4-Poster and Other Systems for Tick Control On Deer
The 4-Poster Tick Control Device USDA
... The simple device consists of a bin that's filled with whole-kernel corn. Paint rollers on the four corners of the bin are loaded with a special formulation of permethrin that Y-Tex Corporation, in Cody, Wyo., registered with the U.S. Environmental Protection Agency for exclusive application to deer by the "4-poster." As a deer feeds on the corn in the bin, the animal's head and neck rub against the permethrin-laden rollers, which gives sufficient coverage to protect the entire animal.
The 4-poster device offers a viable tick-control alternative to spraying insecticides into the environment that might be toxic to nontarget species. Studies by ARS and cooperators have shown that after two to three years, use of the 4-poster technology will control from 92 to 98 percent of the free-living tick population around the devices

Control Deer Ticks Using Four-Poster Feeding Device to Deliver Safe Pesticide to Deer University of Rhode Island
... Small-scale trials using a novel strategy developed by the USDA called the '4-poster' were recently completed in 5 northeastern states including Rhode Island. Over a 5-year period, abundance of nymphal deer ticks, the stage most responsible for disease transmission, was reduced by over 50% across a 2 square mile area. Now, with funding made available through the Centers for Disease Control and Prevention, the town of Narragansett has the opportunity to put this technology into action on a town-wide scale, to test if this device can reduce Lyme disease incidence.
Systemic treatment of white-tailed deer with ivermectin-medicated bait to control free-living populations of lone star ticks
... Whole-kernel corn was treated with 10 mg ivermectin per 0.45 kg corn and fed at rate of approximately .45 kg/deer per day to white-tailed deer confined in the treatment pasture, whereas deer in an adjacent control pasture received a similar ration of untreated corn. Treatments were dispensed from February through September of 1992 and 1993, and free-living populations of lone star ticks... This study demonstrates that a freely consumed, systemically active acaricidal bait ingested by white-tailed deer under nearly wild conditions can significantly reduce the abundance of all stages of free-living long star ticks. [Use caution when feeding corn, use of goat or deer chow will reduce risks]
See also, Treatment for Lice, Idaho Fish and Game. Ten deer were anesthetized, given orange ear tags and treated with ivermectin (2 ml/100 lb). Marked deer were relocated on monthly intervals and retreated when and if they could be found. Treatment was effective in limiting the extent of the hair loss and reducing lice numbers in these deer.

Acaricidal treatment of white-tailed deer to control Ixodes ... (use of feeding systems for deer to control ticks) July 5, 2011 New York
Deer densities, estimated by aerial snow counts, averaged 22 and 28 deer per km(2) in Bedford and Lewisboro, respectively, over a 3-year period. Significant reductions in tick numbers on deer captured in the treatment area were noted in fall 1999 compared to deer captured at the control site. Drag sampling for nymphal host-seeking ticks indicated 63.6% control in 2001, which dropped to 54.8% the following year, but reached 80% in 2003. Higher-than-normal acorn production in 2001 that likely caused a drop in deer visitation to the feeders may have reduced efficacy against larval ticks in 2002. The 4-Poster effectively reduced the density of Ixodes scapularis, though the level of control is dependent on environmental factors that affect feeding behavior of white-tailed deer..

Efficacy of Amitraz-Impregnated Collars on White-Tailed Deer (Artiodactyla: Cervidae) in Reducing Free-Living Populations of Lone Star Ticks (Acari: Ixodidae) 2012 Journal of Economic Entomology, JM Pound, KH Lohmeyer, RB Davey, JA Miller…
Over a 7 yr period, we monitored the effect of a commercially available, amitraz impregnated anti-tick collar in controlling free-living populations of lone star ticks, Amblyomma americanum (L.) when manually fitted around necks of white-tailed deer, Odocoileus virginianus (Zimmermann). Study animals in treatment and control groups were confined in 38.8 ha game-fenced and densely vegetated treatment plots in South Texas. Tick densities during years 1 and 7 served as untreated pre- and posttreatment comparisons and treatments occurred during years 2 through 5. Reductions in tick densities in the treatment plot were compared against tick densities in a control plot having similar vegetation and numbers of untreated deer. During years of treatment, indices of control pressure ranged from 18.2 to 82.6 for nymphs and 16.9–78.7 for adults, and efficacy, expressed as percentage control during the final year of treatment, was 77.2 and 85.0%, respectively, for nymphal and adult ticks. These data show that acaricidal collar treatments provide efficacies very similar to those achieved with the existing ivermectin-medicated bait and ‘4-Poster’ topical treatment technologies to control ticks feeding on wild white-tailed deer.
