The natural ingredients used in this study are tuba roots, red betel leaves, tobacco leaves, and soursop leaves. The purpose of this study was to determine the effectiveness of natural substances on tick mortality. This research method using type research study literature. Data collection using secondary data. The source is taken in relation to the effect of natural substances on tick mortality. Source-the source is obtained from scientific papers and journal. In this research, the tuba roots and red betel leaves were carried out using sample of 10 ticks. The results of LC values are 1.50% and 5.4%, respectively. For soursop leaves and tobacco leaves using a sample of 5 ticks, the LC values were 0.12% and 11.5%, respectively. Based on the LC value, it can be concluded that soursop leaves have an effective effect on tick mortality with a value of 0.12%.} }
