Spider mites: how to spot, prevent and treat them pest

How do you spot spider mites?

Small pale dots show over the upper side of the leaf, with a generally faded look. In a heavy attack the leaf browns or yellows and the plant dies. When it gets worse, a fine web is visible between the leaves.

How do you prevent spider mites?

Most at risk are the plants that stand in the dry air of a room all year. Mist regularly and raise the air humidity to lessen the trouble. Keep new plants apart from the others for a few weeks.

What works against spider mites?

On sturdy plants wash them off thoroughly with water first. Then potassium soap, which works on contact and has to reach the underside of the leaf.

Check the registration and the label before use.
