The coal tar dips are of two classes, known as creosote dips and cresol dips. They are sometimes home made, but more often are proprietary. Of these dips, the creosote dips are probably the best, for although both are effective in destroying ticks and scabs, the creosote leaves the wool in a clean, soft and pliable condition, while the cresol dip is liable to leave it dry and harsh.
The carbolic and arsenical dips are losing favor with sheep raisers oh account of their poisonous character and they are not highly recommended by the Dep’t of Agriculture.
Sheep should always be dipped twice. The first dipping kills the mites, but usually does not get the eggs, so they should be dipped again, about ten days after the first dipping.
Sheep should remain in the dip for one minute, to destroy ticks, and two minutes for scab, and the head should be plunged beneath the dip just before leaving the tank, except where using carbolic or arsenical dips.
If sheep become infested with ticks or scab, they should be dipped irrespective of the season of the year. Otherwise it is usual to dip them shortly after shearing.
For large flocks of sheep, an elaborate dipping plant, with permanent vat, cooking and heating apparatus, and herding and draining pens is necessary, but for a few sheep on a general farm, a large tub will do and the sheep can be lifted in and out of it onto a draining board which will carry the drippings back into the vat.
