Heavy rain and warm spells have provided the perfect conditions for the giant alien pest, which can grow to more than 10cm (4in) long (Thats pretty big for a slug!) and also can produces hundred more eggs than the typical British slug.
The olive green creature is breeding with our own good old British slugs to create powerful, highly fertile super slugs that can outpace and take over from the natives. In the North West of the USA, the hybrid slugs have even been known to be a threat to motorists as they leave behind huge slimy patches of squashed slug when they are driven over, incresed by cannibal slugs devouring their own type.
Slug expert Les Noble, from Aberdeen University, told The Times that the UK was not taking the threat of the super slug Arion Flagellus seriously enough, However DIY chain B&Q has reported a 74% increase in sales of slug pellets and Dr Noble says squashed slugs have been covering the streets of North Wales and upland in the West Country. 'The invasive species is carrying diseases and parasites that are going to wipe out our native slugs', said Dr Noble. 'Our slugs self-fertilise and are so highly inbred they can't keep pace with new diseases and parasites, and together with several other snails may become extinct.'
Another super slug, called Arion vulgaris, has taken a strong hold in parts of northern Europe, such as Norway. They have been eating their way through various crops and its even feared that the invasion could push up the price of chips because of its negative impact on the potato harvest. Organic growers are finding it increasingly difficult to keep the pests under control because they do not use chemicals or pesticides to spray on their crops. All they can do is cut back vegetation around their crops to remove hiding places for slugs and snails, or encourage birds who feed on them.
Have you been affected by super slugs, whats your best tip for getting rid of them? Do you use pellets, or perhaps a beer trap?
