Fly Repellants

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.
