Introduction: Aedes aegypti and Aedes albopictus are important vectors that transmit arboviruses to human populations.
Methods: Natural products were obtained and tested against larvae collected from the field in Fortaleza, capital of Ceará state.
Results: The essential oils of Syzygium aromaticum (Ae. aegypti LC50 = 32.7 ppm and Ae. albopictus LC50 = 138.1 ppm) and Croton nepetaefolius (Ae. aegypti LC50 = 81.7 ppm and Ae. albopictus LC50 = 76.1 ppm) showed the most intense larvicidal activity.
Conclusions: The essential oils and methyl esters showed greater larvicidal activity than did the ethanol extracts.
