Scanmask® nematodes are what’s known as insect pathogenic nematodes. They do not harm plants or vegetation of any kind and only work on insect pests that spend part of their life-cycle in the soil.

With that said, I do not think that nematodes will work well on grasshopper eggs as the egg cases contain a cork-like protective layer.
