PROBLEM TO BE SOLVED: To provide a pest repelling material mainly targeting floor and wall or the like of the room that has sustainability for a long time, and also has a high safety property, and to provide a method for repelling pest using the same.SOLUTION: The problem is solved by a pest repelling material in which a solution containing a naturally occurring component as an active ingredient is penetrated into a base material, and is characterized in that the material is used by applying the solution to the surface to be treated. In particular, when the solution contains a cyclic monoterpene alcohol (A) and/or a cyclic monoterpene ketone (B) as the naturally occurring component and is a solution containing a cyclic sesquiterpene (C), it is preferable for solving the above problem.SELECTED DRAWING: None【課題】主に室内の床や壁等を対象とした、長時間の持続性を有し、また、安全性の高い害虫忌避材や、それを用いた害虫忌避方法を提供する。【解決手段】天然由来成分を有効成分として含有する溶液を基材に浸透させた害虫忌避材であって、被処理面に該溶液を塗布して使用されることを特徴とする害虫忌避材により、上記課題を解決した。特に、該溶液が、天然由来成分として、（Ａ）環式モノテルペンアルコール及び／又は（Ｂ）環式モノテルペンケトンを含有し、かつ、（Ｃ）環式セスキテルペンを含有する溶液であると、上記課題の解決のために好ましい。【選択図】なし
