I don’t know anything about artichokes, let alone earwigs, but according to my Jerry Baker bible, he suggests “setting out sections of dampened, roled-up newspaper in your garden at night. The next morning, they’ll be filled with earwigs. Drown ‘em or crush’em - your choice!”
I’ve used tons of his ideas on just about everything and they’ve never failed me, even when the solution isn’t exactly what I was looking for..........such as this example, in the book this is for ridding your corn of the earwigs.
Chashmere and Aladden were so excited, jumping around like baby lambs, they thought that I was going to give the zucchini to them! They were used to getting zucchini snacks from the garden last year. But these two zuks are for my supper tonight! They settled for store bought carrots.
