Stratiolaelaps scimitus (Hypoaspis miles) – Beneficial Predatory Mites

Predatory Soil Mites for Fungus Gnat and Thrips Management

Stratiolaelaps scimitus, commonly sold as Hypoaspis miles, is a live beneficial predatory mite used to help manage fungus gnat larvae and soil-dwelling thrips stages. Applied directly to soil or growing media, these mites support biological pest management in greenhouses, indoor gardens, and nurseries.

They live and feed in the upper layer of growing media, targeting pests where they develop. Introduce them early as part of an Integrated Pest Management (IPM) program, before pest populations become difficult to manage.

Target Pests

• Fungus gnat larvae: Predatory mites feed on immature fungus gnats in the growing media.
• Soil-dwelling thrips stages: They help manage thrips that enter the growing media to pupate, including Western flower thrips.

These mites work at and below the soil surface. For thrips management, combine them with compatible controls that address pests on foliage and flowers.

Application and Growing Conditions

Distribute the mites and their carrier across the soil or growing-media surface. Keep the media appropriately moist; dry conditions can limit their establishment. Check pesticide compatibility before incorporating them into an existing treatment program.

Follow the application instructions supplied with your shipment. Release quantities and timing should suit the crop, growing conditions, and pest pressure.
