Vacuum seal EVERYTHNG. Daisy seal-a-meal LOVES GLOCKS! And they love it right back. Ammo in Ammo cans for intermediate storage but with an absorber and vacuum sealed for long term. Invest in long term food storage. I have 6+ months of food that is good for 25 more years.
The fancy food storage really gives me comfort....
If I live long enough for it to expire (which I doubt) I'm going to give it to the local scout troop. lol
