So I bought a ton of flour about a year ago, zip-lock bagged it, and set it in the deep freeze becuse I read that will kill of any bugs wanting to breed.

The other night while talking with my BIL, he said he read something about TWO bug birthing stages, and that if you want to insure no bugs hatch in the flour, after the first deep freeze, you need to pull it out, bring it to room temperature, then refreeze again to stop this second birthing of bugs.

Does anyone know if this is true?

Thanks!
