Over the years we have had a number of weevil infestations in our pantry. I finally had the county entomologist share with me that they tend to be in most commercially packed grains and that all you can do is to go through what you buy fast enough to keep from having a full weevil life cycle get out and into your pantry. I have heard of your suggestion to freeze flower and have been told that this only delayed the start of the insect life cycle to when you took it out of the freezer. (The implication was that your freezer couldn’t get cold enough to kill them but only make they go dormant.) I am looking for information about generating CO2 to replace the air in your packing containers and this would either kill them or keep them dormant the entire time you ore storing them. I have seen one description of using a coin size piece of dry-ice inside the mylar bags before final sealing. The dry-ice idea would not be available after the event. There has to be a simple lime-stone and acid in a mason jar with a piece of aquarium tubing????? (Looking for details on this!???)
4. A .22 rifle.  This is an inexpensive go-to firearm that is useful for hunting small game and is very budget friendly when it comes to ammunition.  Because the ammo is so cheap, a .22 is ideal for learning and developing marksmanship skills.  You can always move up to more expensive guns, but the skills you develop with a .22 will easily transfer to larger caliber firearms. I also like the .22 handgun as well.

There’s a really good app called Prep and Pantry. It allows you to create did inventories, including expiration dates. It scans the barcode too so you don’t have to enter it by hand. This helps me know what I have and lets me plan my meals around when food is expiring. I think it’s about $8, but it’s helped me save a lot of money by not throwing food away.

One major upside of freeze-dried food is its convenience. Since all its water content has been removed—via a process that involves exposing food to subzero temperatures, while removing the resulting water vapor with a vacuum—it’s easier than canned goods to transport on the fly. To “cook” Wise Company’s six-grain Apple Cinnamon Cereal, you just boil three and a half cups of water, dump in the powdery contents of the bag (minus the oxygen absorber), and cover the pot for 12 to 15 minutes.
HBCD has been classified as a category 2 for reproductive toxicity.[6] Since August 2010 Hexabromocyclododecanes are included in the EPA‘s List of Chemicals of Concern.[7] On May 2013 the Stockholm Convention on Persistent Organic Pollutants (POPs) decided to include HBCD in the Convention’s Annex A for elimination, with specific exemptions for expanded and extruded polystyrene in buildings needed to give countries time to phase-in safer substitutes. HBCD is listed for elimination, but with a specific exemption for expanded polystyrene (EPS) and extruded polystyrene (XPS) in buildings.

You should have two weeks’ worth of non-perishable, easy-to-prepare survival food in your home — no good prep is complete without it. If you want to skip the DIY labor and just buy something off the shelf, we spent 180+ hours reviewing over $2,000 worth of the most popular products. After testing 11 options from 7 companies, the best choice for most people is the new Emergency Essentials Premier bucket. Three of which cover two people for more than two weeks for $379.
Forgetting to store spices, salt, oil and basic condiments that are needed for your food storage. How will your famous spaghetti sauce taste without Italian seasoning, salt, olive oil and that pinch of sugar? Beans are a great staple to have on hand and can be seasoned in a variety of ways using salt, cumin, garlic powder, onion powder, soy sauce, ground red pepper and more. 
“If you’re using it for emergency survival, the fact is you’re going to buy it once, and hopefully you’re not going to use it,” Shields said. “But it’s there as a safety net for you and your family.” That’s what intrigued me about freeze-dried food: You can wait up to a quarter-century to use it, but in an ideal world, you wouldn’t have to eat it at all.
