Analysis of animal use of "4-Poster", a commercial host-targeted tick control device


In the mid-1800s there were 500,000 white-tailed deer. By 1992, the deer population rebounded to an estimated 18 million. The expanded deer population has facilitated black-legged tick expansion throughout the northeast of the United States which has resulted in an increased incidence of Lyme Disease. The main objective of the USDA-ARS Area-wide Tick Control Project is to manage deer and tick populations, as an effort to reduce the number of ticks, thus decreasing Lyme disease transmission potentials. The “4-Poster” is a host targeted tick control device used in USDA's Areawide Tick Control project in Howard County, Maryland. The device has a bait dispenser surrounded by paint rollers coated with permethrin- based “Tickicide” solution. While feeding, deer will brush against the rollers applying permethrin to their ears and neck. The objective of this project is to help evaluate the use of the "4-Poster" device by deer and non-target animals.
