Show Proper Fly Control Eliminates Disease Proper Equipment and Application Important Many diseases and cases of contamination con-tamination are traceable to flies. Spraying with DDT and other new chemicals presents the first truly effective ef-fective means of controlling flies. LDT is amazingly effective for several weeks. Flies landing on treated surfaces die in a few minutes min-utes from a condition similar to delirium de-lirium tremens. The main steps to a good fly control program are: First: Clean up the breeding places where flies lay their eggs. Second: Spray DDT on all surfaces sur-faces where flies gather. For this work a sprayer developing some pressure is needed. A garden type compressed air or larger sprayer will do the job efficiently. Around the home, spray the doors, windows, the back porch, out buildings, et cetera. On the farm, the ceilings Compressed air sprayer develops devel-ops 40 pounds pressure for barn and livestock spraying. and walls of barns, poultry houses and hog houses should be sprayed. Two or three sprayings a year will provide excellent control. DDT is positive but slow in its action. Dairymen still are using hand sprayers for a quick knockdown knock-down of visiting flies at milking time. The hand sprayers also are convenient conven-ient for spraying again those areas exposed to rain, where DDT may be washed off. The types of sprayers for fly control con-trol include: (1) hand atomizers; (2) hand pump action knapsack, wheelbarrow, and bucket pump sprayers; (3) compressed air usually usual-ly 2 to 4 gallons in size; (4) engine-operated engine-operated sprayers from to 1 H.P. up in size. At least one of each type should be available. |
