Spical Ulti-Mite Sachets

Spical Ulti-Mite Sachets (Neoseiulus californicus) — Predatory Mite for Spider Mite Control
Spical Ulti-Mite sachets contain Neoseiulus californicus, a proven predatory mite for controlling spider mites & mite species. Ulti-Mite sachets are designed for long-term, preventative coverage, especially useful for situations where humidity and temperature fluctuate. Unlike standard sachets that falter in dry or high-RH conditions, Ulti-Mite sachets maintain consistent predator release across zones. Spical Ulti-Mite is chemical-free and safe for use in any growing environment including greenhouses, nurseries, orchards, flower beds, interiorscapes, outdoor landscapes, indoor plants including houseplants and more.

Key Advantages of the Ulti-Mite Sachet Format

Humidity tolerance: Reliable release in dry or high-RH environments
Extended release window: 4–6 weeks of continuous predator emergence
Compostable packaging: Industrially compostable film reduces plastic waste
Low-maintenance deployment: Hang and monitor

Use For
Spical Ulti-Mite targets all life stages—eggs, nymphs, and adults—of many mite species, including:

Two-spotted spider mite (Tetranychus urticae)
European red mite (Panonychus ulmi)
Citrus red mite (Panonychus citri)
Other common greenhouse and field spider mites

As a Type II predatory mite, Neoseiulus californicus can also feed on:

Tarsonemid mites (e.g., broad mites, Polyphagotarsonemus latus)
Eriophyid mites (e.g., russet mites, Aculops lycopersici)

*For dedicated broad and russet mite control, we recommend Anso-Mite

When to Use Spical Ulti-Mite Sachets
Use wherever spider mites or other mites are expected or present. Effective across all growing environments.

Recommended for:
• Preventative coverage to stop spider mites before establishment
• Early-stage pest presence
• Hotspots requiring sustained biological control over 4–6 weeks
• 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 Spical bulk bottles and/or Spidex for curative control. In the case of an active problem, Ulti-Mite or Plus sachets work in tandem with bottle formulations to provide long-lasting clean up and prevention against population resurgence. 

How It Works
Mode of Action: Mites pierce and consume pest eggs, larvae, and adults using their mouthparts
Behavior: Mites reproduce inside the sachet and disperse gradually over 4–6 weeks, producing multiple consecutive generations
Visual Effect: Pest populations decline as mites establish and feed
Release Duration: 4–6 weeks depending on humidity and conditions
Sachet Type: Ulti-Mite compostable film; reliable in dry or humid conditions

Feeding Rates:
Nymphs and adults feed on eggs, larvae, and adult stages of mite species, preferred target is spider mites
Consumption varies by prey stage and conditions, typically 5-15 items per day under optimal conditions

Lifecycle of Neoseiulus californicus
Egg Stage
• Oblong, transparent white eggs laid on leaf surfaces
• Hatch in 2–3 days under optimal conditions
Larval Stage
• Non-feeding
• Lasts ~.5 - 2 days
Nymphal Stages
• Actively hunts and consumes prey
• Highly mobile and effective in early suppression
• Lasts ~2 - 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:
Hang sachets in sheltered spots, away from direct sun or heat
Hold by cardboard strip to avoid damage
Do not open sachets—exit hole is pre-made
Open shipping box in crop and tear sachets along perforations
For vertical crops, place sachets above and below pest hotspots

Best Working Conditions
Temperature: Active from 55°F to 90°F; optimal range 68–86°F
Humidity: Performs well even below 60% RH
Reproduction Peak: Fastest at 86°F

Environmental Impact & Sustainability
Spical Ulti-Mite sachets combine biological control with eco-conscious packaging. Compostable film reduces plastic waste and aligns with sustainable growing practices. By replacing chemical sprays, Spical helps reduce runoff, protect pollinators, and maintain ecological balance.

What to Expect
Reliable predator emergence for long-term protection
Each Ulti-Mite sachet delivers a steady stream of predatory mites for 4–6 weeks, ensuring continuous suppression of spider mites and related pests. Mites emerge progressively, establishing across plant surfaces and targeting pest eggs and larvae before populations can increase.

Consistent performance in challenging conditions
Ulti-Mite sachets maintain release rates even under dry or high-humidity conditions. Whether in greenhouses, propagation zones, or indoor environments, expect dependable predator activity without interruption.

Low-maintenance, high-impact control
Once hung, sachets require no further handling. Mites disperse naturally, reducing the need for frequent reapplication.

Recommended IPM Pairings
Spidex for aggressive spider mite knockdown
Spical bottles for curative coverage and hotspot targeting
Swirskii sachets for layered thrips and whitefly control

FAQs

Can I store this for later?
Long-term storage, i.e. more than 48 hours, is not recommended. Apply promptly after receipt. Our products are shipped fresh for immediate use to ensure maximum performance. If needed, keep in a cool, dark, dry place for up to 1–2 days; longer holding reduces effectiveness and quality.

Do Spical Ulti-Mite Sachets contain adult mites?
Yes—sachets contain a mix of life stages, including adults, juveniles, and eggs.

Is Spical Ulti-Mite safe for indoor plants?
Yes—completely safe for people, pets, and plants, making it ideal for enclosed environments like homes, offices, and interiorscapes.

How soon will I see results?
Feeding begins immediately after release. In warm, humid conditions, suppression accelerates rapidly—visible pest reduction often begins within 2–3 days. Mites actively hunt and consume pest eggs and larvae, targeting hotspots with high efficiency. For best results, apply during early signs of pressure and monitor pest decline through scouting or sticky traps.

Can I use this on tomatoes?
Spical is not recommended for tomato crops. Tomatoes have natural resistances to certain predators, making it difficult for Spical to maneuver and hunt on the plant. There is no harm to using Spical in any set-up, however Spical's performance in tomatoes is subject to the specific species of tomato and its maturity. For tomatoes we recommend using Thripex sachets to control thrips and Spidex to control spider mites. These predators can navigate mature tomato plants.

What’s the difference between Ulti-Mite and PLUS sachets?
Ulti-Mite sachets are made from compostable film and tolerate humidity and temperature fluctuations. PLUS sachets are made from paper and should only be used in stable environments. Ulti-Mite is the preferred choice in most scenarios.
