MOSQUITOES 

 In Homes 



Mosquitoes in homes can be killed with the same DDT

 table powders — can be used to kill mosquitoes that venture 

 around the premises over a period of months. 



Around Premises 



To cut down the mosquito population, it is also a good 

 idea to either spray the lawn and shrubbery around the house 

 with a 2 /4 or 5 % DDT emulsion or dispersion, or to sprinkle 

 them with a 5 or 10% DDT powder. 



In Breeding Grounds 



For effective mosquito control, the breeding grounds 

 should be treated with about /4o pound of DDT per acre. 

 The DDT can be applied in the form of a kerosene or other 

 oil solution, as an emulsion, or as a dispersion of wettable 

 powder in water. For large areas of swampland or vege- 

 tation, application by airplane is very effeaive. For stag-

 will kill the larvae of most species of mosquitoes.
