sMILE!
I just got back from observing the bugslugger for about fifteen minutes. I noted the following:
1. Approximately two-hundred flying insects from 3-8 mm were flying all about the unit.
2. All bugs flew directly into the light.
3. At least ninety percent of the forays into the light resulted in a successful exit, unharmed.
4. Bugs that exited the light repeatedly attempted to enter the unit.
5. When the bugs hit the whip they were never observed to die. They were lightly injured.
6. Forty to fifty insects were flailing on the water when I left.
7. Being the first calm night since installation I was not surprised that there were not yet any slurping fish.
I'll keep reporting.
