Fortunately cattle lice do not have
wings. and yet they spread very rap
idly by contact Of animals They
pend their entire life upon the host
and lt removed cannot live longer
than n very few days
As a rule lice are few in number
during the summer months, but upon
the approach Of winter, when the
hair increases in length, conditions
become favorable and the lice begin
TO increase rapidly.
Controi.-Since this red cattle
louse is a biting insect and since it
remains upon cattle throughout its
entire life 1t is the easiest lousc of all
cattle lice TO completely destroy.
Furthermore, il can be destroyed at
any time during the cold winter
months by the use of stomach
poison applied in powder form. The
poison recommended is white pow
der known as sodium fluoride. Local
dealers can supply sodium fluoride or
can obtain il.
The chemical should be busted
lightly into the hair over all parts of
the animal by means OF good dust
gun. II viii require approximately
one pound 10 treat from l6 to 25
head, according to the size of the
animals. Information as to where
dust guns may be obtained will be
sent on request by The Extension
Service, Colorado Agricultural Col
legc
II the work is thoroughly done. all
OF the lice and all the young hatch
ing from the eggs will be destroyed
in one application. However, this
does not insure the animal from re-
infestation If allowed 10 come in con-
tact with untreated cattle. If in
doubt as to the louise being 4 biting
or a sucking species send specimens
to the etomologist of the Agricul-
tural College for determination, or
see your county agent.
Too much emphasis cannot be laid
upon the use of sodium fluoride as
a winter treatment for the red or
biting cattle louse when it predom-
mates, but when sucking lice are
numerous other measures are neces-
sary.
