To have a building overrun with cockroaches is both undesirable and unnecessary. In the household, cockroaches chew leather and book bindings, soil and impart a disagreeable odor to food materials, and they are potential carriers of disease. In restaurants and hotels roaches are apt to discourage patronage. Infested grocery stores may net as distributors of the insects, and the housewife will not take kindly to finding a roach among the edibles delivered to her kitchen.

Under most conditions cockroaches can be entirely eliminated or at least reduced to negligible numbers by any one of the methods described in this circular.
