Yep - Your going to need a food grade (NEW) 6 gallon plastic bucket with lid, some bleach and water. A mylar bag and a freezer or dry ice, and lastly a vaccum cleaner. OR - Food grade diaetamaceous (DE) earth (I know I FUBARed the spelling on that one)
#1 Clean the bucket with bleach and water, to include the rim. Check carefully for cracks, if you find any start over. Allow bucket to dry
#2 Put mylar bag in the bucket, check for tears - I fill mine with a bleach and water solution and hold looking for leaks. Empty and dry carefully and through.
#3 Put your food in the bag: This is where you have several options. THe most effective is DE. DE is microscopic sea shells that act like razor blades to roaches, weevils, ect. BUT you can eat the stuff all day, just be careful and wear a dust mask as it's bad ju ju if it gets in your lungs. You can just mix the stuff up.
* You can freeze the food for 24 to 36 hours and immediately store in the bucket and seal. (Still in mylar) The vaccum cleaner sucks the air out, and I forgot you'll need an iron and a scrap of wood to iron the open end shut.
* You can go lo-budget if you dont have a bag you can put bay leaves in the bottom of the bucket, add your food untill its about a handswidth from the top. Add about 1 to 2 pounds of dry ice (I buy mine at the supermarket) Place in a towel (Clean) on top of the food and leave the lid cracked. Wait about 20 min, the dry ice turns to CO2 and settles to the bottom of the bucket, Cap the bucket and seal. Check up on the bucket in 2 to 4 hours. IF the bucket seems caved in, crack lightly and repeat.
The CO2 replaces the oxygen in the bucket and if any critters survive they choke on the co2 - free protein!
