The fly paper that I usually see for sale comes in rolls that are ugly and
messy to use, but I once bought some clear fly paper that I can no longer
find for sale. It was a clear plastic sheet with clear goo making it hardly
noticeable and it had a thin sticky strip so that it could be stuck on a
window (bugs were then attracted by the light rather than the color). It was
great for catching the occasional housefly and for controlling and
monitoring fungus gnats.

Does anyone know where I can buy this?
