Insect repellant barrier

Abstract

An elongate insect repellant barrier for application to the exterior of a building. The barrier is formed of a backing extending in a substantially vertical direction when applied to the exterior of a building, a bottom surface extending from the backing, and a lip formed along the front edge thereof. The backing, bottom surface and lip form a trough along the length of the barrier, and an upper angled surface slopes downwardly from the backing and extends outwardly from the backing to overhang the lip along the length of the elongate barrier. The trough is filled with a mixture of mineral oil, or other light oil, and water, from which crawling insects attempting to enter the building fall as they reach the top of the lip on the front edge of the elongate member and are unlikely to escape, and the overhanging angled surface protects the oil and water mixture in the trough from being affected by ambient weather conditions.

1 . An insect repellant barrier adapted for application to a building or other structure comprising:
 an elongate backing extending in a substantially vertical direction when said applied to the exterior of a building;   a bottom surface extending from said backing and having a lip formed along the front edge thereof, said backing, bottom surface and lip forming a trough along the length of said elongate backing; and   an upper angled surface sloped downwardly from said backing and extending outwardly from said backing to overhang said lip along the length of said elongate backing.   
   
   
       2 . The insect repellant barrier of  claim 1  additionally comprising an oil-water mixture contained within the trough. 
   
   
       3 . The insect repellant barrier of  claim 1  wherein said upper angled surface additionally comprises a front edge extending along the length thereof. 
   
   
       4 . The insect repellant barrier of  claim 1  wherein said elongate backing is applied to the exterior of a building by an adhesive that seals between said backing and the exterior of the building. 
   
   
       5 . The insect repellant barrier of  claim 1  wherein said elongate backing is substantially level when applied to the exterior of the building.
