Amblyseius cucumeris Prevention Sachets

Cucumeris for Thrips & Mite Prevention

Thrips don’t show up all at once. They creep in quietly, settle into leaf folds, and multiply long before visible damage appears. Cucumeris Sachets are designed for exactly that moment—before a problem becomes a spiral.

Each sachet contains Amblyseius cucumeris, a proven predatory mite that feeds on thrips larvae and other microscopic pests. The mites reproduce inside the sachet and release gradually over several weeks, providing steady, preventative control where pests actually live.

This is long-game biological control. No sprays. No residue. No disruption to your plants or your space.

What Cucumeris Targets

Cucumeris is most effective against early-stage pests, especially:

Thrips (larval stages)
• Western flower thrips
• Onion thrips
• Greenhouse and ornamental thrips

Also feeds on:
• Broad mites
• Cyclamen mites
• Early spider mite stages

For active or heavy spider mite infestations, pair with a dedicated spider-mite predator.
For aggressive broad or russet mite pressure, use a specialist predator alongside cucumeris.

When to Use Cucumeris Sachets

Cucumeris works best when pests are expected, just beginning, or historically recurring.

Recommended for:
• Preventative thrips control
• Early detection scenarios
• Dense or layered foliage where pests hide
• Plants that are hard to spray evenly
• Growers who want sustained, low-maintenance protection

Active infestation?
Sachets are prevention and support—not a standalone knockdown. For curative control, pair sachets with cucumeris bottles and/or Orius. Apply bottles directly to hotspots while sachets maintain coverage over time.

How It Works

• Mites reproduce inside the sachet
• New predators exit gradually through a pre-made hole
• Multiple generations release over several weeks
• Predators spread through foliage and feed continuously

You won’t see them—and that’s normal. At ~0.5 mm, cucumeris mites are smaller than a grain of sand. If other beneficials in your system are alive, cucumeris is too.

Lifecycle & Feeding Behavior

• Eggs hatch in 2–3 days
• Larvae do not feed
• Nymphs and adults actively hunt
• Adults consume 1–5 prey per day
• Lifespan averages ~20 days
• Females lay 2–3 eggs per day under optimal conditions

This overlapping lifecycle is what allows sachets to provide sustained control instead of a one-time release.

Release Rates & Placement

Preventative:
• 1 sachet per plant
• Replace every 4 weeks

Curative support:
• 1–2 sachets per plant
• Replace every 3 weeks
• Always pair with bottle releases

Placement tips:
• Hang in shaded, sheltered spots
• Avoid direct sun and heat
• Do not open sachets
• Use the cardboard strip for handling
• Tear along perforations when installing

Best Conditions for Performance

• Temperature: Active from 59–77°F
• Optimal range: 68–77°F
• Humidity: 70%+ preferred
• Peak reproduction around 77°F

Compatibility Notes

• Allow oils or soaps to fully dry before release
• Do not combine with other generalist predatory mites
• Compatible with most IPM programs when applied correctly

If you’re unsure about pesticide compatibility, check a current beneficial-insect compatibility chart before application.

Sustainability & IPM Value

Cucumeris sachets replace repeated chemical sprays with living predators that work continuously. They reduce pesticide use, protect beneficial insects, and support long-term ecosystem balance—indoors or out.

What to Expect After Release

• Mites begin dispersing immediately
• Pest pressure declines gradually
• Protection lasts several weeks
• Reapply based on monitoring and plant density

This is prevention done properly—not a panic fix.

Frequently Asked Questions

Can I store sachets for later use?
Short-term refrigeration is acceptable up to the expiration date (typically ~1 month from shipping). Apply as soon as possible for best results. Always allow sachets to reach room temperature before use.

Will I see the mites?
Probably not. Cucumeris mites are microscopic. Their effectiveness shows up as reduced pest pressure—not visible movement.

Are cucumeris sachets safe indoors?
Yes. Safe for people, pets, and plants. Ideal for homes, offices, greenhouses, and interiorscapes.

Do sachets contain adult mites?
Yes. Sachets contain a mix of eggs, juveniles, and adults.

Can I use this on tomatoes?
Yes. Cucumeris performs well on tomatoes and can navigate their leaf structure. For spider mites on tomatoes, pair with a specialist predator.

Does cucumeris eat anything else?
It primarily targets thrips larvae and small mites, with some supplemental feeding depending on conditions.
