  • Patent number: 6202343
    Abstract: A dedicated, vacuum operated, electrical capture device has a shaped capture housing having an inner rim carrying conductors for killing or stunning a pest, to cause the pest to release itself from its position on a surface, and a vacuum suction motor assembly to pull the pest through a telescoping section to a final section of tubing which is accessible to facilitate disposal of the pest. A pest collection compartment situated along the air intake tube includes a flexible door for convenient disposal of the collected pests.

  • Patent number: 6134826
    Abstract: A compact insect trapping appliance uses an efficient ultraviolet light mounted from underneath a protective dome to both attract insects and to enable the user to position the appliance to selectively direct the ultraviolet light in a desired direction, away from a line of sight of people near the appliance. The inner walls of the upper, partially open chamber carries a low voltage grid array for deleteriously affecting and disabling insects which alight on the inner walls of the upper chamber. This low voltage grid array produces a low voltage current, and acts fairly slowly and silently to disorient and disable the insect as it makes contact. Once the insect gets becomes sufficiently disabled, it will likely fall directly into, or by its own movements, slide into an entry hole of an conical surface and through a narrow neck of a sound suppression chamber within the appliance.
