This is the biggest kitchen slug that I have despatched so far. I came this close "<-------->" to treading on it the other night - in my bare feet.
You should have seen it at full stretch - when it was going across the floor in full power mode. He was probably 50% longer.
One teaspoon of salt, and it's game over.
Note the slime trail that it's leaving behind. I'll have to try to photograph the web of trails that appear on the lino floor each night.
