Killing flies by suspending, in a fly-infested area, a strip of paper or the like which has holes in it, and which has an obverse surface colored with luminescent material overprinted with pictorial illustrations of clusters of flies in postures which arouse the curiosity of other flies, the pictorial illustrations and the luminescent coating on the strip being intervened by white fields of substantially similar perimetrical contour as the flies in the pictorial illustrations; and the obverse surface of said strip carries fly food-toxin which may also be colored with luminescent material.
