I use ammo cans too, and all bait and lure go in back of truck, not in cab. Same with my setting gloves, those stay in back with the check bucket, not in cab.
Ammo cans albeit plastic or metal have a rubber sealed lid that locks down tight. In offseason I even put skunky lure bottles inside a plastic sealed jar and that jar goes in the ammo can with lid locked down. I'm talking Dunlap's hellfire, June's wind Walker, and cavens long distance call. Those are all very strong skunk odor.
Anyway, do your best, keep it out of the cab when possible, and also find some middle ground with the mrs that hey its trapping and this is seasonal only and part of my favorite hobby.
After season is over clean it up and store it away.
FYI you should see all the air fresheners that my wife hangs in cab of my truck during season. Doesnt help one bit but makes her feel better and I get to drive around a truck in winter that smells like inside of bed bath and beyond with a hint of hellfire.
