How to Identify Red Worms
Red worms get their name due to their red color. There are many varieties of red worms, each kind also has a number of similarities. One similarity is their color and another is that they lay one egg every 7 days with each egg having 3 to 4 worms inside. Their ideal temperatures are no hotter than 84 degrees and no colder than 50 degrees. They all live in soil and need moisture and bacteria to stay alive.
