EXPEKIMENTS AGAINST CHICKEN LICE AND DOG FLEA. 15 



RECOMMENDATIONS. 



A thorough dusting with good fresh pyrethrum powder is a simple 

 and effective remedy against dog fleas. The powder can be easily 

 applied by means of a hand dust gun, an old sugar shaker, or simply 

 a tin can with small holes punched in the cover. It should be freely 

 dusted over all parts of the body and well rubbed into the hair. If 

 the dog is dusted in a shallow box or on an old blanket or a sheet of 

 paper, the fleas, which will drop off in a stupefied condition, can be 

 collected and burned. 



Finely powdered naphthalene or paradichlorobenzene will be 

 found effective if thoroughly rubbed into the hair and can be applied 

 in the same manner as pyrethrum. 



Where dogs are given regular baths, the addition of some of the 

 common emulsified coal-tar creosote preparations generally sold as 

 " emulsified coal-tar disinfectants," " coal-tar creosote dips," or 

 " stock dips," or some emulsion containing cresols, phenols, or hydro- 

 carbon oils, to the water at the rate of 1 to 130 (2 tablespoonfuls to 

 the gallon) will be found very effective. 



In considering the control of fleas it should be remembered that 

 destroying those on the dog affords only a temporary relief, unless "all 

 breeding places are eliminated at the same time. 14 



If the dogs themselves are carefully dusted or washed and their 

 kennels and sleeping places properly treated the flea problem will be 

 solved. 



n A full discussion of methods for the control of flea breeding will be found in Farmers' Bulletin 897, 

 U. S. Department of Agriculture, "Fleas and Their Control," by F. C. Bishopp.
