One of three ingredients in our patented, stinky, flies-love-it formula. Ammonium Carbonate can be mixed with Active Dry Yeast and water to create a brew that flies can't resist.
While any substantially stinky bait will work in our fly traps, we have found this combination to be highly effective. Our Fly Trap Replacement Bait is comprised of 1 oz. Ammonium Carbonate and 2 lb. Active Dry yeast. Add water to this mix and this bait is ready to attract flies for up to three months.
We offer a Fly Trap Replacement Bait with everything you need to attract those flies (just add water).
