I am experiencing an outbreak of rodents, mostly White-footed Mice and voles. They are moving into barn in large numbers causing damage quickly. No evidence of breeding. They all over the place, even well away from where chickens are kept. Breeding raptors do not even have to fly far from nest to catch what they need so they are overwhelmed. What I did is do a prescribed burn to expose areas already denuded at ground level by the rodents. Will see if the little guys move out.
