Sprkplug - I've seen them do that very thing over at my neighbor's house, too. However, they are apparently very intelligent people and have developed a technique whereby they alter the physical state of their trashellunge so it can no longer reproduce.
From what I can see, they begin by herding their trashellunge into these big black plastic traps and once full, they tie the tops and store them in the back of a pickup that no longer runs.
When the truck bed can no longer hold any more of the plastic traps, they wait until the wind is blowing towards my house and then toss them one by one into a 55 gallong drum and set them on fire!
I do not know all the details of proper temperature or cook time, but I do know the once solid trashullunge undergoes some sort of reaction and is converted mostly to gas.
I don't think they've quite perfected the method though 'cause there always seems to be a number of the critters that are able to escape and blow around their driveway. I'm thinking my neighbors suffer from poor eyesight or something, because they don't ever seem to notice the ones that get away.
