Abstract This study described for the first time, the synthesis of a greener, safer, and more effective termiticide using a bio-based surfactant, N-acyl glycine derived from palm oil for the control of Microcerotermes diversus. Laboratory findings showed that the highest repellent activity was observed in N-acyl glycine surfactant (83.33%) at 50 ppm. In addition, N-acyl glycine surfactant also exhibited substantial time and concentration-dependent anti-termiticidal activity in which the highest termite mortality was observed after 3 days of exposure at 50 ppm of the surfactant (100%). Furthermore, 32.49 ppm concentration of N-acyl glycine surfactant (LC50 = 32.49 ppm) attained 50% of termite lethality. The current innovated termiticide with the use of N-acyl glycine surfactant offers a better efficacy, lower cost, and prevents the use of dangerous termiticides that are critical in creating a more sustainable environment, and controls Microcerotermes diversus at the same time.
