Germany’s cockroach (Blattella germanica L.) is a residential pest that can be a vector of disease. One of the ways that used to control Germany’s cockroaches is to use toxic baiting. Fipronil and imidacloprid are chemicals used to kill cockroaches. The purpose of this study was to analyze the comparison the effectiveness of the active substances Fipronil and imidacloprid used to control the Germany’s cockroach (Blattella germanica L.). The methods were used in this study include the preparation of test insects, making of toxic bait, test the effectiveness of toxic bait, calculation of mortality and data analysis. The data were analyzed statistically using One Way ANOVA test and probit analysis. ANOVA test results obtained a significance value of 0.00 (P < 0.05), this indicates that there is a significant difference in the percentage of mortality between the treatment groups. The highest mean percentage of deaths occurred in the Germany’s cockroach group was treated with a combination of bait and the active substance Fipronil. In addition, the lowest LT50 and LT90 ​​occurred in the LT50= 28.23 hours and LT90 = 72.10 hours. These results show that the active substance Fipronil was more effective in controlling the Germany’s cockroach (Blattella germanica L.) compared to imidacloprid.
