A few days ago I saw a locust standing still in my little vegetable garden. I was really surprised that even though I went close it wouldn't jump away.
After looking closer I figured that it was actually "pumping" eggs into the soil (check this link for more details).
This morning just before watering I found find this pattern of holes, of similar size of the one that the locust left the previous time.
I have a few questions:
Since they are 1 day recent and I guess not really visible, how deep should I dig to make sure all eggs are removed?
How can I make sure that all eggs die, if in the process of digging I miss some? Should I spray the ground with something? And if yes what do you suggest (considering I also grow edible vegetables)?
How can I stop this locust from coming back and laying eggs in my garden? Is there any natural product that will keep it away? If not natural what should I use (again considering I grow edible vegetables)?
