The six-inch Arion vulgaris is resistant to slug pellets and can consume up to 20 before it dies and now experts are saying drowning them in pints of beer could be the only way.

A slug expert told The Mirror newspaper the slugs love the taste and are prone to crawling into a puddle of it and dying.

The slugs are highly-fertile and they are mating with the British breed to produce super-hybrids which can survive hot and cold temperatures.
