DE did not work against the flies for me & is all expensive hype.
I live in the hot, humid South and flies can be bad. I ordered the gnat-size, fly larvae eating WASP from http://www.arbico-organics.com/fly-control-program.html and my fly problem has disappeared.
I don't even get that many in my solar fly trap anymore.
