Pesticide Safety Information

Each 4-poster deer treatment station device uses a specially-formulated pesticide, 10% permethrin, to kill ticks on deer.  A deer rubs its head and neck against the rollers as it lowers its head to the trough to feed on the corn at the station. This direct contact results in a self-application of the pesticide on the deer. The pesticide is spread over the body during regular grooming activity. 

Although deer treated with permethrin are safe to be handled and the venison safe to be consumed, it is advisable to avoid direct exposure to permethrin.

Gloves should be worn at all times if in direct contact with a treated (pink) deer, or other wildlife, during the pilot study.

  • Permethrin is labeled as “Likely to be Carcinogenic to Humans” and other mammals.

  • Permethrin is not harmful if applied directly to skin, but is toxic if ingested.

  • Permethrin is toxic to fish, and 4-poster devices must be placed away from streams, rivers, and other bodies of water.

  • Permethrin dissipates rapidly if absorbed by plants, soil, and the environment in general. Permethrin use is of little concern for lasting impact on the environment.

More information about this specially formulated pesticide is provided by the U.S. Environmental Protection Agency.
