Dogs, hawk and guns are also good for controlling larger pests. Though
even wild owls will help control voles and rats - hence old barns have
nesting access built in; something that may come back into fashion.

Unlikely, all approval schemes require effective control of rodents.
Without food, owls will perish.
With rodents, farms cannot sell their produce easily, if at all.

This is supposed to improve human health, although I have never seen any
recorded problem in recent decades in the UK associated with farm
rodents and *consumer* health.

Tough on owls and raptors, then.
