Scientific Name: Eisenia Fetida
This is the most commonly used vermicomposting worm in the world. They can tolerate a wide variety of environmental conditions. These are the worms that most people want to make organic worm castings for their gardens.
For fishing purposes, I have found these to be excellent for panfish and trout.
Note that unlike many sellers, I won't advertise red wigglers and send you blue worms instead. That is a very unethical practice that I refuse to participate in.
These worms are sold as bed runs, which means you will get adults, babies, and possibly some cocoons with your order.
