Common Insect Enemies 101 



This louse, which gets its name from its crabiike ap- 

 pearance, is shorter and much flatter and broader than his 

 relatives, the body and head lice. And, unlike the body 

 louse, the crab louse does not live in the clothing, but makes 

 his home in the hair of the body. Therefore, it does no good 

 just to put on clean clothes; you must use an insecticide 

 which will kill him on the body. 



In the past, Blue ointment, kerosene in vinegar or olive 

 oil, and derris and larkspur lotions have been used against 

 the crab louse, but DDT powder or the NBIN formula are 

 much more efi^ective, and are not as irritating to tender parts 

 of the body as are derris or kerosene-containing preparations. 



Since the crab louse lives in the hair of the body, all 

 hairy portions, including the armpits, chest, the pubic and 

 perineal region, and the legs should be thoroughly dusted 

 with 10% DDT powder or treated with an emulsion of the 

 NBIN formula, and the powder or emulsion should be rubbed 

 in well with the fingers. One application of the NBIN 

 formula will eradicate an infestation. It should be allowed 

 to remain on the body for at least 24 hours in order to get any 

 wanderers who were hiding out in the bedding or clothing. 

 If you prefer to use the powder, leave it on for at least 2-1 

 hours before you take a bath, and repeat the application in 

 about 8 or 10 days. 



Your Bedtime Companions 



Have you ever noticed how a person aas just after he 

 is shown to his room in a hotel or rooming house? How he 

 tiptoes very carefully over to the bed, grabs the covers, and, 

 with a mighty heave, pulls them down? What he is seeking 

 are some tiny, brown creatures, with the scientific name of
