Using Deer Feeders to Control Ticks August 11, 2013 Pennsylvania, Times Leader

System to apply tick control to deer  January 11, 2011 Arkansas Southwest News-Herald 
...ARS researchers have developed new cattle fever tick control measures including this one that automatically applies a pesticide-impregnated neckband to deer ... The Agricultural Research Service (ARS) tackled the tick problem by developing a device called the 4-Poster Deer Treatment Bait Station. This is essentially a corn-filled bin with paint rollers on its four corners. The ARS scientists have since refined their deer treatment station, creating a new system that automatically applies a pesticide-impregnated neckband to wild deer as they feed. The collars can be detached remotely once they've stopped working.

Gibson Island, Maryland, which is a private, resident-owned community, purchased 15 of the devices and deployed them around their community for five years, and achieved at least 77 percent control of the ticks that carry Lyme disease and human monocytic ehrlichiosis, both serious human health problems.
