Here's a better idea... when I was a kid, my brother and I thought it was fun to pick the ticks off our dog and impale them on a thorn bush, watching them slowly wither up and dry out in the sun. This would be a good idea for these guys also. We should impale them rectally and prop them up out in the Iraqi desert sun until they wither up and die.
