In this study, the chemical composition, repellent, and oviposition deterrent effects of five plant essential oils (EOs) extracted from <i>Lantana camara</i> (Verbenaceae), <i>Schinus terebinthifolia</i> (Anacardiaceae), <i>Callistemon viminalis</i> (Myrtaceae), <i>Helichrysum odoratissimum</i> (Asteraceae), and <i>Hyptis suaveolens</i> (Lamiaceae) were evaluated against <i>Aedes aegypti</i>, <i>Anopheles gambiae</i>, and <i>Culex quinquefasciatus</i>. When tested at 33.3 µg/cm², <i>L. camara</i>, <i>S. terebinthifolia</i>, <i>C. viminalis</i>, and <i>H. odoratissimum</i> were effective repellents against <i>Ae. aegypti</i> (89%, 91%, 90%, and 51% repellency, respectively), but they were less repellent against <i>An. gambiae</i> (66%, 86%, 59%, and 49% repellency, respectively). Interestingly, <i>L. camara</i>, <i>S. terebinthifolia</i>, <i>C. viminalis</i>, and <i>H. odoratissimum</i> exhibited 100% repellency against <i>Cx. quinquefasciatus</i> at 33.3 μg/cm². In time-span bioassays performed at 333 μg/cm², the EO of <i>L. camara</i> exhibited 100% repellence against <i>Ae. aegypti</i> and <i>An. gambiae</i> for up to 15 min and against <i>Cx. quinquefasciatus</i> for 75 min. The oviposition bioassays revealed that <i>L. camara</i> exhibited the highest activity, showing 85%, 59%, and 89% oviposition deterrence against <i>Ae. aegypti</i>, <i>An. gambiae</i>, and <i>Cx. quinquefasciatus</i>, respectively. The major compounds of <i>L. camara</i>, <i>S. terebinthifolia</i>, and <i>C. viminalis</i> were <i>trans</i>-β-caryophyllene (16.7%), α-pinene (15.5%), and 1,8-cineole (38.1%), respectively. In conclusion, the <i>L. camara</i> and <i>S. terebinthifolia</i> EOs have the potential to be natural mosquito repellents.
