Anso-Mite Plus

Anso-Mite Plus (Amblyseius andersoni) — Cold-Tolerant Predatory Mite Sachets
Anso-Mite Plus sachets contain Amblyseius andersoni, a cold-tolerant predatory mite for controlling thrips, non-webbing spider mites, rust mites, and whitefly eggs and larvae. These sachets provide slow-release, preventative coverage and early-season protection in cooler environments where other predatory mites may be less effective. Anso-Mite Plus is best used preventatively to stop pest populations before they establish. It is chemical-free, IPM-compatible, and safe for use in greenhouses, nurseries, interiorscapes, outdoor landscapes, and indoor crops including ornamentals, fruiting plants, and vegetables.

Anso-Mite Targets:
Young larvae of various thrips species
Eggs and larvae of whitefly
All stages of non-webbing spider mites (e.g., European red mite Panonychus ulmi)
Rust mites

Curative Note: Anso-Mite is not recommended for high-pressure problems with webbing spider mites (e.g., two-spotted spider mite). For dedicated webbing mite control, use Spidex (Phytoseiulus persimilis) or similar specialist predators.

When to Use Anso-Mite Plus
Use preventively or at the first sign of pest activity, especially in cooler environments where other predatory mites may fail. Ideal for early-season applications and crops with low temperatures.

Recommended for:
Preventative coverage to stop thrips, rust mites, and non-webbing spider mites before establishment
Thrips and spider mite suppression in cold-start crops
Plants requiring clean, residue-free pest control
Situations where pests hide in leaf folds or undersides
Growers seeking a reliable preventative solution

How It Works
Mode of Action: Predatory mites pierce prey with sucking mouthparts and extract internal contents.
Behavior: Mites are typically found on lower leaf surfaces near vein junctions.
Visual Effect: Prey is consumed entirely—only the skin remains.

Feeding Behavior:
All mobile stages are predatory.

Feeding Rates
Nymphs and adults feed on thrips larvae, whitefly eggs and larvae, rust mites, and non-webbing spider mites.
Under optimal conditions, adults consume 5–10 pest eggs or larvae per day.
Feeding life stages last approximately 20 days.

Lifecycle of Amblyseius andersoni
Egg Stage
Oblong, transparent white eggs laid on leaf surfaces near prey.
Larval Stage
Non-feeding; short duration.
Nymph Stage
Beige, droplet-shaped; begins feeding immediately.
Adult Stage
~0.5 mm in size; 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 shaded spots, away from direct sun or irrigation.
Hold by hook or clip to avoid damage.
Do not open sachets—exit hole is pre-made.
Repeat releases based on scouting observations.

Best Working Conditions
Temperature: Effective above 57°F; optimal range 68–82°F.
Humidity: Sensitive to RH below 65%.

Compatibility Guidance
Do not combine with other generalist predatory mites such as A. swirskii, A. limonicus, T. montdorensis, or N. cucumeris.
Allow residues from oils or soaps to dry before application.
Check out our compatibility charts before combining with chemical sprays.

Environmental Impact & Sustainability
Anso-Mite Plus supports sustainable growing practices by replacing chemical sprays with natural predators. These sachets reduce pesticide runoff, protect pollinators, and maintain ecological balance across growing environments.

What to Expect
Mites begin emerging within 2–3 days of placement.
Pest populations are controlled as mites consume larvae and eggs.
Results build steadily and persist as mites survive on pollen or alternative prey.
Reapply based on scouting observations to maintain control and prevent resurgence.

Recommended IPM Pairings
Spidex for spider mite control
Horiver Yellow sticky traps for monitoring flying pest movement.

FAQs
Does Anso-Mite Plus contain adults?
Yes—sachets contain a mix of life stages, including adults, nymphs, and eggs.

Can I use Anso-Mite Plus with other predatory mites?
No—do not combine with other generalist mites like A. swirskii, A. limonicus, T. montdorensis, or N. cucumeris.

How soon will I see results?
Feeding begins shortly after emergence. Control builds steadily and continues as mites disperse across plant surfaces.

Can I use Anso-Mite Plus in any plant or growing situation?
Yes—safe for use on all plants and growing environment.

Does Anso-Mite control webbing spider mites?
Not recommended for high-pressure problems with webbing spider mites (e.g., two-spotted spider mite). Use Spidex (Phytoseiulus persimilis) for dedicated webbing mite control.
