They will get through the bird netting. Get some row cover.

Row cover material is sold in several - approx. 5 or 6 - different weights. It ranges from the lightweight "inset barrier" (which is what you need) down to 20 degree frost protection (which is quite thick).

I agree that bird netting won't prevent cabbage moths laying eggs.

If you have the wrong row cover, just go down to a fabric store and get some wide tulle. It should come as wide as 108" and probably be white but it'll work. Get enough to double it because it's easier to handle that way. You can tape the edges with something like masking tape to keep it from tearing or make your own bias tape and use that if you sew.

Thank you everybody! Dave, I didn't know the row covers came in different weights. Thank you:)

And Shebear, that is a fabulous idea with the tulle! I'm off to Joanne Fabrics today to find some:)

Thanks a bunch everyone!
