A visual attractant for attracting a target insect include a substrate having a pixelated pattern portion defined by a plurality of blocks having a characteristic dimension that is within an order of magnitude of the size of the target insect. The plurality of blocks are colored to be highly reflective in a wavelength range selected to attract the target insect. A background portion is lighter in color than the pixelated pattern, to contrast sharply therewith. The blocks are clustered on the substrate such that most of the plurality of blocks define one or more irregular elongate streaks on the substrate. The pixelated pattern may be applied to a strip or to a pillar device, which may be adhesive.
