text: are carnivorous plants harmful to people?   carnivorous plants are harmless, but contrary to beleif, carnivorous plants are not exterminators! unless of course an ant leads its friends to a sarracenia (north american pitcher plant). i grow these wonderfull plants, and the only way you would put a dent in the bug population is if you got into the 50 ranges, but you could never exterminate bugs compleatly!
