+Of 15 natural products isolated from essential oil components extracted from the heartwood of Chamaecyparis nootkatensis, "...nootkatone from Alaska yellow cedar was the most effective of the eremophilane sesquiterpenes against ticks (LC50 = 0.0029%), whereas the nootkatone grapefruit extract exhibited the greatest biocidal activity against fleas (LC50 = 0.0029%). Mosquitoes were most susceptible to one of the derivatives of valencene, valencene-13-aldehyde (LC50 = 0.0024%), after 24 h. " \\

 Cedarwood Alaska essential oil (steam distilled from fresh sawdust) combines spicy, aromatic and woody aspects with grapefruit notes, due to its nootkatene and nootkatone content. It is less camphoraceous and smoky, but stronger and longer lasting than regular Cedarwood EO (from Juniperus virginiana).\\
