The UK government has given its support to a project to use oral contraceptives to control grey squirrel populations.
Environment minister Lord Goldsmith says the damage they and other invasive species do to the UK s woodlands costs the UK economy £1.8 billion a year.
The bizarre-sounding plan is to lure grey squirrels into feeding boxes only they can access with little pots containing hazelnut spread.
These would be spiked with an oral contraceptive.
Lord Goldsmith says the damage from squirrels also threatens the effectiveness of government efforts to tackle climate change by planting tens of thousands of acres of new woodlands.

Grey squirrels are causing £1.1bn of damage to Britain’s woodlands, the Royal Forestry Society has said, as it recommends they be culled.
The invasive rodents have already caused red squirrels to be wiped from most of the UK by out competing them for food and spreading the lethal disease squirrel pox, but they also destroy forests by nibbling the bark of young trees.
