Mange and Lice Control
A reader asks:
Is there anything new on the
market for mange and hce con
trol? It always seems what worked
last year doesn’t do the job this
year.
Dr. Trayer Comments:
Probably the biggest fault of any
mange or hce program is the lack
of follow-up. Often times the
producer will treat the animals
once and then consider the
problem to be under control.
However, when looking at the life
cycle of the parasite one has to
realize there is a 21 to 35 day period
between the egg and the adult
female’s egg production. One
treatment will kdl the adults, but
30 days later the problem begins
all over again.
If you are a seasonal producer, a
once a year treatment may seem
to clear up the problem because
you are not handling the hogs as
often. Therefore, the problem goes

unnoticed. Lice and mange control
is a real problem tor swine
producers. It should be controlled
or eliminated from your herd if
possible. The problem is likely to
cost you 10 to 20 percent in feed
consumption on your finishing
floor. It is also a problem with the
breeding stock as it can lower the
blood iron content thereby making
the offspring less healthy.
I have found a product called
hnspray, primarily lindane which
is emulsified and then sprayed on
the animal, to work fairly well.
However, it must be used in the
proper dosage and used in the
proper rotational time interval. It
should be sprayed once, and two
weeks later sprayed again.
When we speak of lice, they are
external parasites haematopo suis
that can be seen with the naked eye
usually behind the ear or
somewhere on the warmer parts of
the body in the winter.
The other external parasite most
? S
/ \
commonly recognized m the
United States is the mange mite,
sarcopes scabiei, which is
microscopic and can be noticed
only by the effects it has on the
animal. As the mite burrows
between the layers of the skin it
makes a tunnel. The animal then
begins a drastic and constant
scratching to try to stop the
migration of the mite. As the
animal scratches he wastes energy
and does not eat which creates a
serious problem.
There are also blood sucking
species and the loss of blood will
predispose the animal to anemia
and can cause low blood iron levels

particularly in breeding stock..
Death is rare, yet, there may be a
severe loss of protein or the
deletion of iron. The infestation
may migrate down through the ear
drum and cause an infection which
will then migrate into the brain
and cause the hog to circle.
In general lice are visible to the
naked eye and are diagnosed
easily; while the mites are harder
to see and can best be diagnosed by
the scratching, head shaking, or
ear biting done by the animal.
Once the problem is identified
you have three choices. One is to
ignore the problem and live with it.
Two, is to try and control it with
the insecticides that are available.
It has been reported, but never
proven that there can be a
resistance built up to certain
chemicals. The third choice is
depopulation and repopulation,
with breeding stock that are free of
lice and mange.
If you are really serious about
controlling lice and mange, one
solution is to build a well
constructed dipping vat. Make

sure it is deep and long enough to

Tanks are probably the easiest and
most successful method of malting
sure the animal is completely
treated with insecticide. For more
information on tanks contact me
(Dr. Trayer), your extension agent
or an equipment dealer.
Insecticides may also be sprayed
on the animals. However, caution
should be used so you protect
yourself and make sure that the
animal is completely covered with
insecticide especially in the ear
canal.
Be sure to read the instructions
on the chemicals. One-particular
chemical, toxaphane, can cause
neurological problems if applied at
the wrong time. My preference as
previously mentioned is linspray.
The third option of depopulation
and repopulation, should only be
used in extreme cases. Many swine
producers can verify that their
herds have never had these
problems and these hogs are called
