We need to eliminate these vermin when possible.
During WWII, the Gurkhas in the service of the British Army would very quietly slip behind enemy lines and find a snoozing sentry or two, or a small group of enemy soldiers secure in their belief that their guards were doing their jobs. And then they would slit their sleeping enemies throats, sometimes beheading them and rearranging the heads on different bodies when they were in a particularly mischievious mood.
But they would leave one or two having a particularly good deep sleep alive to find his companions upon waking...and to spread the word to others, doing more widespread damage to enemy morale than just the loss of a few sleepy troops. And after a few evenings of such diversions, the Gurkhas could either move on to other areas where the nighttime sentries had not yet learned how the game was played, or could just get a few evenings reast themselves.
I think the same principle will work nicely in this Texas instance as well....
