Thanks a lot for your answers.

Do you know of any organic approach?
I have heard about various biocontrol agents used in the fight against
Melolontha melolontha larvae (like fungi and nematodes).
Wouldn't it be possible to have a similar approach to the specific problem?
Has anyone tried it?

Best regards.
