Horn flies are bloodsucking insects that can be seen on the backs and
sides of beef and dairy cattle during most of the summer. These flies
spend virtually all of their time on animals. They use a tubular
mouthpart to pierce the skin and get a blood meal.

Face flies are one of the most difficult pasture pests to control. They
are on cattle only for short periods of time during the day and stay
mostly on the head, which is difficult to treat with insecticides. Face
flies use an abrasive sponging mouthpart to stimulate tear flow from
the eyes.

The stable fly and house fly are the major insect pests associated with
cattle feedlots. The stable fly irritates cattle by biting and feeding
on blood, causing cattle to gain less weight. The house fly is more of
a nuisance, that causes irritation to people at or near the facility.

Lice are small, flat-bodied insects with legs modified for grasping
hairs. They cannot survive off of the animal for more than a few days.
Sucking lice, with their narrow, pointed heads, are blood feeders.
Biting lice feed by scraping material from the skin and base of the
hairs.

Insecticide-impregnated cattle ear tags release small amounts of an
insecticide which are distributed over the animal during grooming or
rubbing. In general, ear tags have provided excellent, long term
control of horn flies and a reduction in face fly numbers.
