An object is to provide a high insect control effect on larvae of stored grain insect pests that occur in a deposit of grain powder, which have been difficult to control by conventional insecticide application or fumigant treatment, and make it possible to easily carry out control even in places that are difficult to clean to remove grain powder. A three-dimensional insect control sheet (10) contains an insect growth regulator at least in a front surface (1a) and has a three-dimensional surface that forms a structure with an irregular profile. The front surface (1a) is at least part of the surface with the irregular profile.
