Earwigs rest in the daytime in dark, damp, cool places. So check under pots, edges of growing frames and any other places near affected plants that fit this description. Hand-pick them off and relocate.
A rolled-up newspaper held with an elastic band may create a hiding place for earwigs. It can then be moved and emptied out in the garden, away from your precious plants.
A small deep container stuffed with straw or hay, laid on its side between the affected plants will give a daytime retreat for earwigs. It can be emptied outside or placed into fruit trees to help control fruit aphid attacks.
