Actually there is away to use this for ankle biters on the boat. I take the cardboard tube from a paper towel roll and paint them yellow, then wrap a fly strip around them. I then slide the tube over my boat seat pedestal, I am lucky enough that it fits perfectly. When I am done fishing for the day the whole mess just slides off and goes in the garbage. I got the idea using the yellow boards in the green house that we use for bug control. I might have to try some purple ones though. Total cost is about a quarter.
Just search Lakeiwanttobethere to find where Bobby has his cabin!
