Pirate Bugs:
Greedy Little Pirates With a Purpose

Mainly for use against Thrips, Aphids, and Mites.
The newest Thrips control, Pirate Bugs (Orius insidiosis) also eat Spider Mites, insect eggs, aphids, and small caterpillars. Shipped as nymphs near hatching or adults ready to use (no choice).

Application: Use 100-2000 Pirate Bugs per acre, depending on rate of infestation. Although somewhat expensive, they’re good for infestations when other controls alone aren’t adequate.
