US Patent 7703236 Method and apparatus for killing insects

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.
