ABSTRACT:
A method and device for metered delivery of an insecticidal liquid into a room for the purpose of repelling or killing flying insects, wherein the liquid is ejected in small quantities from a bubble-jet type liquid emanator device at an ambient temperature. The ejected droplets may also be charged to (−1×10−4C/Kg) by passing the droplets through a static field which will cause the droplets to be attracted to the positive charge which exists across the insects cuticle. Other applications include dispensation of fragrances and air fresheners into a room.
