Abstract
Abstract A dipper for use in removing mosquito larvae from bodies of water includes a cup and a handle. The cup has a generally frusto-conic outer wall terminating in a laterally extending annular lip. There is a bottom integral with the frusto-conic outer wall. The annular lip and the adjacent areas of the upper portion of the wall form generally diammetrically opposed pouring grooves, which grooves extend below the level of the lip, with the lip being continuous in size and shape throughout the grooves. There is a handle support integral with the cup wall which extends outwardly from the wall and has a coaxially arranged cylindrical opening for mounting the handle.
