The Sheep Tick and Its Eradication by Dipping

"The sheep tick, while not a true tick, is a blood-sucking parasite which infests sheep on both farms and ranges. It is widely prevalent and spreads rapidly, especially among the close-herded range flocks, where it may cause much damage and loss. The nature and habits of the tick are described, also methods of identifying it. The only practicable way of destroying the pest is by dipping the sheep. Two dippings are necessary about 21 days apart, as the fist dipping may not destroy all the pupæ (eggs), and these may subsequently hatch a new brood. Several kinds of dips are used successfully. Of the home-made dips the one found to be most efficacious is the lime-sulphur-arsenic dip. Full directions for making this dip are given in this bulletin. Methods of dipping large and small flocks are discussed, including plans of a wooden and a cement vat, showing details of construction."--Page 2.
