These work by preventing
stable and house fly larvae
from developing in your horse’s
manure. They don’t kill adult
flies, but they prevent new ones
from maturing. Feed-through fly
products come in pellets and are
fed daily during fly season.
Biological controls. The
good news is that flies have
enemies: tiny wasps that feed on
the pupa of the developing fly.
The wasps don’t bother horses or
people, and are so small they’re
barely noticeable. They eat the fly
larvae before they can turn into
full-grown, biting flies. To keep
your property well stocked with
these fly-killing wasps, release a
new batch each month.
Fly traps. Fly traps work
by attracting flies, either through
color or scent. Once the fly lands on
or enters the trap, it can’t escape.
The simplest type of trap uses
a sticky surface to catch flies. The
flies are attracted by the color—
usually orange or yellow—and land
on it. The glue-covered surface
sticks to their feet, keeping them
from flying away.
Other traps use bait to lure
the fly. Some have water inside,
and the flies drown because they
can’t escape. Others simply trap
them inside the container, where
Direct Defense: Spray Away
You’ve done everything you can
to keep flies from advancing into
your territory, but no matter
how hard you try, some of the
intruders still break through
your defenses. Your next step is
to protect your horse with the
direct application of one of the
fly’s biggest foes: fly repellent.
Go to your local feed store and
you’ll see a variety of different
fly sprays, wipe-ons and roll-ons
for sale. Most of these products
contain the active ingredient
pyrethrin, a natural substance
that kills flies on contact and
keeps them from biting.
Pyrethrins work by attacking
the fly’s nervous system, and
provide a quick knockdown after
landing. Flies don’t like the smell
of pyrethrins either, so sprays
containing this ingredient repel
the broadest number of flies.
They might land on your horse,
but they won’t stick around.
Fly repellents are made with
either oil or water as a base.
Oil-based sprays last longer than
water-based, while water-based
products are lighter and usually
don’t smell as strong.
To get the most of your fly
spray, apply them to the areas on
your horse most often besieged
