Every year I lose a significant number of plants to slugs. I put out slug killer - although I know that I shouldn't - and kill a few slugs every night but many get through anyway. This year my slug killer has not killed a single slug, I have not seen any slugs in my garden, and not one of my plants shows any sign of slug damages. Have I somehow succeeded in chasing them into my neighbour's yard? Are they massing for an attack? Or is anyone else in my area - near UBC - experiencing this non-problem?
