Prepare a steel container such as a hibachi, with charcoal and paper to create smoke. Tie or tape a knife securely onto a broomstick. Put on very heavy full-length clothing, gloves, and a wide-brim bamboo hat like the street cleaners wear. Cover the hat and your face and neck with cheese cloth, so the wide hat brim keeps the fabric well away from your skin.
Thus armed, go smoke 'em, then cut it down. Bag it, seal it, and dump it in the wild like Sandman said, while wearing the protective garb.
