I have saved my zucchini from the voracious earwigs, thanks to the diatomaceous earth that encircles the plant and was reapplied as needed. The problem is the one plant that was eaten by earwigs (see vimeo https://vimeo.com/45146035)
is stunted. Below is a picture of the "movie star" plant next to the plant I put in the ground one week later. Notice the size difference! The insect damage really set this plant behind.
