The Mis-named Red Wriggler !!
The common name “Red Wriggler” has been associated with another red-coloured worm that isn't from the “Red” (rubellus) family, but is from the “Tiger” family. The Latin name for the Tiger Worm is Eisenia fetida. The worm mis-named “Red Wrigglers” are actually “Red Tigers”, which are a sub-species of the Tiger Worm. Red Tigers are Eisenia fetida andrii. Another common name is Red Brandling Worm. These worms do not “wriggle” as much as the real “Red Wriggler” when exposed to sunlight, and almost appear sluggish in comparison to the True Reds. Also, all Tiger Worms release a ‘fetid' taste and smell as a defense mechanism, and therefore are NOT suitable for fishing! So selling “Red Tigers” as “Red Wrigglers” makes a HUGE difference to fishermen looking for a true “Red Wriggler”, and is somewhat misleading.
Tiger Worms (regular and red) are ideal for composting rich organic waste from the kitchen as they live off a rich source of food,and process large amounts.
