insects, scavengers, other wildlife and the ecological ramifications nobody has discovered yet. The science is intriguing. The implementation requires circumspection. Still, the idea that the animal carrying the ticks could simultaneously become the mechanism that suppresses them is exactly the kind of environmental biology that gets my attention. Sometimes the most interesting solutions are not about fighting nature. They are about understanding it well enough to make biology work for you. #AStoneGroove #SilentMajoritySpeaks
