Interpretive Summary:

Technical Abstract: Supercritical carbon dioxide (70°C, 4,000 psi) was used to extract cedarwood oil from Eastern redcedar, Juniperus virginiana L. The CO2-derived oil was tested for biological activity against several species of arthropods, including mosquitoes, ticks, houseflies, and ants. The cedarwood oil was found to be toxic to all species tested and lethal concentrations were determined. The cedarwood oil was also found to be repellent to ants in a field trial. Cedarwood oil is Generally Recognized as Safe (GRAS) and has potential for use as a natural pest management tool.
