UNCO Industries has been in worm farming for over 45 years, beginning as a small redworm bait operation in an old dairy barn. As demand grew, the company expanded and invested in controlled, scalable production. In 1983 it established a climate-controlled facility, and in 2011 moved to a much larger site in Union Grove, Wisconsin to support continued growth.
