It has a high control effect on larvae of stored pests that are generated in the sedimentary layer of cereal powder, which was difficult to control by conventional pesticide spraying and smoke treatment, and in places where cleaning of cereal powder is difficult. The three-dimensional insect repellent sheet (10) contains an insect growth controlling agent on at least the surface (1a) and has a three-dimensional surface constituting a concavo-convex structure. 1a) is included in at least a part of the uneven surface.従来の殺虫剤散布及び燻煙処理では駆除が困難であった穀物粉末の堆積層内を発生源とする貯穀害虫の幼虫に対し高い駆除効果を有し、かつ穀物粉末の清掃が困難な場所であっても簡便な駆除を実現することを目的として、立体防虫シート（１０）は、少なくとも表面（１ａ）に昆虫成育制御剤を含有するとともに、凹凸構造を構成する立体表面を有し、表面（１ａ）は、凹凸表面の少なくとも一部に含まれる。
