Field trials of the natural compounds, nootkatone and garlic, for the control of blacklegged tick, Ixodes scapularis

There is an increasing interest in natural and organic chemistries to replace or assist synthetic acaricides for the control of the blacklegged tick Ixodes scapularis, the vector for the agents of Lyme disease, human granulocytic anaplasmosis and human babesiosis. We report the efficacy at residential properties of the two formulations of nootkatone, an essential oil extract from Alaska yellow cedar, and garlic for the control of I. scapularis.
