I don't know if your Earwigs are the same as our pest ones but this is worth a try.
Get a shallow dish like a soup bowls and about 1/4 fill with some cheap vegetable oil. Put the bowl out where you know the Earwigs will be and put a stick or small branch from the ground to dish edge. Ours love the oil and climb the stick to get the oil and fall in and drown. The cost is minimal and of course the oil is harmless to pets (or kids).
We have a native earwig that doesn't cause much trouble but these European Earwigs just wreck plants in one night.
