Why fight the larvae?
Many people give priority to the control of the adult animals. In the case of pests in particular, however, it is the larvae that cause the real damage to the plant.
- Adult animals usually only live a few days.
- The larvae eat away parts of plants,…
- suck the sugary juice from the leaves
