Evaluation of aversive agents to increase the selectivity of rodenticides with emphasis on denatonium benzoate (Bitrex) bittering agent
Aversive agents are proposed as potential additives to rodenticides to increase selectivity to the target species. Examples of various aversive agent categories are given, including odorants, tastants, and emetics, with examples of evaluations. Tastant additives have been found that do not interfere...
