Phytoseiulus persimilis in Slow-Release Sachets

Prevent Spider Mites Before They Get Comfortable

If you’ve dealt with spider mites before, you already know: it’s easier to prevent them than to try to clean up the mess. That’s where Phytoseiulus persimilis sachets come in.

Each sachet provides a slow, steady release of predatory mites over 2–4 weeks, built for early-stage control of Two-Spotted Spider Mites, Carmine Red Mites, Pacific Mites, and other spider mite species. Perfect for keeping your grow space protected before populations take off.

These sachets are hands-off, clean to use, and best deployed in warm, humid conditions—think 68–90°F and 65%+ humidity. Each sachet contains a blend of eggs, nymphs, and adults, so predator pressure builds gradually and stays consistent.

Best For:

• Preventing spider mite outbreaks

• Environments with moderate pest pressure

• Indoors, greenhouses, gardens, and covered crops where temps and humidity stay stable

Why Sachets?

• Set it and forget it. Hang once—let them deploy themselves.

• All life stages inside. A rolling release of predators over 2–4 weeks.

• Targeted. P. persimilis only feeds on spider mites—nothing else.

• Mess-free. No sprinkling or mixing required.

How to Use

• Hang 1 sachet every 3–6 feet for general prevention

• For high-risk zones or sensitive crops: 1 sachet per plant

• Refresh sachets every 2–4 weeks during active growing seasons

• Avoid wetting the sachets when watering

Important Note:

These are for prevention or very low pest pressure. If you’re already seeing webbing or widespread mites, start with P. persimilis bottles to knock the population down fast—then use sachets to hold the line.

Safe For Everything But Spider Mites

Completely safe for humans, pets, pollinators, and your plants. These mites are picky—spider mites or nothing.
