An insect killing system is disclosed which comprises a circulation chamber within which steam is allowed to flow and circulate in a transverse or horizontal direction and a differential insect killing cell which forces the steam within the circulation chamber to flow in a vertical direction. In this insect killing system, by guiding the steam in the circulation chamber maintained at preselected temperature and humidity into the differential insect killing cell, the product temperature of fruit core temperature of raw fruit can be maintained at a desired level so as to kill out the maggots and eggs of insect pests such as orange flies and melon flies attaching to the raw fruit contained within the differential insect killing cell.
