yeah, that or aphids. you see trails? all that moist foliage around is lovely for those little bastards.
if it's snails, take a strip of copper tape and put it around the rim of your pot and they won't crawl over it. if that doesn't work, they have this really cheap shit that is made of some phosphate that they eat and then die .. but it's not bad for plants, soil, or other animals. I remembered now - sluggo.
