Ticks feed on blood, are vectors of tick-borne diseases and cause considerable skin damage to livestock. They are commonly controlled using commercial acaricides, which are expensive to the rural farmers, causing them to resort to alternative tick control methods. The objective of this study was to assess the acaricidal properties and safety of some materials (Ptaeroxylon obliquum, Aloe ferox, Lantana camara, Tagetes minuta, Used engine oil and Jeyes fluid, used by rural farmers to control cattle ticks in the Eastern Cape Province, South Africa. A total of 52 cattle were divided into 13 experimental groups with 4 cattle in each. Jeyes fluid at 76.8% concentration and Used engine oil had an efficacy that was almost similar to that of the positive control Ektoban® (Cymiazol 17.5 and cypermethrin 2.5%). Extracts of L. camara at 40% concentration had an efficacy of 57% while A. ferox, P. obliquum and T. minuta were not effective. The test materials had no irritation effect on rats. The study revealed that the materials rural farmers use as acaricides vary in their efficacy in controlling ticks.
