It might not be permanent - it's only stopping slugs which are outside

I'm surprised that you've lost autumn crocus to slugs, mine have given
the best show ever this year and we're certainly not short of slugs.

These are new bulbs. They only arrived and were planted 3 weeks ago.
The same bed is stuffed full of bluebells in spring, and the slugs/
snails never manage to make much of a dent in them, but they're well
established.
