Found these insects all over my cauliflowers hiding under the covers I'm using to blanch the heads.
I suspect it's an earwig. Solutions for control?
And yes, I have a bad case of pieris rapae ... bought some bt today.

Earwig it is! The most important way to control ear wigs is to get rid of the 'housing' the cover they like the most. Rocks, old lumber, compost piles that don't get turned. I don't think they will bother the heads of your cauliflower, they love the juicy leaves.
I would clean up the organic debris around your garden. Earwigs will 'wig' out with no 'home' to run to and might possibly eat the cauliflower heads. I'd still clean up, get your heads harvested and eat them or preserve them.
Next year, plant your brassicas (broccoli, kale, cauliflower...) in a bed that has not had this family grown in it for at least 2 years. Clean up or move compost piles, rocks, old lumber, old construction debris, piles of leaves get them away from your vegetable garden. Remove their homes and protection you will get rid of earwigs.
I have to ask, what is that fibrous piece on the left side of this picture? Is that a coco mat? This is what those earwigs are loving. Remove that for sure, put in a plastic bag to dispose of. Probably full of earwig eggs.
Earwigs are easy to control. You do not need to ever use pesticide as they are not a big problem. Pesticide use would be worse. Clean up the debris, remove rocks and lumber and plastic they love to live under...next year you should have very few if any.
