Thrips are plant feeders that feed on leaves, leaving a trail of damaged tissue and fecal matter. They are so small that they can barely be seen by the naked eye. They mature after seven to 10 days and lay 200 to 250 eggs, so the population increases quickly. The larvae feed on leaves.

Onus insidiosus, the minute pirate bug, is a small insect that pierces thrips with its mouth and sucks out their liquids. They reproduce quickly—every 10 to 20 days—and rapidly decimate the adult population. Available from IPM Labs and Nature's Control.
