This is my second flea/tick/mosquito season in central Indiana. Last year the boys were flea free and only 1 half dead tick on one of them after camping in southern Indiana. I have them on granulated garlic last year and used an essential oil spray on them. I was wondering of course if I just got lucky and thought I would try a flea prevention treat. It calls for a mixture of Brewers yeast and coconut oil. Has anyone tried this? Or has anyone heard this recipe was successful. I will use what I used last year I just thought if any added protection couldn't hurt. I absolutely despise fleas ?
