Another trick I learned from my grandmother. Before you toss out cucumbers and squash that have pickle worm -- STOP! All you have to do is put them in a little water with ACV for awhile and the worms come right out. Then they are fine to use. My grandmother used to put a big tin bucket of water in the shade and toss all the cukes, etc. into it. I asked her why she did this, and she showed me the worms. If I had thrown away all the cucumbers and squash I had pickle worm in, I'd never have had any to eat.
