The present article reports the in vitro toxicity of the seed of Millettia ferruginea (Berbera) for the first time against the larvae and mature ticks of Boophilus decoloratus. The 20%, 40%, 60%, 80% and 100% concentrations of the seed oil were found to kill all (100% mortality) larvae after 16hr, 12hr, 8hr, 6hr and 2hr respectively. The 100% concentration of the petroleum extract (oil) of the seed caused 100% mortality of adult male, adult female and fully engorged female tick after 5hr, 7hr and 12hr respectively. The ischolar_main and ischolar_main bark showed less toxicity while leaves did not show any activity. Among petroleum ether, acetone and methanol, the acetone extract showed highest acaricidal activity.
