Flame, yes, I have 2 for the hatchery pond, and have had mixed results. I do put them on long paracord because I want them moving with the wind. They seem to work for a while, but eventually the GBH get used to them. If they're roosting on the tires, then get chicken wire from any farm or big box store, crumple 5-10 feet up, and tie them to the top of the tires. The higher it is, the better.
I'd stay away from traps, especially at pond banks.
