Aqueos extract of Chromolaena odorata was evaluated for repellent activity against Periplaneta americana under laboratory conditions. Periplaneta americana were placed in polystyrene boxes applied with four (4) different concentration of Chromo/aena odorata extract (10%, 25%, 50% and 100% and distilled water as control) and observed for 48 hours. The repellency value was obtained by using two way analysis of variance (ANOVA). The interaction between concentration and time was not significant. Yet, there were significance in difference concentration and also significance in difference time. The extraction showed excellent repellency in 100% concentration, followed by high degree of repellency in 50%, but other concentrations has lower repellent activity. Chromolaena odorata has good potential to use as cockroaches repellent. Therefore, it can be used as alternative natural product for controlling Periplaneta americana.
