Excerpt from Results of Experiments With Miscellaneous Substances Against Bedbugs, Cockroaches, Clothes Moths and Carpet Beetles Upon careful study Of the habits of roaches it has been found that these insects frequently cleanse their legs and antennae. When any dirt or powder comes' in contact with the appendages, these are at Once drawn through the mouth parts of the insects and in this way cleaned. As a result, a certain amount of any powdered substance applied directly to a roach, or through which it may crawl, is thus taken into the mouth. In this way any poison, whether distasteful or not, finds its way into the stomach. Therefore it is not necessary to mix a stomach poison, in powdered form, with an attractive bait, ' since the chances are much greater that the poison will reach the stomach Of the roach through its habit Of cleansing itself than through the eating of the poisoned bait. True contact poisons, as, for example, mineral-oil sprays, kill by coming in contact with the body. This may result (1) through direct application or (2) by coming in contact with the roach after it has been applied.
