+1 on all the above advice on freezing/killing critters in bulk food stuffs.
+1 on the advice about mylar food storage bags too. Good stuff.
No one mentioned it, so I will. Invest in one of those Tila Food-Saver[tm] vacuum seal units. You can create smaller portion sizes of some things - rice, beans, flour, instant potatoes, etc. which can be stored up to 2 years for dry goods and a year (frozen) for meats & veggies. I recently cooked up a half-salmon that kept for a year in the freezer this way. And it was tasty.
Vacuum sealed foods keep fresh by keeping air out and this also prevents freezer burn.
