Novel Gas Gun Is Death On Flies
SOMETHING of a crack shot is Dr. J. F. McClendon, of the University of Minnesota, who will not permit flies in his classroom or laboratory.
His air gun is loaded with pyrethrum concentrate, which is four times as strong as ordinary insecticides. When a fly zooms in to put on an annoying aerial exhibition, plop! goes the good doctor’s trusty gun, and there is one less fly to fight against.
