Nice reminder Granny janny about this, I have always managed without it but intend having a go this spring, as I have enough garlic to make some, and enough slugs to warrant it.
3 large cloves, crushed and added to a tablespoon of vegetable oil, leaft overnight then added to a litre/two pints of water and something sticking like liquid soap of any kind (a teaspoon), strain and either water or spray onto leaves and soil. Repeat every few days and daily if raining.
I shall try it for leatherjackets too….
