Are you sure, at least as far as keeping airborne critters away? The real nasty part is when the plane is on the ground, engines running, and it’s not a 787 so it has a bleed air system, and it stinks. As I understand it, this happens because the ventilation system does work the same way as it does in the air, and it’s a bad idea!
