Louisiana swamp worm starter colony is the contents of my bin, it contains all the necessary microbes, cocoons, or baby worms to get things going. This takes patience. Cocoons should hatch within 30 days. Shipped priority in a 4 ounce container. When your starter colony arrives immediately place the entire contants in your bin and wet down. Place a wet piece of newspaper on the surface and cover with a piece of plastic or wet burlap. Surface feed some worm chow to get them going.
