PROBLEM TO BE SOLVED: To obtain an insect-proofing material enabling the use of a waste such as paper powder, an extraction residue of coffee extract or used tea leaves as a support of an insect-proofing agent, especially transpirable empenthrin, having little bulkiness and useful for wool or the like. SOLUTION: This granular insect-proofing material is obtained by compounding at least one kind of waste selected from wastes such as an extraction residue of coffee extract, used tea leaves and paper powder, a highly water- absorbing resin in an amount less than the amount of the selected waste and an insect-proofing agent, and forming them into granules. Further, the granular insect-proofing material is produced by forming granules using a granulating part containing at least one kind of waste selected from wastes such as an extraction residue of coffee extract, used tea leaves and paper powder, and a highly water-absorbing resin in an amount less than the amount of the selected waste, and a coating layer part covering the surface of the granulating part and containing an insect-proofing agent. Further, an insect-proofing agent is further added to the granulating part, and the granular insect-proofing material can be prepared. |
