Neoseiulus californicus Prevention Sachets

Low Effort. High Coverage. Built for Prevention.
Neoseiulus californicus Sachets

When heat spikes, humidity dips, and pests still show up, Neoseiulus californicus doesn’t flinch. These slow-release sachets are packed with a blend of eggs, nymphs, and adults, offering long-term prevention of spider mites, broad mites, red mites, rust mites, and more.

With a comfort zone from 50–105°F and 40–80% humidity, N. californicus thrives where others tap out. If your setup runs hot, dry, or just plain unpredictable, this is your mite.

Why Choose N. californicus Over Andersoni or Persimilis?

Compared to Phytoseiulus persimilis:

  • Persimilis is a spider mite specialist—great for fast knockdowns, but only works in high humidity (60%+) and warmer temps.

  • Californicus is slower but much more durable, surviving low humidity, cool nights, and early-stage infestations.

  • Use Californicus before you see webbing—use Persimilis when you already do.

Compared to Amblyseius andersoni:

  • Andersoni prefers cooler, more stable conditions and won’t tolerate dry heat as well.

  • Californicus keeps working through temperature swings, low RH, and variable lighting—especially in greenhouses and summer setups.

  • Andersoni is a generalist but performs best as a broad-mite/early spider mite suppressant in cool-to-temperate climates.
    Californicus wins when your grow is less predictable or year-round.

Best For:

  • Preventing mite flare-ups before they escalate

  • Mixed mite pressure (spider, broad, rust, red)

  • Indoor, outdoor, or greenhouse setups with fluctuating temps and humidity

  • Growers who want a hands-off solution with a wide operating range

Why Sachets?

  • No rush, no crash. Mites release slowly for ongoing coverage.

  • Low-maintenance. Hang once—done.

  • Self-sustaining. Eggs, nymphs, adults—all stages included.

  • Tolerant. Built for real-world growing conditions, not lab-controlled perfection.

How They Work

  • Mites emerge from the sachet over 2–4 weeks, ready to hunt.

  • They target eggs, nymphs, and adult pest mites before populations spike.

  • Works best as a preventative layer 

How Many to Use

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

  • Elevated pressure: Pair with bottles for a faster knockdown

  • Stacking strategy: Combine with Swirskii or Persimilis when dealing with both thrips and spider mites, or advanced infestations

Pro Tips

  • Keep sachets dry—avoid overhead watering

  • Don’t mix with pesticides or residual sprays

  • Consider booster sachets every 3-4 weeks during heavy pest seasons

Safe For:

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

Fast, easy and educational

Great website, that really helps streamline the ordering process for someone who isn't very knowledgeable with predatory beneficial. Order came, I followed directions, and the mites are active and doing their job well. I was able to see them emerging just 2 or 3 days after I placed them. Would definately recommend, and I will be returning with more business.

I don't know there must have been something wrong with the sachets I received

I don't know there must have been something wrong with the sachets I received. There was no effect.

Thanks for your review — and we're sorry to hear the sachets didn’t seem to have an effect. These particular sachets are designed for prevention, not active treatment. That means they’re best used before a pest population takes hold, rather than in response to an existing infestation.

If you were dealing with visible pests, a bottle release (which contains adult mites ready to hunt) would likely be the better option. We'd love to help troubleshoot and recommend the right solution for your setup — feel free to reach out to us directly anytime.

I received these cute little insects, and they were very lively upon arrival. I hung the bag on my rose bushes, and after a couple of days, I noticed that my roses looked much healthier. I wouldn't say it completely eliminated the mites, but it's definitely much better than before — the roses have even started growing new leaves!

The predatory mite sachets are great but I need to change my subscription and my account shoes no orders and no subscriptions. I just received my order but it looks like another order is coming in a few days which is too soon. I have to way to change it because this is the holiday weekend
