FLYTRAPS
AND
THEIR OPERATION
BOTH THE HOUSE FLY AND BLOWFLIES maybe captured in traps. The character of thebait used and the location of the traps greatly influencethe kind of flies caught. This bulletin tells howto make the flytraps that have been found mosteffective, where to put them, and how to bait andcare for them.
Flytrapping, of course, affords only partial relief.The logical method of fly control is to prevent themultiplication of these pests by proper disposal ofor treatment of their breeding places. The readeris therefore referred to Farmers' Bulletin 1408 forfurther information on house-fly control, to Farmers'Bulletin 1097 for various methods of combating thestable fly, and to Farmers' Bulletin 857 for additionalmeasures to be used against the screw-worm fly andcertain other blowflies injurious to livestock.
