My Greenhouse is often plagued by spider mites who love aubergines and courgettes as do I and our family. We garden organically so for us biological controls are the way forward. We have shopped with Harrods in the past and they have always been reliable and professional. Thank You Harrod Horticulture.
Amblyseius (Neoseiulus) andersoni [OUTDOOR] predator sachets work excellently for me on Frankincense plants (genus Boswellia) as a preventative against the dreaded pest Red Spider Mite (RSM). Sachets are fairly easy to hang amongst leaves by draping the twin-sachet over a sturdy stem (no integral hook), and the fast-moving predator mites are clearly visible emerging gradually from within (where they are kept nourished by bran mites so that predators keep emerging for several WEEKS!). Mites seem slightly MORE numerous than with the INDOOR sachets (see separate review), but I tend to use both together for maximum protection. Also useful for mopping-up operations after using Phytoseiulus persimilis predators to tackle a serious outbreak: Amblyseius predators are long-lived and actively seek out any residual RSM.
Amblyseius (Neoseiulus) californicus predator sachets work excellently for me on Frankincense plants (genus Boswellia) as a preventative against the dreaded pest Red Spider Mite (RSM), Tetranychus, even under hot dry conditions (30degC, 30%RH). Sachets are very easy to hang amongst foliage using the integral hook, and the fast-moving predator mites are clearly visible emerging gradually from within (where they are kept nourished by bran mites so that predators keep emerging for several WEEKS!).

Using Spider Mite Killer Sachets
The Spider mite killer sachets contain the predator; Amblyseius sp. This tiny predator feeds on spider mite eggs, nymphs and adults. It will also feed on other mites and thrip larvae. These predators can be applied to plants much earlier than the traditional predator; Phytoseiulus persimlis. This is because it can survive in conditions of lower temperatures and humidity. It also feeds on a variety of food sources.
The sachets have a small hole punched in them that releases the predators over 1-14 days. Hang the sachets on plants like cucumbers, aubergines, tomatoes or ornamental plants. Distribute the sachets evenly amongst plants, for large plants with spider mite ensure that at least one sachet per plant is applied. Each sachet contains approx 250 predators.
Appearance and Lifecycle
The two spotted spider mite is also known as red spider mite or the glasshouse spider mite. This is the most common and damaging species found on greenhouse grown plants. It can also be found on soft fruit and ornamentals outdoors. There is also a species that attacks top fruit and orchard grown fruit. Spider mites need temperatures of 12.c or more to be active. The rate of population growth increases as temperatures rise. Spider mites develop more quickly in hot and dry conditions and their development is slowed down in humid conditions.
During summer conditions in a greenhouse, spider mite populations can develop extremely quickly e.g. at 25.c with relative humidity at 55-85%, the life cycle of spider mites can go from egg to egg in less than 10 days. Two spotted mites go through five developmental stages from egg to adult. They are round in shape and are about 0.14mm in diameter. Two spotted spider mites are clear coloured at first, once they start feeding they turn green with two darks spots forming on their body. They are only red in colour when they are going into or coming out of hibernation. This is triggered by shorter day lengths and lower temperatures. During hibernation the spider mites do not feed. Spider mites generally go into hibernation in the autumn and come out of it in the spring. Female spider mites can lay about 100-150 eggs each depending on the type of plant they are feeding on.
Symptoms and Damage
Spider mites feed on plant tissue and plant sap. This starts as fine speckling on plant leaves, normally on the underside of leaves at first. Eventually leaves go yellow and die. Spider mites also produce webbing when their population level rise and this can cover plants. Spider mites use this webbing to move from plant to plant. They also move from leaf to leaf if plants are touching. Spider mites can totally destroy crops of cucumbers, aubergines and tomatoes if not treated. They are also a threat to ornamentals and soft fruit.
Natural Choice Treatments
Early identification and treatment of spider mites is important. Start checking any overwintering plants in greenhouses early in the year especially when day lengths start to increase. There are safe sprays such as Savona for controlling spider mites early on or for treating hot spots later in the season. Biological control can be achieved using tiny predators of spider mites. Amblyseius sp. in spider mite killer sachets for early treatments and Phytoseiulus persimilis in spider mite killer bottles for curative treatments in the summer.
