Targeted poisons rodenticides

Shivanandappa, T., Ramesh, H.P., and Krishnakumari, M.K. Rodenticidal poisoning of non-target animals acute oral toxicity of zinc phosphide to poultry, Bull. Environ. Contam. Toxicol, 23(4/5) 452-455, 1979. 

The use of odors to reduce the contrast of the novel bait container with other feeding points within the arena reduced the time taken to control rats under these stable experimental conditions by 55%. This time is similar to that observed when the environment is unstable. These results therefore suggest that neophobia will not constrain the effectiveness of a rodenticide treatment, where the food supply is unpredictable or where the novelty of the rodenticide bait and its container has been masked by an odor familiar to the rat. If the efficiency of treatment with rodenticides in undisturbed field habitats such as grain stores can be similarly improved with this technique, then we may also observe a concomitant reduction in the risk of poisoning to non-target wildlife.
