I took a little of my garden soil inside to put in a potted plant. I noticed some small (1/4 inch long) white worms that look a lot like miniature millipedes. They have seemed to multiply now and I was wondering if any of you pros might know what they are and if they are detrimental. They are white, almost transparent, have many short legs (like a millipede), they are hard-bodied, and curl up like a pillbug when disturbed. Does anyone have a clue?????
