Rodents

The article ["The Purpose of Eugenics"] added thoughts about eradicating such a problem. "It is interesting to note that there is no hesitation to interfere with the course of nature when we desire to eliminate or prevent a superfluity of rodents, insects or other pests; but when it comes to the elimination of the immeasurably more dangerous human pest, we blindly adhere to the inconsistent dogmatic doctrine that man has a perfect right to control all nature with the exception of himself." It was the second time that year that Sanger's magazine had published virtually the same phrases declaring lower classes to be more dangerous than rats and bugs. Such denunciations were commonplace in Birth Control Review.
