Can you tell me what to use as a spray to kill the flies in my stable?
In the early, morning the ceiling and sides are thickly covered with the
pests partly dormant but not enough so that they can be swept down and
killed. What spray can I use that will destroy them?
It is difficult to kill flies by spraying them. You can, however, spray
the sides and ceiling of the barn with a spray of epsom salts (sulphate
of magnesia) using about a cupful to the gallon, which will prevent them
from gathering there. And since prevention is better than cure, flies
can be kept from gathering around by, destroying their breeding places,
if those are under one's control, by having all manure and litter
removed before the flies have a chance to develop. The following may be
found useful to readers as a spray to keep away flies: Fish oil, 2
quarts; kerosene, 1 quart; crude carbolic acid, 1 pint; oil of
pennyroyal, 1 ounce; oil of tar; 10 ounces. Mix thoroughly and apply in
a fine spray. The following has been successfully used to repel flies
from cows: Nitro benzine, 5 ounces; carbolic acid, 3 ounces; kerosene
oil, 3 ounces; sol. formaldehyde, 1 ounce; fish oil, 1 1/2 quarts. Mix
and just touch the hair with the mixture.
