CATTLE LICE AXD HOW TO ERADICATE THEM. 9 



Greases and liquids. This group consists mostly of homemade 

 remedies, which are fairly effective and practicable in cases where 

 a farmer has only a few animals to treat and gives the matter his 

 personal attention. While hand treatment is more or less of a make- 

 shift even under the best conditions, it is, nevertheless, sometimes 

 necessarily adopted. The following remedies have proved effective 

 when applied by hand and the treatment repeated, if necessary, in 

 about 16 days: (1) Cottonseed oil and kerosene, equal parts: (2) 

 kerosene and lard mixed in the proportion of \ pint kerosene to 1 

 pound of lard: (3) crude petroleum: (4) any of the dips recom-

The first three reme-

 use during mild 

 weather, but if animals 

 are to be treated dur- 

 ing very warm or very 

 cold weather it is ad- 

 visable to use some of 

 the dips instead of 

 the oils, as the latter 

 are liable to cause in-

 treated cattle are 

 moved rapidly, ex- 

 posed to bright sun- 

 shine, or become 

 chilled. 



These remedies may

over the surface of the head and body, including the inner surface 

 of the ears, care being taken to see that there is no excess quantity 

 at any point. When a dip is used for hand treatment it should be 

 applied liberally after proper dilution over every portion of the body 

 surface including the inner surfaces of the ears and between the 

 thighs. 



SPRAYING. 



On farms where the number of animals is not large enough to 



justify the owner in providing a dipping vat. a spray pump may be 



used to advantage. Where an orchard spraying outfit is available 



it may be utilized for spraying animals. A small spray pump (fig.
