Pirate Bugs

Pirate bugs are tiny predators that can inflict a painful bite.

But, before you try evicting pirate bigs from the garden, it is important to know that pirate bugs are your best defense against thrips.

Pirate bug identification & lifecycle

Pirate bugs are actually called ‘minute pirate bugs’ because of their small size. Adults may only reach 1/5” in length and many varieties feature black and white  patterns. Minute pirate bugs have a triangle-shaped head with relatively long antenna. Pirate bug eggs are laid within plant tissue, providing protection. Within 3 weeks, an egg can metamorphosis into an adult. Pirate bugs can be purchased commercially for release.
