Bug Check is an oral granule or pellet supplement designed to be top-dressed onto daily feed rations for horses, cattle, sheep and goats. Its formula combines garlic, brewers yeast, thiamine and grape seed pomace with diatomaceous earth, which passes through the digestive tract and into manure to interrupt fly development. Probiotic cultures, including saccharomyces cerevisiae, lactobacillus acidophilus and enterococcus faecium, are included to support a healthy gut environment. The supplement is non-toxic and formulated without synthetic chemical insecticides. It ships in a resealable container with an enclosed one-ounce scoop for measuring daily servings. No mixing or preparation beyond top-dressing onto feed is required.
