Yes

I wouldn't do it Wen. What I have read in the last year I've been learning this is that when you start putting in starches--bread, rice, oatmeal, etc--you start asking for problems. On top of that, you have sodium and other stuff in those crackers.

I won't say it will kill your worms, but I cannot tell you how many people have passed through this forum and others like it reporting that they have killed all their worms.

I have stuck to fruits, vegetables, egg shells, tea bags, and coffee grounds. (rejecting only lemons). I have never once killed off my worms. I have more than enough fresh scraps as it is without cleaning out the cupboard too. In fact, whatever it is that I do differently, it is so effective that it makes this whole vermicomposting thing seem easy. I'm not judging anyone who has a mass die off for whatever reason. I'm just saying that if you don't go looking for trouble, it's a little less likely to find you.

The problem with starches is putting in too much. I have killed worms by feeding to much starch, but I still will feed starches in small amounts. The worms love them, if you don't overdo them.

I have been dumping cornmeal into a tiny flowthrough covering the top 1/4 inch thick weekly. I still can't get any worms to die. I also agree with the above posters. I think it depends like fruit on if fermentation happens.

Are they salted? If no, I would but them in bit by bit.

From my experience, too much starch causes heat. I don't know how you put in 1/4 inch of corn meal at a time without it heating up.

Me either. It would not heat up. It was a cold winter in my basement for them.
