Abstract
The system and method for preventing the passage of crawling insects upon the exterior surface of an object includes a member having an inner surface, adapted to be disposed adjacent to the exterior surface of the object, an opposed outer surface that has a low coefficient of friction for preventing the insects from traversing the outer surface since the crawling insects are unable to obtain sufficient traction with the outer surface of the member, a means for affixing the member to the exterior surface of the object so that the insects are forced to attempt to traverse the outer surface of the member in order to reach the exterior surface of the object above the member.
Claims12
An insect barrier system to prevent the passage of crawling insects upon the exterior surface of an object comprising:
- (a) a member having an inner surface and an opposed outer surface, the inner surface of the member being adapted to be disposed adjacent to the exterior surface of the object, the outer surface having a low coefficient of friction for preventing said crawling insects from obtaining sufficient traction therewith to cross said outer surface;
- wherein said outer surface of the member is a non-fluorinated polymer selected from the group consisting of polyethylene terephthalate, polyvinyl chloride, polyethylene, and polypropylene, wherein said outer surface has a coefficient of friction from about 0.05-μ0.45μ;
- and
- (b) means for affixing the member to the exterior surface of the object.
A method for at least reducing access of crawling insects to an object comprising
- applying to an object a length of a member having an inner surface and an opposed outer surface, the inner surface being adapted to be disposed adjacent to the exterior surface of the object, the outer surface of the member having a low coefficient of friction to prevent insects from grasping the outer surface of the member and traversing the outer surface of said member;
- wherein said outer surface of said member is a polymer selected from the group consisting of polyethylene terephthalate, polyvinyl chloride, polyethylene, and polypropylene wherein said outer surface has a coefficient of friction from about 0.05-μ0.45μ.
