SPRAYING CAGES - 
to control chicken mites 
and northern fowl mites 
if it is heavily infested with mites. Apply 1 
pound per 40 square feet of litter surface. 
The percentage of insecticide varies in emul- 
sifiable concentrates and wettable powders. The 
accompanying chart shows how to prepare a 0.5- 
percent spray. To make a 1-percent spray, double 
the amounts. 
NORTHERN FOWL MITE 
Northern fowl mites, which look like chicken 
mites, stay on the fowls. They congregate near 
the vent, tail, and neck, and suck blood. Feathers 
become soiled. Scabs often form on the skin of 
infested fowls. 
Control 
Use 4- or 5-percent malathion dust, or 5-percent 
Sevin dust, in litter for chickens only. Apply 1 
pound of 4-percent dust per 40 square feet of litter 
surface. Apply dust uniformly with a hand- 
operated plunger or rotary duster or with a shaker 
jar. Repeat as necessary. 
PAINTING ROOSTS 
to control chicken mites 
and northern fowl mites 
Apply a 1-percent malathion spray, or a 4- 
percent malathion dust, or a 5-percent Sevin dust, 
or 0.5-percent Co-ral dust, directly to individual 
birds or to flocks. Use 1 gallon of spray or 1 
pound of dust per 100 birds. 
Nicotine sulfate (40-percent nicotine) or 3- 
percent malathion emulsion may be used as a roost 
paint. Apply 1 pint per 150 feet of roost one-half 
hour before roosting time. Repeat as necessary. 
Do not use Co-ral more often than once a week. 
Do not apply Co-ral less than 45 days before 
slaughter. 
Do not apply Sevin less than 7 days before 
slaughter. 
SCALY-LEG MITE 
Scaly-leg mites burrow under the scales of the 
fowls’ feet and lower legs. The burrowing causes 
itching and irritation. The scales are pushed up 
from the legs, scabs or crusts form around them, 
and they are easily detached.
