"A plan to use oral contraceptives to control grey squirrel populations in the UK is making good progress and could soon be put to the test in field trials, say government scientists.
The mass birth control plan involves luring grey squirrels into feeding boxes only they can access, using pots containing hazelnut spread. These will be spiked with contraceptives.
The project could help eradicate the grey squirrel in the UK without killing them, says environment minister Lord Benyon.
It should reduce the "untold damage" grey squirrels do to woodland ecosystems and native red squirrel populations, he says."
