nrilE PRESENCE of flies is an indication of un- 

 cleanliness, insanitary conditions, and im- 

 proper disposal of substances in which they breed. 

 They are not only annoying; they are actually dan- 

 gerous to health, because they may carry disease 

 germs to exposed foods. 



It is therefore important to know where and 

 how they breed, and to apply such knowledge in 

 combating them. This bulletin gives information 

 on this subject. Besides giving directions for rid- 

 ding the house of flies by the use of screens, fly 

 papers, poisons, and flytraps, it lays especial em- 

 phasis on the explanation of methods of eliminat- 

 ing breeding places and preventing the breeding 

 of flies.
