Water vole management - Could anticoagulant rodenticides stereochemistry mitigate the ecotoxicity issues associated to their use?

•Cyclic explosions of water voles cause major damage to grasslands in mid-mountain.•Bromadiolone is used for their control leading to wildlife poisonings.•Trans-bromadiolone is the only responsible for the ecotoxicity of bromadiolone.•Cis-bromadiolone is a good compromise between efficacy and ecotoxicological risk.•Modeling is used to favor the modification of new baits.
