FLEAS 



For fleas on dogs, dust a 10% DDT powder thoroughly 

 into the hair of the animal, along the back from the head to 

 the tail. About 1 tablespoon of powder is sufiicient for the 

 average-sized dog. For perhaps an hour after application, 

 fleas will probably show greater activity with resultant great- 

 er discomfort to the animal; however, the fleas begin to die 

 in about 10 minutes, and after a few hours none are left. A 

 single treatment is sufficient to protea dogs from further in- 

 festation for several days. 



In addition to dusting the animal, treat the sleeping 

 places of the dog, and infested basements and rat burrows 

 with about % lb. of 10% DDT powder or /4 gallon of 5 % 

 DDT solution per 1,000 square feet of floor space. 



For flea-infested floors, rugs, overstuffed furniture, and 

 fabrics, a light application of about 1 gallon of 5 % DDT 

 in kerosene per 4,000 square feet of surface is not only ef- 

 fective against the fleas themselves but also against the flea 

 larvae. A 5 % DDT emulsion or a 2 % % DDT suspension 

 of wettable powder can be used in place of the kerosene 

 spray where staining and the white residue are not objec- 

 tionable. DDT suspensions are particularly advantageous 

 for use on flea-infested lawns, where kerosene might damage 

 the grass. 



For the control of fleas on cats, DDT powder should not 

 be applied directly to the animal since cats lick themselves 

 and might ingest sufficient DDT to make them sick. How- 

 ever, treatment of the sleeping places of cats and other flea-
