SUGGESTIONS FOR FLY CONTROL IN POULTRY ESTABLISHMENTS 



Prepared by the Insects Affecting Man and Animals Research Branch, 



Entomology Research Division 



Flies have always been a problem in poultry establishments. In 

 recent years this problem has been increased by the use of batteries of 

 cages with wire floors. Poultry droppings fall through the wire, and 

 if they are allowed to accumulate for several weeks the thick layers 

 and cones formed may provide favorable breeding material for house flies 

 and other species. Surface water from any source, such as a defective 

 watering system or driving rain, will make most of the manure mass suit- 

 able for fly breeding. The breeding is generally greater on concrete or 

 other impervious floors than on bare ground, because there is no loss of 

 moisture by seepage. It is very difficult to control flies in such 

 places, and thousands may be produced daily. 



Good sanitation is the first step in controlling flies around 

 poultry establishments, just as it is around livestock barns and 

 certain processing plants. Manure should not be allowed to accumulate, 

 but should be disposed of at least twice each week. If this procedure 

 is not practicable, an insecticide must be used. Several materials are 

 effective and they may be applied in different ways. Choose the method 

 that is most suitable for your establishment. Insecticides and methods 

 of preparing and applying them are given in the accompanying table. 

 Some of these insecticides can be purchased ready mixed, but most of 

 them are available as wettable powders or emulsifiable concentrates. 



Dry and Liquid Baits 



Poison baits will control adult house flies in certain types of 

 poultry houses and other livestock shelters. Dry baits should be 

 scattered on a fairly dry, hard surface, so as not to dissolve and 

 become ineffective. They may be applied on floors, window sills, in 

 feed rooms, and in other places where flies rest or search for food. 



Liquid baits may be applied with an ordinary sprinkling can on 

 floors, boards, sacks, or similar surfaces. About half the holes 

 should be plugged so that the bait will spread thinly in strips 4 to 6 

 inches wide.
