158 HOUSEHOLD INSECTS 



of wide infestation. Van Dine, entomologist in Hawaii, 

 has had the same experience and his method of treatment 

 is so good that it is quoted here. 



"(1) If the lawn is infested, cut the grass as close to 

 the ground as possible and burn the refuse. Exposure 

 to the sun and air will be detrimental to the development 

 of the larvae. Keep the lawn well watered. 

 • " (2) Clean out and burn all refuse from beneath the 

 infested dwelling, leaving the surface of the ground as 

 bare as possible, and apply an even dressing over the sur- 

 face of lime, sulfur, and buhach at the rate of 20 pounds 

 of air-slaked lime to 3 pounds of powdered sulphur and 

 1 pound of buhach, thoroughly mixed and dry. Spray 

 the underpinnings of the house and the drives and walks 

 (if the latter are sand, gravel, or dirt) with kerosene 

 emulsion at the rate of 1 part of stock solution of the emul- 

 sion to 10 parts of water. 



" (3) If dogs are owned, provide a room for them to 

 sleep in and keep cats out of the house. Wash with strong 

 soapsuds the floors of the room where the dogs are to 

 sleep, and sprinkle afterwards, when dry, with a liberal 

 amount of buhach. Use a liberal amount of buhach in 

 places where the dogs have been in the habit of sleeping 

 and remove and burn from such places all refuse, old 

 sacks, matting, etc. Every week or so take the dogs to 

 the room provided for them and brush them thoroughly 

 with a strong, stiff brush. Afterwards collect the result- 

 ing hairs and the bedding and burn or immerse the sacks 

 in hot soapsuds and hang in the sun to dry. Then wash 

 the room out as before and sprinkle with buhach, and return 

 the bedding. The dogs should be washed regularly, 

 a little creolin being added to the water.
