I keep mine in my garage in a brand new aluminum trash can from Lowe's. That keeps out any type of rodents.
To prevent bugs, I weigh out and package my 2-Row Pale to 8# bags (for my Haus Ale) and then I put them in the metal can in the garage and put the lid on. This should keep the bugs out plus it's pre-measured for my next batch of beer
I love my FoodSaver. Here's the contents of a 55# bag of Pale.
