Description: Hypoaspis miles / Stratiolaelaps scimitus is a soil-dwelling "generalist" predatory mite which feed on many insects and mites. Adults are a tiny (1mm) tan colored predatory mite. These hardy insects and can adapt to a wide variety of conditions except flooding. These mites will survive mild winters but are inactive below 57°. As with most beneficial insects Hypoaspis work best as a preventative control, before pest populations are high. 
It is recommended to apply Hypoaspis before or shortly after planting. To control high infestation of fungus gnats, Hypoaspis can be used with Beneficial Nematodes (Steinernema feltiae- SF)

Hypoaspis are shipped primarily as adults, but will also include all life cycle stages

Hypoaspis should be applied as soon as received. Do not refrigerate. If necessary, containers can be stored on their side @ 50-60°F for up to 2 days.

The complete life cycle takes approx. 20 days. Hypoaspis hatch in 2 to 3 days into young numphs. Each Hypoaspis can consume up to 5 prey per day.

Strategic Considerations:

We do not recommend releasing Hypoaspis to soils that have been treated with lime. Foliar applied sprays will be less harmful to Hypoaspis than soil drenches.
