Predatory mites can do a lot against spider mites, fungus gnats and the like. We show where you can buy predatory mites and how to use them.

Beneficial insects have become indispensable in biological plant protection and can help to combat many pests. This is how predatory mites (Gamasina) is often and willingly used to get at various pests.

There are many different families of predatory mites, all belonging to the order mesotigmata belong. Predatory mites, as their name suggests, are predatory and eat other insects.

Predatory mites: profile and properties

Predatory mites are used for targeted pest control in horticulture, but they are also used in fruit production and in vineyards. They can be up to 0.6 millimeters in size and have oval bodies with a smooth surface. The adult animals have four pairs of legs, the coloring of the mites mostly depends on the food they have eaten - red coloring is rather rare.

The development of the predatory mites takes place via the larvae and nymph stage to the adult predatory mites. A female can lay 50 to 100 eggs, which are whitish in color and translucent. The small pests have scissor-shaped mouthparts called chelicerae, which they use to injure and then suck their prey.

The predatory mites are considered to be protective predators, which means that they settle in a stand, so they appear there for a long time, and keep a pest population in check. In contrast, there are the scavenging predators, which can devour pests in large numbers but do not become established in populations. For example, a colonization density of just 0.5 to 1 predatory mite per leaf can keep a spider mite population below the damage threshold.

Each of the predatory mites has its own special prey, which you can easily fight with the beneficial insects. In the case of a severe infestation, it often makes sense to combine several species of predatory mites in order to successfully combat them.

Buy predatory mites: Recommended sources of supply

Predatory mites are bred specifically for use as beneficial insects and then released into the plant population. Depending on the species, many predatory mites are polyphagous in their diet, i.e. they have a wide range of food - the predatory mites for use in plant protection, on the other hand, are predominantly selective. Predatory mites must be approved as plant protection products in the European Union and may only be placed on the market once the approval process has been completed. Therefore, one can be sure that the predatory mites acquired will be of high quality and effective. You also have the assurance that the predatory mites will not harm other beneficial organisms.

Predatory mites are obtained in a wide variety of ways, either as litter or cultivated on plant leaves. In our Plantura shop you will find Predatory mites as sheet goods, which can be used for the targeted control of spider mites.

Use predatory mites as beneficial insects against spider mites and co

Predatory mites are preferably used in protected cultivation - such as in greenhouses or polytunnels. Predatory mites are used to combat the following pests:

• False spider mites (Brevipalpus spec., Tenuipalpus spec.)
• greenhouse whitefly (Trialeurodes vaporariorum), also called whitefly
• Whitefly (Aleyrodoidea)
• salt or swamp flies (Ephydridae)
• spider mites (Tetranychidae), like our Plantura predatory mites against spider mites
• springtails (collembola)
• thrips (Thysanoptera)
• fungus gnats (Sciaridae)

The predatory mites can therefore be used in a variety of ways, and they are particularly popular in protected cultivation.

Tip: If you don't want to use beneficial insects, you can also use a biological pesticide like ours Plantura Organic Pest Free Neem To fall back on. The 100% herbal active ingredient is effective against common pests such as whiteflies and the like.

Are predatory mites dangerous for dogs or cats?

While there are predatory mites that attack dogs or cats, we don't have to worry about the predatory mites that we use in the garden or in the greenhouse. The little animals feed on the pests on the plants and are therefore not a danger to pets. The predatory mites that attack our dogs and cats are the so-called fur mites (Cheyletiellae).
