Bishopp and Wood recommend crude petroleum as the most ef- fective agent and one that retains its killing power for weeks. To improve its spraying quality it may be thinned with one part of kerosene to four parts of crude oil. They likewise find arseni- cal dip such as used for dipping cattle to be fairly satisfactory in killing mites when applied sev- eral times.

Repp recommends preparing kerosene emulsion as follows: One-half pound of laundry soap or whale-oil soap is shaved fine and dissolved in 1 gallon of water. The soap is best dis- solved if the water is nearly or quite at the boiling point. When the soap is dissolved and the water is hot it is removed from the fire, 2 gallons of kerosene oil is added, and the mixture is agi- tated or churned violently until emulsion is formed. The best way to produce the emulsion is to pump the liquid back into the same con- tainer through the pump until the mixture becomes creamy. To make a ten per cent emulsion, 17 gallons of water are added to the 3 gallons of stock mixture; to make a fifteen per cent emulsion, 10 gal- lons of water are added to the 3 gallons of stock mixture. Subsequent to spraying with kerosene emulsion it is desirable to dust the entire interior of the Fig. 48. Female chicken tick after houses with a mixture of air slaked feeding Greatly enlarged.
