I kinda like the firecracker idea, to see if they abandon ship, and maybe find where they are coming from. If you put them in a 5-gallon bucket they won't fly around and it even makes them louder imho. Just keep the windows down, but I doubt that they would do anything except make your VX smell like Fireworks (probobly better than it does now) and I love the smell of fireworks.
