What are Spider Mites and how do I identify them?

There are several species of Spider Mite with the most common being the Two Spotted Spider Mite (tetranychus urticae). These mites have an oval body and eight legs. They vary in colour from green, yellow, orange-red and dark brown. The eggs are circular and generally located on the underside of leaves. The damage will be evident with the yellowing of leaves, especially on the underside. Yellow dots will also show on top with the whole leaf eventually turning yellow. Spider Mites can also produce webbing on leaves when the population is high.

What are Amblyseius andersoni mites and how can they help?

This Spider Mite control tube contains the predatory mites; Amblyseius andersoni. The andersoni feed on the Two Spotted Mite/Red Spider Mite (Tetranychus urticaea) and a range of other pests. See them listed below:

  • Two Spotted Mite/Red Spider Mite
  • Broad Mite
  • Cyclamen Mite
  • Carmine Mite
  • Russet Hemp Mite
  • Russet Mite
  • European Mite
  • Whitefly eggs

Where should I use andersoni?

We advise using Amblyseius andersoni against Spider Mite on indoor and outdoor plants. The andersoni also feed on pollen and this means that they can be applied to plants before, or soon after, the Spider Mite is first observed. This can aid earlier control of Spider Mite populations and reduce risk of sustained damage by combating the Spider Mite early in its life cycle.

What conditions do they require?

Amblyseius andersoni are active at temperatures ranging from 6℃ - 40This enables the introduction of these predators in a variety of environments, earlier in the year, and in lower temperature environments than required by Phytoseiulus persimilis predators, for example.

How do I apply these predators from the bottle?

Spider Mite often feed at the top of plants, so ensure the andersoni are released in that area of the plant, or in other evident hot spots of Spider Mite activity.

The andersoni are supplied in shaker bottles, so you can apply the predators by rotating the bottle and gently shaking the contents directly onto the infested leaves of the plants.

Amblyseius andersoni can also be applied using our Dragonfli Distribution Boxes, which will be more effective for larger plants. Distribute the shaker bottle contents into your boxes and hang them on the stems or leaves of your plants. The boxes act as small breeding sites for the predators before they then proceed to exit the boxes and move around the plants.

Repeat applications may be required to maintain andersoni populations, or if the Spider Mite numbers were high when the predators were first applied.

Full instructions are provided on delivery.

Can I store andersoni?

We advise using andersoni straight away upon delivery. This ensures best results as the Mites will be fresh.

Chemical Pesticides

Amblyseius andersoni is a living creature and can be affected by any chemical pesticides used within the previous few weeks. As a general guide, refrain from using Pyrethrum or SB Plant Invigorator 2 days prior to use. Other chemicals insecticides can have long lasting residues that could harm andersoni and other predatory mites for much longer periods. Refrain from using these products or check with Dragonfli for information on the effect of these products on the predatory mites.
