The U.S Department of Agriculture, Animal and Plant Health Inspection Service (APHIS) is preparing an environmental assessment (EA) associated with the Cattle Fever Tick Eradication Program. To manage the threat associated with cattle fever tick infestation, APHIS is proposing to treat white-tailed deer with ivermectin, a broad spectrum anti-parasitic drug, to control tick vectors of cattle fever in Cameron, Hidalgo, Jim Wells, Kinney, Maverick, Starr, Val Verde, Webb, Willacy, and Zapata counties in South Texas.
White-tailed deer would be fed ivermectin-treated corn from a closed gravity feeder placed in areas where cattle fever infestation is a concern. Ivermectin is a widely used anti-parasitic drug in humans, livestock, and pets. Treated corn is placed in the gravity flow feeders from February through July to control cattle fever ticks in deer populations. Each feed site will include one gravity flow feeder. In areas with non-target animals (such as hogs, javelina, or livestock) in the vicinity, feeders will be enclosed with welded wire panels to exclude non-target animals. Human exposure and risk is very low for the general public.
