As far as concoctions go, I honestly can't pinpoint to many that I may use. I feed raw and do my garlic water regiment. I do make a decent paste out of tea tree oil and vaseline with aloe. It works pretty good to keep flies off their ears . I'll tell you something else I do speaking of flies.. I use the fly jars that you buy at tractor supply, rather than buy the fly attractant refills that they sale I take my chicken juice that is left after I use my leg quarters out of the bag and poor it in the traps mixed with a little water. After a day or two that stuff will draw more flies than the store bought stuff ever did! And it's free.
