Thripex-Mini (w/stake)

Thripex-Mini Sachets with Sticks (Neoseiulus cucumeris) — Predatory Mite for Thrips and Mite Control
Thripex Sachets with Sticks contain Neoseiulus cucumeris, a proven predatory mite for controlling thrips larvae and several mite species. These sachets are identical to Thripex Plus but include integrated sticks for easy placement in short crops such as stuck cuttings, nursery plants, and propagation trays. Mites reproduce inside the sachet and disperse gradually into the areaover several weeks. Thripex Sachets with Sticks are chemical-free, IPM-compatible, and safe for use in greenhouses, nurseries, orchards, flower beds, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.

Use For
Thripex Sachets with Sticks target young larvae of various thrips species, including:
Western flower thrips (Frankliniella occidentalis)
Onion thrips (Thrips tabaci)
Other greenhouse and ornamental thrips (e.g., Echinothrips americanus, Thrips fuscipennis, Thrips simplex)

As a Type III generalist, Neoseiulus cucumeris can also feed on:
Broad mites (Polyphagotarsonemus latus)
Cyclamen mites (Phytonemus pallidus)
Spider mites

For dedicated spider mite control, we recommend Spical or Spidex
For dedicated broad and russet mite control, we recommend Anso-Mite

When to Use Thripex Sachets with Sticks
Use wherever thrips or small mites are expected or present. Stick design engineered to support propagation rooms and nursery growers.

Recommended for:
Preventative coverage to stop thrips and mites before establishment
Early-stage pest presence
Short crops such as stuck cuttings, nursery plants, and propagation trays
Plants with dense foliage or layered canopy structures where pests hide in leaf folds and undersides
Growers seeking long-term prevention & control

Curative Note:
Pair sachets with Thripex bulk bottles and/or Orius spp. for curative control. In the case of an active problem, sachets work in tandem with bottle formulations to provide long-lasting clean up and prevention against population resurgence. For short crops with an active problem, place sachets close to the hotspot and apply bottles directly at the problem. This dual strategy prevents pest spread and accelerates control.

How It Works
Mode of Action: Mites pierce and consume pest eggs and larvae using their mouthparts
Behavior: Mites reproduce inside the sachet and disperse gradually over several weeks, sachets produce multiple consecutive generations of predatory mites
Visual Effect: Pest populations decline as mites establish and feed
Release Duration: Several weeks depending on humidity and conditions
Sachet Type: Paper-based sachet with integrated stick for vertical placement

Feeding Rates:
Nymphs and adults feed on thrips larvae, mite eggs, and pollen
Nymphs and adults consume 10–15 pest eggs or larvae per day under optimal conditions
Total consumption across lifespan can exceed 150–200 prey items, depending on prey density and environmental conditions
Feeding life stages last approximately 10–18 days

Lifecycle of Neoseiulus cucumeris
Egg Stage
Oblong, transparent white eggs laid on leaf hairs along veins
Hatch in 2–3 days under optimal conditions
Larval Stage
Non-feeding
Lasts 1–2 days
Nymph Stage
Begins feeding on thrips larvae and mites
Highly mobile and effective in early suppression
Nymphal development lasts 4–6 days
Adult Stage
Actively hunts and consumes prey
Lifespan ~20 days
Capable of laying 2–3 eggs per day under optimal conditions

Release Rates & Placement

Placement Tips:

Insert sticks directly into substrate or media near plant base
Position sachets away from direct sunlight or heating pipes
Hold by cardboard strip to avoid damage
Do not open sachets—exit hole is pre-made
Open shipping box near plants and tear sachets along perforations

Best Working Conditions
Temperature: Active from 59°F to 77°F; optimal range 68–77°F
Reproduction Peak: Fastest at 77°F
Humidity: Optimal at 70% RH or higher

Compatibility Guidance
Allow residues from oils or soaps to dry before application
Do not combine with other generalist predatory mites (Amblyseius swirskii, Amblydromalus limonicus, Transeius montdorensis, Amblyseius andersoni)

Environmental Impact & Sustainability
Thripex Sachets with Sticks support sustainable growing practices by replacing chemical sprays with natural predators. Sachets reduce pesticide runoff, protect pollinators, and maintain ecological balance across growing environments.

What to Expect
Thripex Sachets with Sticks release predators consistently after placement
Thrips and pest mites are suppressed as predators feed
Predators disperse through foliage for several weeks
Reapply based on scouting observations to maintain control and prevent resurgence

Recommended IPM Pairings
Horiver Yellow sticky traps for monitoring whitefly and winged thrips
Thripor for increased thrips control during high-pressure problems
Isarid Mycoinsecticide for knockdown in high-pressure zones

FAQs

Does Thripex Sachets with Sticks contain adult mites?
Yes—sachets contain a mix of life stages, including adults, juveniles and eggs.

Is Thripex Sachets with Sticks safe for indoor plants?
Yes—completely safe for people, pets, and plants, making it ideal for use in enclosed environments like homes, offices, herb gardens and interiorscapes.

How soon will I see results?
Feeding starts immediately. Control builds quickly as predators move through affected areas.

Can I use this on tomatoes?
Yes, Thripex-Mini is recommended for tomato crops. Tomatoes have natural resistances to certain predators, making it difficult for some predatory mites to maneuver and hunt on the plant. There is no harm to using Thripex in any set-up & Thripex is able to navigate tomatoes. For spider mite management in tomatoes, we recommend Spidex.

Does Thripex feed on other pests?
Yes—Neoseiulus cucumeris feeds on thrips larvae, broad mites, and other small mites.

What is the difference between Thripex Plus and Thripex Sachets with Sticks?
Both products contain the same predatory mite species and offer identical performance. The only difference is ease of placement:
Thripex Plus: Standard sachets for hanging on stems or branches
Thripex Sachets with Sticks: Sachets with integrated sticks for easy placement in short crops such as stuck cuttings and propagation trays
