Killing of rats by one means or another has been attempted as far back as 

 history records. The results are usually temporary and nust be repeatea over 

 and over again. Killing has been placed last in the rat control progra;.i for 

 several reasons, jtoong these are the smartness of the rat itself, the laiov.dedge 

 and care required to use poison successfully, the rapid populati^m increase 

 rate ^f rats, and the failure in the past of -chose who have- relied on killing 

 alone as a control measure. This method is more successful toid is least required 

 v;here sanitation and rat proofing measures have been established and maintained,

PRESSURE LOSS IIT SPRAY EOSE AT DIFFERENT RATES OF YWu 



The working pressure at t.ho spray nozzle is much more significant than the 

 pressure at the guage. This is especially true where a large amount of spray 

 material is delivered through a spray hose of small diameter. The follov/ing 

 figures indicate the heavy losses in pressure where siiiall dio/aeter spray hose 

 is used with a pump of large capacity/.
