Spidex & Spidex Vital Predatory Mites – Biological Spider Mite Control
Spidex and Spidex Vital contain the beneficial predatory mite Phytoseiulus persimilis, a specialist natural enemy of two-spotted spider mites. These fast-moving predators actively search plant foliage for spider mites, providing targeted biological control as part of an Integrated Pest Management programme.
Available with 2,000, 10,000 or 25,000 predatory mites per bottle, the range provides a choice of pack quantities for different crop sizes and infestation levels. The mites are supplied in a woodchip carrier, ready to distribute onto foliage or into suitable introduction boxes.
Introduce the predators as soon as spider mites are detected. Unlike general-purpose preventative sachets, these bottled products are intended for targeted release where suitable spider mite prey is present.
Key Features & Benefits
- Specialist spider mite predator: Contains live Phytoseiulus persimilis beneficial mites.
- Targets multiple pest stages: The species feeds on spider mite eggs, larvae, nymphs and adults.
- Three pack quantities: Choose 2,000, 10,000 or 25,000 predatory mites.
- Active searching behaviour: Predators move across foliage and spider mite webbing to locate prey.
- Direct crop application: Bottled carrier material can be sprinkled onto leaves or placed in suitable introduction boxes.
- Spidex Vital colour change: Predators in the Vital options change from white to red after feeding on spider mites.
- IPM compatible: Can form part of a coordinated biological pest management programme.
Available Pack Sizes
| Product Option | Predatory Mite Quantity | Bottle Size |
|---|---|---|
| Spidex Vital 2,000 | 2,000 | 100ml |
| Spidex 10,000 | 10,000 | 500ml |
| Spidex Vital 25,000 | 25,000 | 500ml |
Please Note: The millilitre measurement refers to the bottle size, not a liquid treatment volume. The 10,000 and 25,000 options both use a 500ml bottle but contain different quantities of predatory mites.
Targeted Biological Control of Spider Mites
Phytoseiulus persimilis is used to control two-spotted spider mite (Tetranychus urticae) and other suitable Tetranychus species, excluding Tetranychus evansi.
Its ability to move through spider mite webbing helps it reach pest colonies on affected plants. The predators feed on susceptible spider mites rather than relying on a chemical spray to control them.
This is a specialist spider mite treatment, not a general-purpose control for aphids, thrips or every type of plant mite. Correct pest identification is important before ordering.
What Is Different About Spidex Vital?
Spidex and Spidex Vital contain the same predatory mite species, but their production diets differ.
The predators supplied in Spidex Vital are initially white and become red after feeding on spider mites. This colour change can help indicate that the introduced predators have found and consumed their target prey.
Within this listing, the 2,000-mite and 25,000-mite options are Spidex Vital. The 10,000-mite option is standard Spidex.
How to Apply Spidex & Spidex Vital
- Inspect the crop: Confirm spider mite activity and identify affected areas.
- Gently mix the contents: Turn and gently shake the bottle before application to redistribute the predators through the carrier.
- Open as directed: Follow the instructions for the bottle closure supplied.
- Distribute the material: Sprinkle onto leaves or dispense into suitable introduction boxes positioned within the crop.
- Keep the carrier in place: The material should remain at the release location for at least several hours so the predators can disperse.
- Monitor and follow up: Check pest activity regularly and repeat releases according to the recommended programme.
These products are supplied for direct release from a bottle. They are not hanging slow-release sachets and should not be mixed into a spray solution.
Application Rates & Repeat Releases
Koppert gives a general introduction range of 2–50 predatory mites per m² per release, with one or two further introductions at weekly intervals.
The appropriate rate depends on the crop, temperature, humidity and spider mite population. Obtain crop-specific advice before selecting your quantity, particularly for established infestations.
Important: Pack quantity alone does not establish a fixed coverage area. The same bottle may cover different areas depending on the required release rate.
Temperature & Humidity Requirements
Phytoseiulus persimilis performs most effectively between 13°C and 27°C. Koppert advises that it is not effective above 30°C and is sensitive to relative humidity below 70%.
Check that your crop conditions are suitable before introducing the predators. Hot, dry environments can limit performance, and any environmental adjustments must also remain appropriate for the plants being grown.
Using Predatory Mites in an IPM Programme
Spidex and Spidex Vital can be incorporated into an Integrated Pest Management (IPM) programme alongside crop monitoring and compatible biological controls.
Some crop protection products and their residues can affect beneficial mites. Check pesticide compatibility and any required waiting periods before introducing predators or applying further treatments.
Continue monitoring after release rather than assuming a single application will resolve every infestation.
Storage & Handling – Live Beneficial Mites
Apply as soon as possible after delivery. These bottles contain living organisms, and unnecessary storage can reduce their quality.
Where a short delay is unavoidable, Koppert specifies storage for 1–2 days at 8–10°C, keeping the bottle horizontal and in darkness. Follow the handling instructions supplied with your order.
Plan your application before delivery so the predators can be introduced promptly under suitable conditions.
