be given to spraying the under side 

 of the dropping boards and roosts, 

 especially where the roost joins the 

 support (See Figure 176.), as these 

 are favorite hiding places for mites. 

 The poultry house that is kept 

 clean and has plenty of sunlight 

 and ventilation is usually free from 

 mites. A very good way to erad- 

 icate this pest is to spray the inside 

 of the house or to whitewash it. 



Whitewash. An effective whitewash that has been used 

 for this purpose is made as follows: Slake half a peck of 

 hme and dilute it with 20 gallons of water. Add 1 pound 

 of salt previously dissolved in water. To this mixture add 

 2 quarts of crude carbolic acid or 1 gallon of stock dip and 

 apply with a spray pump or brush. 



A good spray. Another very effective method that can 

 be used to kill mites is to spray the roosts, nests, and all 

 cracks or crevices with kerosene, crude oil, or some wood 

 preservative manufactured from coal tar, such as creolin, 

 creosote, etc. 



If possible, the spraying should be done with crude oil 



or wood preservative 

 rather than kerosene, 

 inasmuch as it is neces- 

 sary, when kerosene is 

 used, to continue to spray 

 every 10 days or 2 weeks 

 throughout the warm 

 weather, once the mites 

 have gotten started.
