parasitic wasps and hoverflies
These insect species keep your greenhouse free from pests. They feed on spider mites, lice, etc. However, they can only be used to combat them at certain times of the year. In addition, you should create optimal conditions so that the animals feel comfortable. For this purpose, plant umbellifers and daisies in the foreground. These plants serve as sources of nectar.
