The fly strip was a standard feature of kitchens in the 1940's and 50's. I remember a fly strip in our kitchen at both Dicksons Corners and St. Marys. The fly trap consisted of a strip of yellow paper about 3 inches wide and possibly 24 inches long that spiralled out of a thin cardboard canister.

far corner of the kitchen armed with a coat, a sweater, or a piece of cloth. One person would open the kitchen door and the rest, waving their coats vigorously in front of them would proceed in unison to the kitchen door hoping to sweep the flies outside. In the second story Curly Wilson is reminiscing about St. Marys in the 1890"s: "Manure, smells and flies go together and one cannot imagine the difference between downtown then and downtown to-day. Privies were also a problem but health officer
s were not as aware of the connection of wastes to diphtheria and typhoid as they should have been. A gradual tightening of regulations forced butcher shops to put on screen doors much to the disgust of the owners who felt such regulations were unnecessary and bureaucratic"The number of flies in our homes has decreased dramatically in the past several decades. Whether this is the result of better storage and protection of food, improved methods of screening in homes, or new insecticides, I am not sure. Whatever the cause, one result has been the disappearance of the fly strip as a feature in family kitchens.
