Conirol. Any arrangement which prevents the mites 



from gaining access to the fowls during the hours of 

 roosting will serve as a satisfactory check on these pests, 

 and this, combined with the use of lime and sulphur, as 

 suggested for the fowl tick, will give a practical immunity 

 from their attacks. Of course, cleanliness is a prime 

 requisite in connexion with all parasites of poultry. All 

 droppings should be removed every day, or at the very 

 least twice a week. The use of a sticky substance, or 

 kerosene, at the ends of the perches, as already suggested 

 for the fowl tick, is very useful in this connexion 



Fowls are often seen with deformed or scabby legs 

 a condition resulting from the presence of a burrowing 

 mite, the itch mite of fowls (Sarcoptes mutants, Robin and 

 Lang). Fowls suffering from this pest should not be 

 introduced into a flock where it does not occur. 



Badly infested fowls should be killed, but in cases of 

 mild infection the application of oily ointments to the 

 scabs will result in their removal and in the death of the 

 mites. Care must be taken in the use of oils on the feet 

 of fowls, as an excess might produce an undesirable effect 

 on the normal scales.
