T) OTH THE HOUSE FLY AND BLOWFLIES may 

 -*-^ be captured in traps, but the bait to be used will 

 depend on which kind is prevalent, and on the loca- 

 tion of the traps. This bulletin tells how to make 

 the flytraps that have been found most effective, 

 where to put them, and how to bait and care for 

 them. 



Flytrapping, of course, affords only partial relief. 

 The logical method of fly control is to prevent the 

 multiplication of these pests, by proper treatment of 

 their breeding places. The reader is therefore re- 

 ferred to Farmers' Bulletin 1408 for further informa- 

 tion on house-fly control, and to Farmers' Bulletin 

 857 for additional measures to be used against the 

 screw-worm fly and certain other blowflies injurious 

 to livestock.
