How do you preserve your grain?

We get weevils and other small insects in the corn. Last year I moved my totes, about 200 Lbs. of corn outdoors in the winter and that seemed to work very well at killing the bugs. But the totes do not have perfectly tight lids and one tote got pretty buggy by summer.

This year I bought 5 gallon buckets with tight lids and now they are on the back deck enjoying freezing temps.

It got down to -2F (-20C) one day last week and below freezing most of the rest. A research paper I read showed that a few weevils can survive down to -25F for a several weeks! I plan to leave the corn outside until at least February.

How do you all preserve your grains?

The pic shows about 170 Lbs. of corn:

For long term use or if i really care about it, it goes in 5 gallon mylar with homemade o2 absorber where the mice can't get it. Buy cheap and stack it deep

For mostly long term use, i got air tight food grade barrels 55gal and i put Calcium Chloride pellets at the top to act as a dessicant.  Periodically you'll have to redehydrate but if you don't open it, it can last years

But mostly i rotate through what i got before its bad and if and when it gets bugs it becomes chicken food.

But i don't grow all my food, so if I'm going to buy from the store anyway, buy and use before its bad and do the mylar for food security.

Other option for very large scale is a grain bin

Flint corn keeps better too

Most of my corn is now flint after a few years of selection. No question in my mind that the flint corn resists bugs better.
