While the buffalo gnats are greatly diminished, I suspect that\'s due to the hatch nearing completion. I used the Mosquito Barrier mixed at 4 times the labeled instructions, as directed by the manufacturer, and sprayed the ground of the exterior, interior, and the netting itself, of a 10\' x 10\' First Up canopy with mosquito net walls. As soon as I sat up a grower cage and added chicks, a swarm of buffalo gnats formed outside of the downwind wall; they appeared to have been attracted to the scent of the chicks and not discouraged by the spray. The net walled canopy worked beautifully to protect the chicks.
Cooler weather accompanied by heavy rain and flash floods seems to have greatly reduced the buffalo gnat numbers; or else the hatch just naturally slowed. [Older locals told me the hatch usually lasts two to three weeks] For awhile my lawn and trees were completely lacking of any daytime birds................... it was kind of spooky. LOL Yesterday I saw alot of Jays, Cardinals, and Robins were back.
