    Bug Check is rated 4.1 out of 5 by 278.
    Rated 1 out of 5 by from Beware - Ingredients misrepresented Just received a 30# bag today. The first thing I noticed was the ingredient list on the bag doesn't match what SmartPak listed for ingredients. Instead of dried grape seed as the primary ingredient, it's actually brewers dried yeast, a much cheaper ingredient with fewer health benefits. Had I known the ingredients had been downgraded and cheapened, I would not have purchased this product. Very disappointing.

    Rated 4 out of 5 by from Seems to help deflect the flies, horseflies Ordered this on the recommendation of a friend, one horse ate it mixed with feed, one, not so much, so now we mix it with soaked alfalfa pellets. Stable/houseflies and horseflies seem less bothersome, but the biting kind of cattle flies don't seem phased by it. Will continue to buy but also use fly sheets, spray and fly boots.
