- Apply the predatory mites on the soil, not on the crop. If you do not have any experience with a specific crop or variety then begin by carrying out a small-scale test. Alternatively, ask your supplier for advice
- For an optimum result we recommend that you cover the soil/pots with a top layer after application and keep this layer moist, for example by installing one or two tricklers. We have excellent experience with Crustell’s Biotop product

Mode of action
Adults and nymphs feed on thrip pupae and other soil insects.
The mites can be seen on the soil and around the base of the plant. Macrocheles is not seen on the plant. The mite reduces infections of thrips and black fungus gnat.
