PROBLEM TO BE SOLVED: To provide an insect-proof sheet that preferably exterminates or repels pests in fruit trees or vegetable gardens at low cost.SOLUTION: A non-permeable long sheet of a predetermined width is folded in the shape of bellows so that peaks and troughs in the width direction may continue alternately in the longitudinal direction, and thereby a bellows sheet is obtained. Also, the peaks are held down and broken lines are formed by double threads in the longitudinal direction of the bellows sheet. Adhesives are laminated over the whole length direction on one surface of a central area divided by the broken lines of the double threads. An insect-proof sheet is cut in a length corresponding to the length of a target place to thereby form sheet pieces, and is made to adhere to trunks of fruit trees and fences of vegetable gardens using the adhesives to thereby form fixing parts. In this way, the upper parts of the sheet pieces are horizontally bent by using the broken lines of the upper side of the sheet pieces fixed to the trunks and fences to thereby form umbrella parts, and the lower ends of the sheet pieces are bent in the upper direction by using the broken lines under the sheet pieces to thereby form drug parts, and then the drugs with insect killing or insect repelling effects are filled in the drug parts.COPYRIGHT: (C)2015,JPO&INPIT【課題】果樹、あるいは菜園の害虫を低コストで駆除あるいは忌避したい。【解決手段】所定幅の非透水性の長尺のシートを幅方向の山と谷が長手方向に交互に連続するように蛇腹状に折り込んで蛇腹シートを得、また、前記蛇腹シートの長手方向に2条、前記山を押さえ込んで折れ線を形成しておく。前記2条の折れ線で分割される中央の領域の一方の面に、長さ方向全体に渡って粘着剤を積層しておく。防虫シートを目的とする箇所の長さに対応した長さに切断してシート片となし、果樹の幹や、菜園のフェンスに前記粘着剤を利用して密着させて固定部とする。このように幹やフェンスに固定されたシート片の上側の折れ線を利用して、前記シート片の上部を水平に折り曲げて、傘部を形成し、シート片の下の折れ線を利用して、シート片の下端部を上方向に折り曲げて薬剤部を形成し、前記の薬剤部に殺虫あるいは忌虫効果のある薬剤を充填する。【選択図】図1
