Abstract
A snail and slug control apparatus formed as a composite sheet fabricated from a layer of polythene (polyeethylene) coated at least on one side with copper foil. An adhesive layer may be applied between the layer of polythene and the copper foil. The apparatus may be fabricated into a composite sheet by inserting the layers between nip rollers and cut to a preselected width. A length of the apparatus may be shaped to form a protective perimeter around selected areas. The apparatus may be held in place with stakes.
Claims2
An apparatus to form a protective border against snails and slugs comprising in combination:
- a copper foil of preselected thickness having a selected first side;
- a layer of copper in rough-up configuration applied to said first side;
- a thin layer of non-soluble zinc applied to said rough-up copper;
- an adhesive layer applied to said first side of said copper foil;
- and
- a sheet of a preselected polythene material applied to said adhesive to form a flexible laminate and fabricated by pressing said layers and sheet between a chill roller and a nip roller to form a composite sheet of preselected thickness.
