I've noticed swarms of tiny flying bugs in my chicken coop the last couple of days. These bugs crawl over the faces of my chickens and rabbits. I stuck some to tape and looking at them under a magnifying glass discovered they have wings and appear to be flies. Further research showed Thailand (where I live) now has a new species of very tiny fly. Just my luck! Still battling malaria carrying mosquitoes, and now this! Can anyone please tell me the very best way to get rid of these miniscule flies (the size of this period .). All help appreciated.
