Neoseiulus californicus Prevention Sachets

Targets: Spider Mites (including Two-Spotted), Broad Mites, Russet Mites
For Prevention in Tougher Conditions

If your pest pressure is inconsistent—or your environment tends to run hot, dry, or low on prey—Amblyseius californicus is a highly adaptable option. These sachets offer slow, steady release of one of the most resilient predatory mites available.

Californicus is most effective against:

• Spider mites (Tetranychus urticae, T. cinnabarinus, etc.)

• Broad mites

• Russet mites

• Other small pest mites, especially under lower food pressure

Each sachet contains eggs, juveniles, and adults that exit gradually over 2–4 weeks. While californicus reproduces more slowly than other predatory mites, it’s also less dependent on high prey levels, making it ideal for use in hotter climates, dryer rooms, or when you’re between flare-ups.

Not for Fast Knockdown

Californicus is a slow-and-steady species, not a rapid responder. If you're dealing with a visible spider mite infestation, start with Persimilis bottles, then use californicus sachets to maintain long-term suppression.

Choose Your Brand

Both options contain the same sachet count and are packed fresh in the U.S.:

• Tip Top Bio-Control – The choice sachet for release timing under typical grow tent, greenhouse, and nursery conditions. 

• Koppert – The Plus sachet formulation offers improved emergence stability, particularly in dry or variable environments where other mites struggle to release evenly.

How to Use

• Hang 1 sachet per plant, or every 2–3 feet in dense canopy

• Do not open the sachet—mites exit on their own

• Replace every 2–4 weeks, depending on temperature, plant density, and pest risk

Best Conditions

• Temperature: 68–90°F tolerant, performs well even above 85°F

• Humidity: Performs better than most mites in lower humidity

• Lighting: Suitable for natural or artificial light environments

Pro Tips

• Best for spider mite prevention. Use after initial knockdown or during early pest detection

• Longer-lasting in low-pest setups. Can survive longer without prey

• Avoid pesticide residues. Residual sprays—even organic—can reduce efficacy

• Don’t expect fast visual results. This species works slowly, but steadily

• Safe for pollinators and pets

• No re-entry restrictions

• Fully IPM-compatible
