An insect control sheet containing a Cry polyhedron prepared by fixing an insecticidal protein (a Cry toxin) produced byto a polyhedron of polyhedrin protein is provided. The insect control sheet contains the Cry polyhedron and is used by floating on water. The insect control sheet is floatable on water, and includes a pure matrix layerand a toxin-containing matrix layercontaining the Cry polyhedronwhich are layered on the underside of a sheet-shaped first sheet substrate. The pure matrix layeris composed of a degradable or water-soluble second material and the toxin-containing matrix layeris composed of a degradable or water-soluble third material and the Cry polyhedron. The toxin-containing matrix layer sustainably releases the Cry polyhedron to the water on which the insect control sheet is floated.
