Agriculture traps Fly have ha a distinct place In the control of the house fly and other noxious fly species although the lImitations limitations lim lIm- of ot traps fly must be recognized recognized recognized and other methods of control also practiced The bureau of ot entomology entomology entomology ento ento- United States Department of Agriculture points out that the logical method of fly control Is to prevent multiplication b by proper attention to breeding places places- TIle The two main ways In which flytraps flytraps fly fly- traps are valuable are by catching tues flies that come to clean premises from places and by capturing files flies that have escaped from other means of destruction Nearly all flytraps flytraps fly fly- traps are made on th the same general principle although they may appear quite different The flies files are attracted by bait bult odors or light Into a n cage with a large entrance and an exit too small to be easily found which Is often otten made made- by using a shaped cone passage Two Chief Classes of Flies There are two chief classes of flies files that can be be caught in traps traps those thoSe e that breed In animal matter or become a pest to tp live lI stock and those that breed In vegetable as well as In animal matter The former fonner consist mainly of the so-called so blowflIes blow Including the worm screw-worm fly In the latter group the time house fly is by far tar the most Im Im- im- im It Is attracted to almost any I moist material especially that having an odor The general principle Involved In nearly all traps fly Is modified to fit different conditions as In the window trap which catches the flies as they endeavor to enter or leave lea a n building The garbage can trap and the manure box trap which retains flies files bred from infested manure already In the box Light I 1 is an Important factor In the success of ot all traps for tor flies files have a marked tendency to go toward the light While many commercial traps are ore on the market anyone with a few tools can construct traps at nt a small fraction frac frac- tion of of ot the sale price of ready made ones The conical hoop trap which appears from extensive e tests to be most effective durable easily made and repaired can also be made quite cheaply It consists of a n screen cylinder cylinder der with a hoop barrel-hoop frame contain

about SI 1 If only wire and end tacks are bought the cost should not exceed 80 cents A modification of ot this trap that can be bo made more quickly and with fewer tools Is suggested The tent trap traI Is not considered as effective as the conical type Any good trap bee be Lc used over a manure box which must have haye a hole cut In the top The trap Is fitted closely over oer this hole hole- to catch catchflies catchflies flies files bred In the manure A Trap for the Window A type of ot modified d tent trap may maybe maybe maybe be used In a window It Is adaptable also to barns and buildings where foodstuffs are prepared It Is advised that properly baited traps to catch worm screw-worm flies be used near watering waterIng waterIng water- water Ing places and where cattle congre congre- gate In choosing bait for traps fly It should be remembered that fermentation tion renders the material attractive A mixture of cheap strap black molasses molasses molasses mo mo- lasses and water Is an economical and effective bait balt for the house One part molasses Is mixed with three parts water Sugar-beet Sugar or stock stockA a aA A Good Catch molasses Is fairly attractive e In regions regions regions re re- re- re gions where It Is produced Brown Brown- sugar allowed to ferment is good gooc If mixed in the proportion of one part brown sugar In four parts of water A small amount of vinegar added hastens hastens hastens has has- tens fermentation If honey bees are attracted b by this bait some other kind should be used Milk on dairy farms is the next choice to cane molasses as asa asa asa a cheap and convenient attractant The curd from the milk combined with brown sugar and water Is a very good bait The best bait balt containers are broad and shallow rather than deep Traps must be properly cared for and placed In suitable locations locations' The bait containers must be kept well filled and also frequently washed out Traps should be emptied of dead files flies at least once a week Sticky fly papers and poisoned Lilts L' have their uses In fly control as well as traps and It Is advised that Farmers Farmers' Farmers Farmers' Farmers Farmers' Farm Farm- ers' ers
