PROBLEM TO BE SOLVED: To enable an insect repellent agent to be stored without bringing it into contact with a human body while securing high volatilization of the insect repellent agent.SOLUTION: In an insect-proof tool which includes a cradle 4 formed with a spiral groove 3 on the upper surface and an insect repellent agent 5 accommodated in the spiral groove 3 of the cradle 4, the cradle 4 is of a spiral shape roughly similar to the spiral groove 3, and includes a bottom wall 4A at the bottom of the spiral groove 3 where the insect repellent agent 5 is placed, and side walls 4B erected on two sides of the spiral groove 3 on the bottom wall 4A. The height of the two side walls 4B is made higher than the top face of the accommodated insect repellent agent 5.SELECTED DRAWING: Figure 1【課題】虫忌避薬剤の高揮散を確保しながら人手にも触れさせずに収納しておくことができるようにする。【解決手段】上面に渦巻き形状の溝３を形成した受け台４と、この受け台４の渦巻き溝３に虫忌避薬剤５を収納した防虫具であって、前記受け台４は、渦巻き溝３と略相似形の渦巻き形状であって、虫忌避薬剤５を載置する渦巻き溝３の底の底壁４Ａと、この底壁４Ａ上の渦巻き溝３の両側に立設する側壁４Ｂとを有し、両側壁４Ｂの高さを収納する虫忌避薬剤５の上面より高くしている。【選択図】図１
