Neoseiulus californicus in Slow-Release Sachets

Low Effort. High Coverage. Built for Prevention.

When heat spikes, humidity dips, and pests still show up, Neoseiulus californicus doesn’t flinch. These slow-release sachets are loaded with a mix of eggs, nymphs, and adult mites, providing consistent suppression of spider mites, broad mites, red mites, rust mites, and more.

Built for prevention, these sachets deploy steadily over 2–4 weeks, keeping pest populations in check before they gain momentum. With a comfort zone ranging from 50–105°F and 40–80% humidity, N. californicus is one of the most adaptable mites in your toolbox.

Best For:

• Early-stage control of multiple mite species

• Greenhouses, indoor grows, and outdoor beds with fluctuating conditions

• Environments where other predators burn out

Why Sachets?

• No rush, no crash. Mites release gradually over time for ongoing coverage

• Low-maintenance. Hang once—no mixing, spraying, or second guessing

• Self-sustaining. All life stages included for a naturally building population

• Flexible performer. Handles dry heat, humidity swings, and inconsistent setups

How They Work

• Mites emerge from sachets over 2–4 weeks

• Eggs hatch into nymphs and adults that hunt all stages of pest mites

• Works best as a preventative layer before infestations get established

How Many to Use

• Standard prevention: 1 sachet per plant or every 3 feet

• Higher pressure: Pair with bottles of direct-release predators for faster knockdown

Pro Tips

• Use early in your grow cycle to build pressure before pests do

• Avoid overhead watering directly on sachets

• Don’t mix with pesticides—residue will knock them out

• Stack with Swirskii or persimilis if you’re dealing with mixed mite issues

Safe For:

Plants, people, pets, pollinators—anyone not laying spider mite eggs.

Shipping & Storage

• Use immediately, or store at 50–60°F for up to 48 hours
