Remedies for Lice 333 



pose quite as well. Older fowls should be given 

 an opportunity to take dust baths. This is nature's 

 method and is effectual if the fowls will bathe 

 thoroughly. Many of the heavier fowls, however, 

 do not care to take dust baths frequently, nor to 

 do the work thoroughly when they undertake it; 

 consequently it is frequently necessary to use 

 artificial methods to kill or drive away the lice, 

 when they once become well established on adult 

 fowls. Powdered sulphur or fresh insect powder 

 dusted well among the feathers is found to be effi- 

 cient. Fowls are sometimes placed in compara- 

 tively tight boxes with their heads protruding 

 through close-fitting openings, the box then being 

 filled with sulfur fumes for several minutes. This 

 is said to completely destroy the pests and in no 

 way to injure the fowls. 



When poultry-houses become infested with lice 

 a complete cleansing of the building is required. 

 Movable fixtures should be taken out and the 

 walls thoroughly washed and cleansed. The interior 

 should be freshly whitewashed or sprayed with 

 chlorides or other efficient insecticides. Kerosene 

 emulsion is effective if the spraying is thoroughly 

 done. Some modern spraying machines are so 

 constructed that kerosene oil may be mixed with 

 water in a fine spray to answer every purpose. This 

 method is easier than to apply the kerosene in the 

 form of a soap emulsion.
