A pair of agitator tubes having inlets in fluid communication with the exhaust in the shaft direct exhaust from the fan over bait provided to attract the insects. The bait is contained in a receptacle spaced upstream from the shaft and which houses a light source and optionally an auxiliary heat source. The outlets of the agitator tubes are inside the receptacle so that any exhaust diverted from the shaft into the agitator tube will entrain vapors from the bait as the exhaust exits through a vent provided in the receptacle.

  • Patent number: 5400543
    Abstract: A device for capturing and exterminating fire ants includes a container, a primary vacuum unit, and an inlet hose. The primary vacuum unit reduces the air pressure within the container such that air is drawn in through the inlet hose. During a collection operation, a user operates the digging attachment to loosen a fire ant mound and collects the mound contents with the inlet hose. Once the collection operation is completed, the user seals all openings to the container against the atmosphere and connects a secondary vacuum source to a vacuum receiving nipple formed in the container. The secondary vacuum source removes air from the container and asphyxiates the fire ants within the container. The present invention also includes a digging attachment attachable to the inlet hose that allows a user to loosen the contents of a fire ant mound for more effective collection.

  • Patent number: 5323556
    Abstract: The trap includes an enclosure from which it is possible to draw air therefrom thereby reducing pressure therein. An opening is provided in the enclosure which enables outside air to be drawn therein as a result of the reduced pressure, and through which mosquitoes or night flying insects can be sucked inside the enclosure. A container which is associated with the enclosure and is separate from the device that draws air therefrom receives mosquitoes or night flying insects which have been sucked into the enclosure. The insects should be directed toward the container without contacting the air drawing device. By operating the device in an environment loaded with mosquitoes or night flying insects, most if not all of them are collected inside the enclosure.

  • Patent number: 5222322
    Abstract: An insect capture extermination system provides a hollow fluid-type housing having an intake channel. A negative pressure assembly secured within the housing is actuated by a proximity sensor which detects insects at the entrance to the intake channel. Also provided is an inner flow permeable membrane which provides particulate barrier to both protect the negative pressure assembly and to capture and store insects between cleaning of the system. Insects are attracted to an insect attraction element, such as sonic, olfactory and phosphoric elements, and pulled into the intake channel of the housing and captured. The system may be adapted for use with food display counters and in residential structures. A proximity sensor maintains the system in a normally-off mode in the absence of insect activity at the intake channel.

  • Patent number: 5209010
    Abstract: An insect killer comprises a transparent bottle with a removable lid. Entryways are formed in the sidewall of the bottle to allow insect ingress while restricting or discouraging egress. A fan is mounted to the lid and draws air into the bottle through apertures formed in the lid and forces the air out the entryways, propagating the scent of the attractant to the surrounding areas. Striking means are coupled to the fan so that insects flying inside the transparent bottle will be hit by the striking means. The insects so struck will fall into the liquid attractant held in the bottom of the transparent bottle, where they ultimately drown or are stunned to death by other insects.
