Cut em up for bait, leave them on the land, bury them for compost. Do anything you want with them unless it is to toss them back. Invasives are bad news.
Whoever it was that was trying to explain how they aren't a problem, how exactly are you an authority on this?
Think about it this way, the ecosystems that exist developed over the course of billions of years of competition. When you take an organism and put it into an alien environment you do one of two things. You either screw that animal because it cannot compete or you give it heaven on earth because it can out compete much of what is already there. The bottom line is you are creating novel ecosystems that have never existed before and regardless of what you think you may know, you really don't know jack about how the native environment is going to respond now ten years from now or a hundred years down the road.
Did you know that according to the Dept. of Agriculture that invasives are the single greatest threat to our native ecosystems. Were you aware that more money is spent on managing them than on any other ecological threat in the country per year?
Think before you speak champ, you'll come off sounding a lot more intelligent.
