I too have read that before...but have read in the forum it does not work. Lisa, in her book states that veggies like pumpkin, winter, crookneck, zucchini and other sqash as well as cantaloupe and water melon SEEDS are coated with cucurbitacin, which paralyzes worms. From what I read it seems she is indicating a preventative rather than eradication. Going to futher research effectivness of natural methods. My birds get melon and squash at least once a week. They get mint, kale, parsley and such and law clippings. So all that could explain the loose poo. Anyway further learnig is required of me.
