Amblyseius cucumeris Prevention Sachets

How Do You Stop Thrips Before They Start?

You know the pattern: a silvery patch here, a stunted new leaf there—and suddenly your tent or shelf is full of thrips or broad mites. By the time you notice, it’s already spreading.

That’s why you start with cucumeris.

Amblyseius cucumeris Sachets

Biological Prevention for Thrips Larvae, Broad Mites, Cyclamen Mites, and Russet Mites

These slow-release sachets are designed for preventative pest control. Each one contains live Amblyseius cucumeris in all life stages—eggs, juveniles, and adults—that emerge over time and feed on small, soft-bodied pests like:

• Thrips larvae (Frankliniella occidentalis, etc.)

• Broad mites

• Cyclamen mites

• Rust mites

• Russet hemp mites

Once the mites exit the sachet, they actively feed—but do not establish long-term populations in your crop. This is a fixed-release tool, meant to provide coverage for 3–5 weeks before being replaced.

Not for Outbreaks or Adult Thrips

Cucumeris only feed on the larval stage of thrips—not adults—and they’re not fast enough to knock down active infestations on their own.

If you’re seeing adult thrips flying or crawling, or visible broad mite damage, pair with:

• Orius insidiosus for adult thrips

• Swirskii for faster and broader-stage suppression

• Cucumeris bottles for a quick response while sachets ramp up

How They Work

Each sachet contains:

• Live adult Amblyseius cucumeris

• Eggs and juveniles for staggered emergence

• Bran and carrier material to support humidity

After hanging:

1. Mites exit the sachet over 3–5 weeks

2. They disperse across foliage

3. Adults feed on early-stage pests

4. No colony is established—activity ends when the sachet expires

This makes cucumeris sachets ideal for preventative cycles, not long-term colonization.

How to Use

• Do not open the sachet—mites exit naturally

• Hang near foliage, above the watering line

• Keep out of heavy mist zones or direct irrigation

Best Conditions

If conditions are dry or variable, consider using a “Plus” style sachet for improved release consistency (see below).

Choose Your Brand

Both options contain the same mite species and quantities—choose based on environment:

Tip Top Bio Control 

• Reliable for standard grow tents, greenhouses, and shelves

• Excellent for controlled environments with moderate humidity

• Easy integration for home growers and small nurseries

Koppert “Plus” Sachets

• Enhanced for drier or more variable environments

• Improved moisture retention and consistent mite emergence

• Best for larger grow operations or greenhouses with airflow zones

Pro Tips

• Start early. Best results come when pest levels are still undetectable.

• Pair for full lifecycle control. Add Orius or Swirskii to handle adult thrips.

• Avoid spray residues. Even low-toxicity or oil-based products can suppress cucumeris performance.

• Hang high and dry. If a sachet gets soaked, mite release will stall.
