I guess they flock to warm surfaces in the fall, prefer white colored buildings on the sunny side of the building. I do wonder if someone could put white styrofoam or PVC decoys of some type in the pond and encourage the swarm to the pond and let the fish pick them off? Maybe a decoy plus a suction fan that blows them into the water like other commercial insect feeders available for pond owners?
I can't imagine a fish could taste the bug enough to choose not to eat them, especially if they were trained to snap things off the surface already (via a feeder or bug light)?
Where do the swarms go at night? Glad that we don't seem to have a problem with these in our area. Stink bugs are bad enough
