Sven Lagergren of Bralanda said the Spanish slugs, commonly known in Sweden as killer slugs, appeared in the gardens of his cafe, Gula Huset, at the start of the summer and he soon began using an ice scraper to chop the invaders in half, The Local.se reported Monday.
"They've taken over, it's absolute madness! I've killed almost 28,000 this summer," Lagergren said.
The slugs first appeared in Sweden in 1975 and have no natural predators.
"It's this damned weather's fault! It's been raining so much this summer that they're everywhere. Today's quite sunny, I've only killed 100... but on one rainy day I killed 4,700," Lagergren said.
He said he tried putting poison down in the garden, but nothing seems to stop the slugs from trying to ruin his garden.
"What can you do? They don't stop coming! They even eat the ones I've killed. They're disgusting," he said.
