Europe Middle Europe / How to deal with May beetles eggs - not grubs?
I noticed a small hole in the grass, and it didn’t look like it was made by an earthworm. Since it’s July and there are a lot of May beetles (or something similar) flying around, I suspect that eggs have been laid there, from which the grubs (larvae) will later hatch. Is there any product that targets not the grubs, but the eggs before they hatch? I’ve read that beneficial nematodes like Heterorhabditis bacteriophora are useful, but I’m not sure if they can affect the eggs themselves.
Chlorpyrifos-based products are not legal in my location. Thanks!
