Blister beetles are also common in alfalfa and clover fields. They are 

 usually associated with grasshopper infestations, particularly those of the previ- 

 ous year. 



Stable flies may become more bothersome to livestock in the near future, 

 since the rains provide necessary moisture for successful survival of the stable 

 fly maggots. The same can be said about house flies. 



For dairy cattle , apply 2.0% ciodrin, 1.0$ DDVP or 0.1% pyrethrin in a 

 mineral oil base. Spray at the rate of 1 to 2 ounces per animal per day or as 

 often as needed. Be sure to spray the undersides and legs. 



For beef cattle , app3.y a 0.5% toxaphene water-diluted spray at 1 to 2 

 quarts per animal every three weeks. Allow 30 days to elapse between treatment 

 and slaughter when using toxaphene. Thorough coverage of the animal is important 

 for effective results. Ciodrin, 2.0% in oil, applied two or three times a week 

 with an automatic sprayer can also be used effectively. 



Caution : Before applying insecticides, read the labels carefully and 

 follow all precautions. This will not only insure personal safety, but will also 

 eliminate insecticide residue hazards.

 pesticides, write to 280 Natural Resources Building, University of Illinois,
