Mosquitoes that light on the ceiling may be easily destroyed with the instrument shown in the sketch. It consists of a cover, such as used on jelly glasses, nailed to the end of an old broom handle A little kerosene Oil is placed in the cover and the device is passed closely beneath the location of the mosquitoes.
