Milk rooms should be well screened. If flies elsewhere on the 

 farm are satisfactorily controlled, the space sprays may be the only 

 treatments necessary to kill the flies that occasionally enter milk 

 rooms. •

In Other Farm Buildings 



Because flies also congregate in other farm buildings, such as beef- 

 cattle and calf barns, stables, poultry houses, and hog pens, it is im- 

 portant that you treat these buildings. Spray them with DDT, 

 methoxychlor, chlordane, or lindane in the manner described for their 

 use around the home. 



Large numbers of house flies can be caught in properly built traps 

 set in the right places.
