I used root riot cubes. I noticed the worms inside several seeds once the seedlings popped out of the dirt and while the seed shell was still attached to the plant. All the seedlings look healthy and r 1"- 2 1/2" tall. Thr 3 days old. One didn't grow out of the cube so b4 i threw it out i looked at it and saw several worms. So any ideas on how to treat? I don't want to hurt my new seedlings.
