Amblyseius andersoni Sachets – Natural Red Spider Mite Control

Prevent spider mite outbreaks before they start – a slow-release, chemical-free solution ideal for houseplants, greenhouses, and conservatories.

Our Amblyseius andersoni Sachets offer safe, long-lasting protection against red spider mites and a variety of other microscopic plant pests. These sachets contain a breeding colony of predatory mites that emerge slowly over 4–6 weeks, providing continuous, preventative protection and stopping infestations before they take hold.

🪴️ What Are Red Spider Mites & Why Prevent Them?

Red spider mites (Tetranychus spp., Panonychus spp.) are tiny sap-feeding pests that thrive in warm, dry environments. They damage plants by feeding on the undersides of leaves, causing yellow speckling, leaf curling, and eventual leaf drop. They are hard to eliminate once established, which is why prevention is key.

✅ How Amblyseius andersoni Work

Amblyseius andersoni mites are widely used in commercial horticulture and are now available for home growers. They are natural predators of:

Red spider mites (Tetranychus & Panonychus species)
Rust mites, Fuchsia gall mites, Pear blister mites, Boxus mites
Thrips and other soft-bodied pests

These mites:

Feed on pest eggs, larvae, and adults
Survive in temperatures from 6°C to 40°C, ideal for early-season use
Tolerate lower humidity better than other predator mites
Feed on pollen and spores when pest levels are low
Can be used indoors all year round or outdoors from late February

🪴 Best for Prevention or Low-Level Infestations

Amblyseius andersoni is primarily used to prevent spider mite infestations or as an early-season control rather than a treatment for heavy infestations. They are especially useful as mites come out of hibernation in early spring.

If you’re dealing with an existing, large infestation, we recommend using Phytoseiulus persimilis first to knock down numbers, then following up with A. andersoni sachets to maintain control.

🪴 Why Choose Amblyseius andersoni Sachets?

How should I apply these sachets to my houseplants for effective spider mite prevention?: Simply hang one sachet per plant from the foliage or insert it into the soil. For larger plants or those under heavier pest pressure, multiple sachets may be required. Replace every 4–6 weeks to ensure continuous protection.
Are these sachets safe to use around children and pets?: Yes, the sachets are completely safe for use around people, pets, pollinators, and beneficial insects. They provide a non-toxic, sustainable method of pest control without the need for chemical sprays.
Can I store the sachets for later use if I don’t need them all at once?: No, the sachets should be used immediately upon arrival as they are not suitable for storage. This ensures the predatory mites are active and effective for optimal pest control.

I did not expect the items in my order to be so stunning and utterly joyous! The moss just sprang into verdant glory as soon as I unshackled it from its wax paper and unleashed it in its prepared spot in the miniature Lord of the Rings mood garden 🤪 As I said to the postie, forget snow to eskimos, we are shipping moss to Argyll! Lovely wee selection. The moss pole with cup is brilliantly designed and will make my monstera much happier in a room heated with a log burner and near a radiator. She is already very tolerant and happy but this will hopefully set her up for winter. A daily drench of warmed rainwater on that pole will recreate Amazonia for a plant that in my experience loves heat as long as humidity is good and I’m confident she will take over the world. Please never stop doing extensions!
