Abstract: The present invention is directed to an ultrasonic repellent humidifier for dispersing insect repellant into the air as a micro fine repellent vapor. A repellent tank provides rhodinol and cedarwood oil based repellent to a repellent well. An ultrasonic transducer is positioned in the well beneath the level of the repellent.
