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. Anso-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.

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)
Tomato russet mites (Aculops lycopersici) aka "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 or early intervention to stop thrips, rust mites, and non-webbing spider mites
Thrips and spider mite suppression in cold temperatures and early-season plantings

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 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.
Nymphal Stages
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 page before combining with chemical sprays.

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

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.

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.

Why choose beneficial predators?
Beneficial predators provide a sustainable, long-term approach to pest control:

• No resistance issues: Pests cannot develop resistance to natural predators, eliminating the constant cycle of switching chemical products.
• Easy to scale: As plants grow, predator introductions can be increased without overhauling the program, ensuring consistent results and minimal disruptions.
• Cleaner and safer: Replacing chemical sprays reduces pesticide runoff, protects pollinators, and promotes a more natural growing system.
• Superior quality: At Natural Enemies, we are the insectary. Products are held to the highest standards, ensuring vigorous, effective predators that perform reliably in real-world growing conditions.
