@mainegarden: How about an anti-slug dance?  Have you sprinkled a little salt (not too much) around the plants?  One of my neighbors dries eggshells and then grinds them in his coffee grinder.  Luckily, he supplies me with some each year, and I sprinkle it around the base of my plants.

@Kristen: I always dance in my garden :O)   I tried coffee grounds and they turned the leaves yellow so I panicked and got rid of them.  I have not tried the egg shells.  Does that work?  I actually bought copper dish scrubbers and cut them and placed them around my cabbage when they were young (I heard they won't cross copper)....plus I place pots of mint around (for little green worms).  We had a rest from the slugs because it was hot and dry...it rained last night so they are back.  I will try egg shells next year.  Our egg shells go into the compost presently. 

@mainegarden: the dried crushed eggshells help with slugs when they are sprinkled on the surface of the soil...also, they provide calcium for tomatoes - that helps with blossom end rot

@Kristen: I will give it a try.  The slugs don't bother the tomatoes just everything else LOL.
