HOW TO DEAL WITH THE 



FLY NUISANCE. 



House flies are now recognized as MOST SERIOUS CARRIERS OF THE 

 GERMS OF CERTAIN DISEASES such as typhoid fever, tuberculosis, infantile 

 diarrhcea, etc. 



They infect themselves in filth and decaying; substances, and by carrying the 

 germs on their legs and bodies they pollute food, especially milk, with the germs 

 of these and other diseases and of decay. 



NO FLY IS FREE FROM GERMS. 



THE BEST WETHOP IS TO PREVENT THEIR BREEDING. 



House Hies breed in decaying or decomposing vegetable and animal matter and 

 excrement. THEY BREED CHIEFLY IN STABLE REFUSE. In cities this 

 should be stored m dark fly-proof chambers or receptacles, and :t should be 

 REGULARLY REMOVED WITHIN SIX DAYS in the summer. Farm-yard 

 manure should be regularly removed within the same time and either spread on the 

 fields or stored at a distance of nut less than a quarter of a mile, the further the 

 better, from a house or dwelling. 



House files breed in such decaying and fermenting matter as kitchen refuse and 

 garbage. Garbage receptacles shoulcTbe kept tightly covered. 



ALL SUCH KfcFUSE SHOULD BE BURNT OR BURIED within a few davs 

 BUT AT ONCE IF POSSIBLE. NO REFUSE SHOULD BE LEFT EXPOSED 

 II it cannot be disposed of at once it should be sprinkled with chloride of lime. 



FLIES IN HOUSES. 



Windows and doors should be properly screened, especially those of the dining 

 room and kitchen. Milk and other food should be screened in the summer by 

 covering it with muslin ; fruit should be covered also. 



Where they are used, especially in public places as "hotels, etc., spittoons should 

 be kept clean, as there is very great danger of fiies carrying the germs of consump- 

 tion from unclean spittoons. 



Flies should not be allowed to have access to the sick room, especially in the 

 case of infectious disease. 



The faces of babies should be carefully screened with muslin. 



TO KILL FLIES IN HOUSES. 



Mix two tablespoonfuls (one ounce) of 40 per cent. Formalin, (a solution which 

 may be obtained from any drug store at about 40 cents per pound bottle) (20 ounce) 

 with one pint (si.xteen ounces) of equal parts of milk and water. This mixture 

 should be exposed in shallow plates, and a piece of bread placed in the middle of 

 each plate will enable the flies to alight and feed. All dead flies should be swept 

 up and burnt The burnmg of pyrethrum in a room, preferably at night, is som.e- 

 times effective ; the flies should be Swept up and burnt, as many are only'stupefied 

 by this substance. 



HOUSE FLIES INDICATE THE PRESENCE OF FILTH IN THE 



NEIGHBOURHOOD OR INSANITARY CONDITIONS.
