Often mistaken for common houseflies, cluster flies emerge from winter dormancy and gather in large numbers at sunny windows. Placed in a lower corner of any window where they congregate, this simple non-toxic trap can capture as many as 1000 before requiring disposal.

Instead of using an attractant, the trap takes advantage of the fly's natural behavior; once it contacts the window pane, the fly instinctively descends into the corner, where the trap lies in its path. Entering through a slot in the top of the trap, it becomes coated with an extremely fine, natural powder derived from ground eggshells, which renders it unable to escape.

The 9 3/4" × 3" × 1 3/4" trap mounts using two removable peel-and-stick adhesive strips. For best results, place one trap in each window where you observe cluster flies.

Made in Canada.
