The Slug Wars of 2010

I think the garden has a (minor) slug problem (holes nibbled in leaves, a few missing edges). So I did the reasonable thing and went and got a six-pack of Simpler Times, sank a few shallow jars/salsa containers between the plants, filled them each with the brew and a pinch of yeast, and patiently waited. But it's morning number two and still no slug carnage! Somewhere the internets said birds might pick the dead slugs out, so you might not see them, but I just went out pre-dawn and still no slugs! Am I doing something wrong? No noticeable increase in slug damage, either, so maybe they're on vacation, but I'm pretty disappointed. (side note: how do Buddhists grow food? I'm down with growing organically, but not killing pests? How does that work?)

I also read in a book that spreading coffee grounds around the base of seedlings (or just on the ground before they sprout) works. I may try this on the strawberries. And N loves it when I collect and store random trash-like things. Tupperware full of used coffee grounds, anyone?
