  • Patent number: 8994529
    Abstract: Embodiments described herein comprise an apparatus and method for controlling and monitoring a mosquito misting system. The apparatus includes a chemical reservoir, a delivery system, a spray system, one or more sensors, a communication network and a misting management unit. The sensors may detect normal and abnormal operations of the misting system and send this data to the misting management unit. The misting management unit may then analyze the data and determine the problem. If the problem can be fixed without personnel, the misting management unit may simply adjust the system and fix the problem. If the problem requires personnel, the system may automatically schedule the service call based on a number of criteria.

    Abstract: An apparatus and a method are provided for killing insects on vegetation using an insecticide, where the insecticide does not contact the vegetation. In one embodiment, an absorbent material is placed on an upper surface of a disc mower. The absorbent material is soaked with insecticide, and as a tractor moves the mower through a field of hay, insects land on the insecticide-laden material and die from the toxic effect of the insecticide. In another embodiment, an L-shaped blade outfitted with an insecticide-laden mat is mounted transverse to the front of an all-terrain vehicle or a tractor, which is driven through a field. The blade, or alternatively a feeder bar attached to the blade, brushes the tips of vegetation in the field, causing bugs and insects to fly, fall or jump from the vegetation onto the insecticide-laden mat, where the insecticide kills some, most or all of the bugs and insects.

    Abstract: A device for safely exterminating and removing insects and their nests includes a mesh basket supported on the distal end of a telescopically extendable pole. The basket is structured to partially collapse and includes a rubber gasket around an open top for sealed engagement against the surface surrounding the nest, thereby effectively containing the nest and capturing flying and crawling insects in the basket. A pressurized canister containing a chemical substance snaps into operable position on the pole, near the basket. A handle on the proximal end of the pole includes a trigger for actuating release of the chemical substance from the pressurized canister and towards the nest, thereby killing the captured insects. A blade supported within the basket enables removal of the nest from the surface after all of the insects have been exterminated. A splash shield removably attaches to the pole, below the basket, to protect the user from the chemical sprayed on the nest.
