CONTROL OF PESTS ON BEEF CATTLE
P. G. Koehler*


Pest of domestic and agricultural animals are a
serious threat to the animal since many feed on body,
tissue such as blood, skin, hair and feathers. The
wounds and skin irritation produced by these pests
often result in discomfort and irritation for the
animal. Many pests are also vectors of disease. In
general, infested animals cannot be healthy or effi-
ciently managed.
Although pesticides are used to protect animals
from pests, it is important to remember that any
pesticide should be considered an active poison. The
successful control of pests requires careful mixing
and application of recommended pesticides ac-
cording to label directions. It is also necessary to ap-
ply pesticides properly to prevent injury to the
animal. Never use more insecticide than is recom-
mended. Overdoses of pesticides are not only poten-
tially fatal, but also can weaken animals making
them susceptible to disease. It is also against the
law to apply a pesticide contrary to the label or you
could be fined.
Many pests of animals can be controlled by apply-
ing small quantities of pesticides to specific areas of
the infested animal. Often most efficient pesticide
application can be made by applying small quan-
tities of pesticide frequently.
Never use more pesticide than is recommended.
Overdoses of pesticides are not only potentially
fatal but can also weaken animals and predispose,
them to disease. Young animals, because of their
low body weight, are particularly susceptible to
overdoses of some pesticides.


Precautions

Precautions should also be taken during applica-
tion to insure the safety of the animal. These are:
1. Cover feed and water containers to prevent
contamination during application.
2. Keep chemicals thoroughly mixed in sprayer.
Some formulations will separate unless constantly
agitated, resulting in overdoses and underdoses for
some animals.
3. Do not mix pesticides or load a sprayer where
animals or children may have access to spilled
chemicals.


4. Don't use a pesticide if an oily or gummy film
appears on the surface. The chemical may have
deteriorated in storage.
5. Pesticides should not be applied in combina-
tion or within certain time limits with other
pesticides or drugs. The combination of chemicals
may produce undesirable effects.
6. Sick or stressed stock should not be treated
with some pesticides.
7. Young animals are often susceptible to
pesticides. Read label precautions before spraying
young animals.
8. Do not spray animals with leaking sprayers,
hoses or connections.
9. Certain types of animals are susceptible to
some pesticides. Sensitive animals should not be
treated.
10. Have a special area for cleaning sprayers so
excessive pesticide and wash water does not con-
taminate animals. Keep drainage out of water sup-
plies and streams. Do not let animals into areas
where sprayers are cleaned.
11. Mix only the amount of chemical needed for
the treated animals.
12. Some solvents tend to stay in the air and
cause toxicity problems to animals in the holding
area. To prevent this damage, animals should not be
treated during hot, still afternoons.
In addition to the above precautions, protect
yourself from the effects of pesticides by following
all safety procedures on the label and using accepted
pest control practices.

Pesticide Residues

Many animals are raised for human consumption.
Human food must not contain dangerous amounts
of chemicals in edible tissues. The Federal Govern-
ment through the Food and Drug Administration
guards our food from harmful pesticide residues by
establishing pesticide tolerances. A tolerance is the
amount of pesticide that may remain as a residuue
on a food. The chlorinated hydrocarbons (DDT,
chlordane, dieldrin, aldrin and others) have a zero
tolerance in meat, eggs and milk. It is important
that illegal residues of pesticides not accumulate in
edible tissues. If illegal amounts of pesticides are

found by the Food and Drug Administration, the
commodity may be seized and destroyed. Legal ac-
tion may also be taken against persons and
businesses responsible for the illegal residues.
To prevent illegal residues observe the following
precautions:
1. Use only approved pesticides in the recom-
mended dosage.
2. Follow the prescribed number of days to elapse
between the pesticide application and the slaughter
of the animal or use of edible products such as milk
or eggs. The interval will permit the animal to
eliminate the pesticide from its tissues before pro-
cessing of edible commodities.
3. When preparing backrubbers, use only recom-
mended materials and carriers. Don't use waste
motor oil since it may contain materials which pro-
duce residues.
4. Pastures, forages and feeds should only be
treated with chemicals that will not contaminate the
crop. The prescribed number of days should elapse
between pesticide application and crop harvest or
use.
5. Clean application equipment thoroughly so
residues of previous sprayings are not applied to
animals.
6. Don't feed animals feed or food of unknown
origin unless you are sure it won't cause illegal
residue problems.
7. Do not allow pesticides being applied to nearby
areas to drift onto animals or areas frequented by
animals.
8. Do not allow feed or water to become con-
taminated with pesticides.
9. Do not repeat applications unless the label
specifies that you can.


Problems With Pesticides

Applicators should be aware that certain breeds of
animals may react adversely to certain pesticides or
materials contained in pesticide formulations. Sen-
sitive animals should not be treated or should be
treated only with extreme care. For instance,
Brahman cattle may be sensitive to organo-
phosphate pesticides. If a pesticide label states "Do
not treat Brahman cattle," the pesticide should not
be applied to those animals. Also the skin of some
horses and dogs is sensitive to some pesticide for-
mulations. If there is uncertanity about an animal's
sensitivity, treat a small area of skin and observe
the area for 24 hours before treating the entire
animal.


Individual animals may also react adversely to a
pesticide or pesticide formulation. Sensitive animals
should be identified and treated only with acceptable
chemicals. If an animal does react adversely to an
application, efforts should be made to remove the
pesticide formulation from the animal.
The age, size and condition of an animal is also im-
portant when applying pesticides. Young animals
are generally smaller and consequently more suscep-
tible to pesticides. Care should be taken when
treating young animals, and precautions on the
label should be checked to determine whether it
prevents application to young animals. many insec-
ticides should be applied according to the size of the
animal. Less pesticide should be applied to smaller
animals to prevent toxicity problems. Dusts and
wettable powder formulations are generally less
toxic than emulsifiable formulations. Stressed or
diseased animals are also sensitive to pesticides.
Often the additional stress of a pesticide application
is enough to kill stressed or diseased animals.
Certain precautions can be taken during routine
applications to prevent pesticide problems. These
are:
1. Do not apply pesticides on extremely hot still
days.
2. Do not wet animals with spray or dip during
cold or freezing weather.
3. Use dust formulations whenever possible since
they are generally less toxic dermally and do not
add excessive moisture to the animal. For sensitive
animals use dust or wettable powders.
4. Whenever possible, apply small amounts of
pesticides to specific sites on the animal to control
pests.
5. Frequent treatments with small amounts of
pesticide are preferable to infrequent treatments
with larger dosages.
6. Do not treat stressed or diseased stock, young
animals or small animals without consulting the
pesticide label.
