_The_ HOUSE FLY AND HOW TO SUPPRESS IT
[Illustration: fly]
[Illustration: USDA seal]
The presence of flies is an indication of uncleanliness, insanitary
conditions, and improper disposal of substances in which they breed.
They are not only annoying; they are actually dangerous 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 ridding the house of flies
by the use of screens, fly papers, poisons, and flytraps, it lays
especial emphasis on the explanation of methods of eliminating breeding
places and preventing the breeding of flies.
This bulletin supersedes Farmers' Bulletin 851.
