Abstract: A method and system for trapping arthropods includes a base and a first wall coupled to the base. The base and the first wall define a fluid source retention area. The first wall has an exterior surface. The device also includes a second wall coupled to the base and surrounds the first wall. The second wall has an interior and exterior surface. The exterior surface of the second wall has a first texture, and the exterior surface of the first wall and interior surface of the second wall have a second texture. The first texture is more coarse than the second texture.

Abstract: A method and system for trapping arthropods including a base having a vertical axis, an outer wall coupled to the base and surrounding the axis, an inner wall coupled to the base and surrounding the axis, and a fluid source arranged to dispose the fluid between the outer wall and inner wall. The system may include an intermediate wall coupled to the base, the intermediate wall surrounding the axis and being disposed between the inner wall and the outer wall. The outer wall and the inner wall each have an interior and exterior surface, the interior surface of the inner wall and the exterior surface of the outer wall have a first texture, and the exterior surface of the inner wall and the interior surface of the outer wall have a second texture, the first texture being more coarse than the second texture.
