hmmmm, the plastic will ‘breathe’, letting in oxygen. Mylar is metal coated - so it has the flexibility of plastic (almost), but not the porousness. That’s why places like Emergency Essentials puts mylar in their plastic buckets - the buckets are just for structural support since they too will let oxygen in.
Yeah - I’ve frozen beans, rice, etc - to kill the bugs and larvae. For 48 hours. Then I’ve heated them at a low temp in the oven to remove the moisture. (170 for 1 hour). This also kills the bugs, I hear. But I’m one to always overdo anything I try! Then the oxygen-depleted environment will also get rid of anything still alive. If I find any bugs, I will be very upset after all those methods ;(
We’re probably eating bugs all the time, in fresh store-bought food...we just don’t know it ;-)
I once got a big sack of Basmati Rice at a bargain; and in a couple of weeks it was full of bugs. Wish I’d known about the freezing idea back then!
