The

HOUSE FLY AND HOW

TO SUPPRESS IT

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.

This bulletin supersedes Farmers' Bulletin 851.
