Description
Spical PLUS Spider Mite Predators contain Neoseiulus californicus (formerly known as Amblyseius californicus), one of the most effective and resilient predatory mites available for biological spider mite control. Unlike many specialist predators, Neoseiulus californicus can survive for extended periods even when prey numbers are low, making it ideal for both preventative releases and active infestations. Widely used in commercial greenhouses, indoor grow rooms, nurseries and ornamental crops, Spical PLUS provides long-lasting protection against spider mites and other damaging mite species.
SPECIAL ORDER • Freshly bred and shipped direct from the UK breeder. Order by Wednesday 9am for Friday delivery to ensure your predators arrive in peak condition.
When spider mites are already present, we strongly recommend combining Spical PLUS with Phytoseiulus persimilis Spider Mite Predators. Whilst Phytoseiulus persimilis is often considered the fastest predator for knocking down active spider mite populations, Neoseiulus californicus is generally the tougher and more adaptable predator, offering superior survival rates across a wider range of environmental conditions. Together they provide one of the most effective biological spider mite control programmes available.
Spider Mite Predators for Long-Term Biological Control
Spical PLUS releases a continuous supply of predatory mites into your crop over several weeks. These predators establish themselves within the growing environment and actively hunt pest mites, helping reduce infestations naturally without the need for chemical pesticides.
- Long-lasting controlled release system
- Chemical-free spider mite control
- Suitable for preventative and curative applications
- Excellent survival in varying environmental conditions
- Safe for edible crops, ornamentals and houseplants
- Compatible with integrated pest management (IPM) programmes
- Ideal for grow rooms, greenhouses, nurseries and gardens
What Pests Do Spical PLUS Control?
Neoseiulus californicus targets all life stages, including eggs, nymphs and adults, of numerous mite species.
- Two-spotted spider mite (Tetranychus urticae)
- European red mite (Panonychus ulmi)
- Citrus red mite (Panonychus citri)
- Other common greenhouse spider mites
- Flat mites / False spider mites (Tenuipalpidae species)
- Broad mites (Polyphagotarsonemus latus)
- Russet mites (Aculops lycopersici)
For dedicated broad mite and russet mite control, we recommend using a specialist predator such as Anso-Mite.
Why Choose Neoseiulus californicus?
Unlike some specialist predators that require large populations of spider mites to survive, Neoseiulus californicus can persist within the crop even when pest numbers are low. This makes it an excellent preventative biological control agent and a valuable addition to any IPM strategy.
Compared to Phytoseiulus persimilis, Neoseiulus californicus generally tolerates lower humidity levels, higher temperatures and periods of reduced prey availability. This makes it particularly useful for growers seeking long-term spider mite suppression rather than simply reacting to outbreaks.
How Spical PLUS Works
The predatory mites reproduce within the paper release system before gradually dispersing throughout the crop canopy. Once established, they actively seek out prey and consume pest mites by piercing them with specialised mouthparts and feeding on their contents.
- Feeds on eggs, larvae, nymphs and adult mites
- Typically consumes 5-15 prey items per day under ideal conditions
- Provides continuous predator release over several weeks
- Establishes within the crop for ongoing protection
Application Guidelines
- Begin releases preventatively or at the first signs of spider mites
- Hang units within the crop canopy
- Avoid direct sunlight and heating pipes
- Handle carefully using the cardboard hanger
- Do not open the release unit
- Increase application rates for dense crops or severe infestations
- Fast-growing crops may benefit from more frequent releases
Best Working Conditions
| Parameter | Recommendation |
|---|---|
| Temperature | 13°C - 32°C (55°F - 90°F) |
| Humidity | Best above 60% RH |
| Peak Reproduction | Approximately 30°C (86°F) |
Compatibility With Other Beneficial Insects
- Compatible with Phytoseiulus persimilis
- Compatible with Feltiella acarisuga
- Allow oils and soaps to fully dry before release
- Avoid broad-spectrum pesticides where possible
Spical PLUS vs Phytoseiulus persimilis
Many growers ask whether they should choose Spical PLUS or Phytoseiulus persimilis. The answer is often both.
Phytoseiulus persimilis is the more aggressive hunter and is often the fastest option for tackling active spider mite outbreaks.
Neoseiulus californicus is generally the tougher predator. It tolerates a wider range of temperatures and humidity levels, survives longer when prey populations decline, and provides superior long-term preventative protection.
For established infestations, we recommend introducing Phytoseiulus persimilis Spider Mite Predators alongside Spical PLUS to achieve rapid knockdown followed by long-term suppression.
