To provide a repellent for land mollusk such as a snail, a slug or the like capable of repelling semi-eternally without exerting adverse effects on a farm product, a pet and an environment.
The repellent 1 is formed by coating a pressure sensitive adhesive including an insecticide on a back of a copper foil 2, a releasing paper 4 is laminated as releasable on the foil through the pressure sensitive adhesive layer 4, forming multiple micro projections 5 in a forming density of 10-50/m2 on the surface 2a of the copper foil 2 by punching needles from the backside to thrust to the surface side, and then cutting into a tape having a proper width. The land mollusks avoid a group of the micro projections comprising micro projections 5 and impossible to crawl up across the tape.
