I have been offered about a dozen bags of leaves that I thought would be good mixed with manure and soil but on opening a couple of them I found ants and lots of tiny (1/4 inch) never seen before, black worm like insects. I have no idea what they are or if they are harmless to my garden. The bagged leaves are from the NW Austin area. When I opened the bags they got busy moving, maybe they are larva I don't know but do I want the bags of leaves?
I should have taken pictures I know :-(
Thank you for any help.
