I have read a majority of the previous postings on this subject and did not find them satisfying. I live in Miami and the closest DE supplier is about 2 hours away. Florida seems to have monstrous swarms of these flies. My yard is no exception. I have 8 quail and 4 week old chickens and its a swamp of flies out there. How do I get rid of these things? I don't think an ordinary fly trap would work with this amount of flies.
