<p>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.</p> |
