HOUSEHOLD INSECTS. 
The House Fly and the Clothes Moth. 
It is the intention of this division of the Experiment Station to 
issue circulars of information regarding our household pests—flies, 
fleas, clothes moths, cockroaches, etc. These circulars can be 
obtained free of charge by writing the Entomologist at the Experi- 
ment Station. The present circular is the first of the series. 
The House Fly or ‘‘Typhoid Fly.’’ 
The name “Typhoid Fly” has been proposed for our common 
house fly because, although a large percentage of typhoid comes 
from our water supply, this insect, by carrying germs of typhoid 
and depositing the same on or in food, has been proved to be an 
Riga Ona House Fly or Typhoid Fly, a, adult male: b, proboscis and palp 
of same; ¢. terminal joints of antennae; d, head of female; e, puparium; f, anterior 
spiracle, all much enlarged. After Howard, Bur. Ent., Dept. Agriculture.
