Minute Pirate Bugs, is a general predator of a diversity of insect pests (list below). Release indoors or out. Adults lay their eggs within available plant tissue and can have multiple reproduction events per growing season.  This means they can build up a presence in your garden provided you and your neighbors are not spraying pesticides.
Be sure to leave suitable habitat for them to overwinter as they will establish in most locations quite well.
