Abstract: An insect exterminating device comprising a bowl shaped container having a shaft centrally disposed extending upwardly, the shaft being rapidly rotated by an electric motor at a representative speed range of between 1,200 and 3,000 rpm, the shaft having a disc secured to its upper end region but positioned below the plane of the rim of the container, and a flexible nylon cord extending radially outwardly from opposite sides of the disc. As the shaft rotates, the nylon cord is extended reaching from the center of the container to approximately the peripheral wall, the rotation being rapid enough to strike and kill insects such as flies which enter the container, attracted therein by bait placed on the bottom. When the shaft is not rotating, the flexible cord lies limp. The bait may consist of molasses mixed with various types of feed, or any edible material which attracts insects preferably containing sugar, honey or other sweet ingredient.
