We cannot guarantee a 100% pure species of any type composting worms. Our worms are harvested from worm beds that are decades old and may depending of time of year contain several different compost worm species. Not to worry!  Bed run worms are superior because they work all layers of the compost not just the top few inches. Giving you a better compost faster. This also gives an advantage in that as conditions change certain species will multiply as conditions become unfavorable for another keeping you with a constantly healthy composter.  Because they are bed run some orders may have more than one species than another but rest assured their populations will naturally adjust to the needs of your waste. Because of the adaptive nature of worms some varieties reproductive rates change with warmer weather, colder weather, moisture levels, soil content etc.
