You had me googling cricket's diet there , lol .
Yes it looks like slug or catterpiller damage , slugs are our enemy.
They can climb or slimb from one plant to another , as you's are surrounded you might have problem's defeating them . Maybe cut back ajoining plant's .
Copper is a deterrent , it gives them a shock and they wont cross that barrier . Various product's are available or you can make you'r own from tube/pipe etc , it's said that the copper should ne at least an inch in height to work effectivly .
Hope you solve this problem
