Phytoseiulus persimilis in Sachets

Phytoseiulus persimilis, provided in slow-release sachets, is a low-maintenance solution for preventing spider mite infestations. These sachets ensure a steady release of predatory mites over 2–4 weeks, targeting Two-Spotted Spider Mites, Carmine Red Mites, Pacific Mites, and other spider mite species. Designed for preventative pest management, sachets are perfect for maintaining pest-free environments in gardens, greenhouses, and agricultural crops.

Once deployed, P. persimilis emerges gradually from the sachets, targeting pest mites at all life stages. Each sachet contains a mix of eggs, nymphs, and adult mites, ensuring continuous pest suppression as new predators are released. These mites thrive in temperatures between 68–90°F and humidity above 65%, making them ideal for warm, humid conditions.

Why Choose Sachets?

  • Target Pests: Two-Spotted Spider Mites, Carmine Red Mites, Pacific Mites, and other spider mite species.
  • Preventative Use: Gradual release ensures continuous protection before pest outbreaks occur.
  • Low Maintenance: Simple to hang on plants for effortless, hands-free pest control.
  • Long-Term Control: Perfect for environments with moderate pest pressure and for establishing early prevention.

How They Work

  • Steady Release: Sachets contain all life stages of P. persimilis, providing a controlled release of active mites over 2–4 weeks.
  • Lifecycle Advantage: Eggs hatch into larvae and nymphs, which actively hunt and consume spider mites.
  • Targeted Action: Mites emerge gradually to target pest eggs, nymphs, and adults across plant surfaces.

How to Decide How Many You Need

  • Standard Application: Hang 1 sachet every 3–6 feet, refreshing every 2–4 weeks.
  • High-Risk Areas: Use 1 sachet per plant in environments with high pest pressure.

Pro Tips for Success

  • Deploy Early: Introduce sachets at the start of the growing season to establish predator populations before pests appear.
  • Optimize Conditions: Maintain temperatures of 68–90°F and humidity above 65% for best results.
  • Avoid Pesticides: Ensure no pesticide residues are present to protect beneficial mites.

Storage and Shipping

  • Storage: For best results, hang sachets immediately upon arrival. If necessary, store at 45–55°F for no more than 24 hours.
  • Shipping: Sachets are shipped overnight to ensure live delivery and viability of the predators.
