So does the bag of wool pellets come with a catapult to use to fire them at the slugs? 
What I could see happening is the Blackbirds weighing in, rooting around in the wool pellets and chucking them out of the pots as they look for insects and worms underneath them. Every time we put the garden compost on our beds the Blackbirds just hurl it across the lawn. However they sing so beautifully I can forgive them anything.
