I can't wait to try this, I thought I was the only one with this problem.
WOW...it is indeed a recipe and it worked wonders in my backyard! Thank you so much for posting this! We can actually go outside again without the terrible smell and the flies seem to have vanished as well!
Boy do I need this stuff! Thanks for having the courage to post it! I'll make it up in the next few days and get back to you!!!!
