The best method of fly control is
to eliminate their breeding in the first place.
Unless breeding conditions are especially favorable,
adult fly populations will not increase rapidly when
temperatures are below 60 degrees F. Therefore large
scale fly control programs will generally be
warranted only during the summer months. A good
general sanitation program will probably be all that
is necessary to keep the fly problem at a minimum
during the remainder of the year.
A concrete block trash
burner can eliminate virtually all household
garbage. My trash burner shown at left is 4
feet wide, 4 feet high and 5 feet deep.
The top door is 15 x 14", with cast iron
grill one block (8") below the bottom of the
door on top. Anything that will fit
through the top door can be burned, and the
ashes removed through the bottom door and
used on the garden. Food cans have the
galvanizing burned off and then will quickly
rust away. With all garbage burned,
there is no food for flies!
Window screening is of prime
importance, but even a screen door will not keep a
determined fly out because of the numerous times a
day people come in or go out: the fly waits, then
flies in when you do. So we are now reduced to the
flyswatter...not a pleasant task to swat that fly off
your coffee cup.
Indoors, flies can be
killed through the use of common fly spray, a
synthetic pyrethroid, which is formulated
specifically for flies and does not injure humans.
The room only needs to be evacuated for a few minutes
while the spray kills the flies, then the windows
(screened) may be opened and the room ventilated. Fly
control spray around exterior doors works extremely
well, and is available from most feed and seed
stores: they are used extensively in and around horse
stables and cow barns.
All sewage disposal
facilities must be constantly maintained to
eliminate fly breeding. If latrines or outhouses must
be used, ventilation must be provided but securely
screened, all exposed surfaces washed daily with lye
water, and the pit or trench contents sprinkled with
lime, kerosene, or used engine oil. Any type of oil
is a very good larvicide.
Organic Phosphates are
rather deadly insecticides (nerve gases!), but can be
used as bait for flies or used as a wettable powder
and sprayed on areas which require complete coverage.
Sevin (carbaryl) or Malathion can be sprayed
following the directions on the container, or mixed
with 25% sugar and a little water to make a paste,
then set out for flies. Be absolutely sure to keep
these products away from small children!
Insecticides are poison and
special care must be taken to prevent:
Animal wastes should be
collected and buried under at least 4 inches of
earth. Manure can be used in making a compost pile
that also utilizes household organic material, then
covered with a layer of dirt, plus grass clippings or
straw, etc.. The result will be friable, rich compost
to use if gardening is possible, and the layer of
dirt will keep flies away.
