To find the lice, part the feathers; the lice will be found running over 
the skin or bases of the feathers. A favorite location for the lice is under 
the wings where the temperature is warmer, although they may be found 
on any part of the body. 
Lice may be found at all seasons of the year, but are more common in 
the hotter months of July and August. In these months, conditions are more 
favorable to their propagation. 
TREATMENT OF INFESTED BIRDS AND ERADICATION OF LICE.— 
The chickens should be dusted with insect powder (pyrethrum) or pyrethrum 
and sulphur equal parts, or a combination of these with tobacco dust, which 
can be secured from a tobacco factory. This powder can best be dusted 
among the feathers by aid of a powder gun, which can be secured at a drug 
store. It can also be placed in the dusting places. In ridding the birds of 
lice, it will be well to keep in mind that frequent dusting with powder will 
be necessary, as the eggs or nits fire not all likely to be killed by the powder. 
Another means of ridding chickens of lice is to dip them in a five per cent 
solution of Creolin, Kreso dip, or the same per cent of Zenoleum. 
After the flock has been freed from lice, care should be exercised that 
a reinfestation is not brought about by the introduction of lousy birds. The 
henhouse in which lousy birds are located should be thoroughly and fre¬ 
quently cleaned and the walls whitewashed. The whitewash should contain 
in it some parasiticide as* carbolic acid five per cent, creolin five per cent, or 
corrosive sublimate one part to a thousand. The roosts should be scrubbed 
with boiling water, and after drying in the sun, should be saturated with 
kerosene. If the hen house be tightly closed and thoroughly fumigated with 
sulphur, it will aid in destroying lice or other parasites that may be in the 
cracks and crevices and difficult to reach with the whitewash. The litter 
and straw should be removed from the nests and burned, and the nests should 
be disinfected and new straw provided. Before refilling with straw, an inch 
of slaked lime should be placed in the bottom.
