animal is confined to an area free of fleas, one treatment 
usually is enough. 
Rotenone.—Rotenone is effective but slow acting. 
Buy a powder that contains at least ] percent of rotenone. 
Pyrethrum.—Use a pyrethrum powder containing | 
percent of pyrethrins or a powder containing 0.2 percent 
of pyrethrins fortified with a synergist (2 percent of 
piperony] butoxide or sulfoxide). 
Fleas begin to leave the animal within a few minutes 
after the powder is applied, but they are only paralyzed 
and may recover. ‘Treat the animal outdoors or in an 
enclosure where the paralyzed fleas can be swept up and 
destroyed. 
DDT.—Apply a 5- or 10-percent DDT powder. 
Lindane, chlordane, methoxychlor.—Apply a 1- 
percent lindane powder, a 5-percent chlordane powder, 
or a 10-percent methoxychlor powder. 
Other Animals 
An insecticide powder or spray will control the human 
flea on hogs, goats, and other animals. Apply it to the 
animals and to their quarters or pens. 
To dust the animals, use DDT, lindane. chlordane, or 
methoxychlor in the strengths recommended for dogs. 
Use enough powder to treat the animals thoroughly. 
Apply it with any garden-type duster. 
You may use any of these powders in treating the ani- 
mals’ quarters or pens: but if you use DDT powder, apply 
it in 10-percent strength. 
To spray the animals, wet them thoroughly with an 
emulsion or a wettable-powder suspension containing 0.5 
percent of DDT, methoxychlor, or chlordane, or 0.05 per- 
cent of lindane. Prepare the spray by mixing an emulsi- 
fiable concentrate or wettable powder with water (see 
chart). Apply it with a garden-type compressed-air 
sprayer or a hand sprayer.

spraying would be difficult.
