SURE DEATH TO COCKROACH

Commercial Sodium Fluoride Recommended as Effective In Warfare Against Common Household Pest. The Bulletin of the Chicago School of Sanitary Instruction has been dealing with domestic pests, the latest Issue describing a simple and effective way of ridding premises of these un- . pleasant arthropeds. Commercial .sodium fluoride mixed in' equal parts with flour is dusted over places frequented by the insects or applied with a dustgun or powder blower. j . . The immediate effect will be noticed that the insects will come out of their hiding places, and after rushing about in a frantic manner for a time* become paralyzed and soon die. The dead or paralyzed cockroaches may then be swept up and burned. As a rule premises can be ridden of roaches by this method in 24 to 48 hour®. The same mixture Is said to kill caterpillars when fed on foliage that shas been dusted with it. The fluorides should tee used, however, with care and the inhalation of the dust should, of course, be avoided, as these salts have an injurious action on the human subject. Their use as preservatives in food is*legally prohibited in the United States.
