I hate these slimy, disgusting things! I've been battling them for a while now. On my outdoor plants... Okay, fine. I can accept critters crawl on them. But in my pots inside my dew terrarium? Now that I cannot live with. So far they haven't done any damage but its time for them to go bye-bye. I've tried some weaker solutions but I need something better safe for a wide range of plants: carnivorous, cactus and succulent. Suggestions?
