SeattleRider, I have a wood rack in my attached garage. Its 27' long and holds 16" splits stacked 4+' high. My cats love to sit in the garage and watch the stack. They're great mousers!

I've never noticed a bug issue, mice yes, bugs no.
I live in tick country (lyme disease) and the major carrier of Deer Tick nymphs are field mice. To try to eliminate as many nymphs as possible, I made PVC tubes with permethrin treated cotton balls in them. The theory is that the mice will steal the balls as nesting material, the permethrin will kill the ticks and not harm the mice. I can't say for certain just how effective it is at reducing the tick population, but for the few $ I have invested in it, it can't hurt. This winter, I've been feeding my fireplace with wood from the garage. I found where all the cotton balls from the tubes scattered around my yard have ended up. I guess the mice don't mind the permethrin....

YMMV, do as you see fit, but I've never had a bug problem with my garage storage. Stock it with dry, ready to burn wood, and be prepared to find a mouse or two in the pile some day...
