Yeah, that's it exactly backwoods. Thankfully I have no oak beams or anything like that in the house they can migrate to.
As above, it's good for many years if kept dry. Ideally, you would burn it in the order that it becomes "mature", i.e <20% M.C., but, I'm slow learning, "Minimize the number of times you handle your firewood." It all adds up over time.
I have some leftover in the shed most years. (Good planning, IMO) I put it the basement thru summer & burn it first next burn season. I start the next season Burning 4 year old wood Then the rest of winter burning 3-1/2 year old wood It's a good thing, IMO, figure a way to burn it first next burn season
Build one of those mythical negative heat loss fireplaces and burn wood for air conditioning in the Summer.
I would agree about insects, insects turning your wood into dust means that you are not using it to heat your house. I would not continue stacking wood in front of it and never using it to only find out later that insects ate your wood instead of you burning it for heat. You put work into getting that wood so don't risk losing it and not getting to enjoy the heat from burning it.
I get the PPB in maple stacked. Every year. They seem to enjoy fresh stacked maple. They must be gone by Fall because I never have any bugs beyond a spider or two in the house. Besides, most any bugs in wood need the moisture and most homes in Winter that heat with wood are far too dry for their survival. Spiders likely suck what's left out of them and they dry up and blend in with the dust in the vacuum cleaner bag. There's another kind of PBB that is content to chomp down on softwood. The floor joists in my basement were painted with some kind of black tarry substance to either drive them out and/or repel them. Before my time.
