Purple Loosestrife

Bio-control is the most efficient way of controlling purple loosestrife, an invasive plant of the water’s edge.

The Process
Bio-control involves either catch and release of beetles or catch, rear and release of beetles. Bio-control is a fun project suitable for many from schools to public works professionals. It all must be approved by the DNR.

Loosestrife is effectively controlled but not eliminated. The plants are weakened and the native plants can regain control of the infested area. Three consecutive years of release is recommended.
