The flies can be seen on the glue board behind the Flyweb Fly Light when a large amount has been caught. One way to make the flies less noticeable is to choose the black glue boards for the unit rather than the white, as they will blend in and not be so obvious to passers by. Please let us know if you have any other questions.
