It may seem counterintuitive, but I actually like to find pests and bugs in our vegetables, at least these are signs that pesticides likely haven't been used for many weeks leading up to the harvest.
I can relate. I've seen a lot of people going for the "perfect" leaves when buying leafy vegetables. For us who know how pesticides are sometimes being drenched to vegetables for a high yield, we prefer those that have those yummy protein-rich worms. It is an indication that it pesticide free. 😊
The cliff makes me a bit worried. Maybe you should see of the possibility of reinforcing that with stone wall.
