Mollusk barrier

1. A barrier for deterring gastropod mollusks from entering an area, the barrier comprising:

(a) an elongate tubular support comprising a plastically deformable core member and an outer sheath disposed radially outwardly from the core member and extending from a proximal end of the outer sheath to a distal end of the outer sheath, wherein the outer sheath has at least one opening at an intermediate location between the proximal end and the distal end that exposes the core member;

(b) a first barrier end and a second barrier end, the first and second barrier ends being releasably connectable;

(c) a plurality of outwardly extending projections attached to the tubular support, the projections spaced circumferentially and longitudinally along the tubular support to define the barrier, wherein the projections are attached to the tubular support in a location different from the at least one opening; and

(d) at least one outwardly extending spike attached to the tubular support, wherein the at least one spike is configured for insertion into a substrate to position the barrier in a desired location.

2. The barrier of claim 1 , wherein the plastically deformable core member is a metal wire.

3. The barrier of claim 1 , wherein the plastically deformable core member is a copper wire.

4. The barrier of claim 1 , wherein the outer sheath is polypropylene.

5. A method for deterring gastropod mollusks from entering an area, the method comprising:

(a) positioning a barrier along the perimeter of the area, wherein the barrier comprises:

(i) an elongate tubular support comprising a plastically deformable core member and an outer sheath disposed radially outwardly from the core member and extending from a proximal end of the outer sheath to a distal end of the outer sheath, wherein the outer sheath has at least one opening at an intermediate location between the proximal end and the distal end that exposes the core member;

(ii) a first barrier end and a second barrier end, the first and second barrier ends being releasably connectable;

(iii) a plurality of outwardly extending projections attached to the tubular support, the projections spaced circumferentially and longitudinally along the tubular support to define the barrier, wherein the projections are attached to the tubular support in a location different from the at least one opening; and

(iv) at least one outwardly extending spike attached to the tubular support, wherein the at least one spike is configured for insertion into a substrate to position the barrier in a desired location.

6. The method of claim 5 , wherein the plastically deformable core member is a metal wire.

7. The method of claim 5 , wherein the plastically deformable core member is a copper wire.

8. The method of claim 5 , wherein the outer sheath is polypropylene.
