Slugs come in all sizes, from itty bitty tiny 1/8" all the way up to 6" wonders. If it's slimy, soft, and slippery, it's a slug.

Easy sure fire way to get rid of those buggers. Small bowl of beer at the base of the plant. You'll be surprised by the bugs you find in the bowl in the morning.

Happy gardening ;-D

come in lots of colors too. anywhere from offwhite to dark grey. i know because i can't stand them. that is why i like toads so much. "eat, my children!eat!"
