I found a snake in my backyard (DeKay's) and within the week it ate a slug and half of a earthworm I found in my backyard. I live in SC. Anyway, I just read about Red Wiggler worms and looked at a photo of them and it could have been what I already fed him. I went on a digging expedition and dug up about 100 worms which I have in a bin. Most are earthworm looking (redworm looking) and then there are a handful that are lighter in color and much more squiggly than the regular ones. I am wondering if it may be easier to get them from Walmart. I checked with them today and they do carry night crawlers year round.
