Aphidius colemani eating larva.


Aphid parasitoids are tiny (2-3 mm), stingless mini-wasps. They help prevent and correct low-level aphid populations. They can work together with other predatory insects to control over 40 aphid species.

How it works
The wasps lay their eggs in the aphids. The eggs hatch and the resulting larvae devour the aphids from within.

General usage
Use as a preventative measure to stop aphid infestations before they begin. Use as a control for light to medium infestations of aphids. A.matricariae will work with most aphid species. For cotton or melon aphids, use A. colemani. For potato aphids, use A. ervi.

Directions for use
For use in greenhouses, fields, interiorscapes, orchards, and gardens, wherever aphid present a potential or existing problem.
