Household insects such as bed -bugs, ants in floors and 

 termites in woodwork may be destroyed by the free use of 

 kerosene, and many flying insects which are attracted may 

 be caught in a tray of water and kerosene over which a 

 light is suspended. The insects, flying to the light, fall into 

 the tray below, where they are killed by the film of kerosene 

 on the water. 



Tobacco and Soap. Tobacco and soap is often a conve- 

 nient mixture, especially for house plants, where the smell 

 of whale-oil soap would be an objection to employing that 

 substance. It is composed of : 



Soft soap 1 quart or 



Hard soap J-flb. 



Tobacco refuse J Ib. 



Dissolve the soap in 5 gallons of water, steep the 

 tobacco in 2 quarts of water for 24 hours, strain and add 

 to the soap solution. This mixture is used without fur- 

 ther dilution. 



Crude Oil and Whale-oil Soap. This mixture has a 

 wide range of application and possesses the valuable 

 quality of keeping well. It is sold in Barbados under the 

 name of Lefroy's mixture, Mr. Lefroy being the originator 

 of the compound. 



Whale-oil soap 10 Ib. 



Crude Barbados oil 5 J pints 



Naphthalene 4 oz. 



Heat the soap in a metal vessel. Dissolve the naphtha- 

 lene in the oil by stirring. Add this mixture to the hot 

 soap, away from the fire, and thoroughly mix the whole 

 by stirring. A nearly solid soap-like substance is produc- 

 ed which is prepared for use by rubbing up or stirring it 

 in water. Use at the rate of 1 ft. to 8 Ib. in 10 gallons of 

 water. 



Sulphur. Sulphur may be used either dry or as a 

 spray. When used dry, it may be applied by itself or in 

 a mixture with varying amounts of lime. When used as 

 a spray, 1 Ib. in from 2 to 4 gallons of water is a con- 

 venient strength. Sulphur has a special value in combat- 

 ing mites of all sorts, including ticks, poultry mites, red 

 spider, leaf-blister mite and the orange rust mite. It is 

 also a constituent of many ointments, applied in the case 

 of mange, itch and similar affections, which are due to the 

 presence of mites.
