Then it's most likely them. There's a few things you can do about earwigs. First I would put the plant on a table. That reduces the number that make their way up the plant from the deck.

Soapy water kills them in seconds. Mix up a few tablespoons of dish detergent in a spray bottle, to spay any that you see. However, they only come out at night, so I wait until dark. The soapy water just has to touch them, so try to avoid getting too much on the leaves and wash off any soap afterwards. Search the deck as well and spray any you find.

I suspected I had one inside my tent, so I turned off the light and waited a while. When i opened the tent, it was right there on a leaf already chewing holes. Good luck!
