Haven't read every reply, so this may be a repeat. Due to torrential rains all winter, we were inundated with slugs this Spring. Unbelievable numbers. I put out shallow jar lids and trays sunk in to soil level with beer, cheap pumpkin flavored beer seemed to work best. They went in the trays by the hundreds at night. No more slug problem. We also were besieged with sow bugs and earwigs. To our happy surprise, they went for the beer too, still getting many sow bugs a night with this method. No hand picking! Hope this helps!
