Fly Eliminators™ are tiny beneficial insects that kill flies by parasitizing them in the pupal (cocoon) stage, before they can hatch into annoying adult flies-the sensible alternative to pesticides. Used by dairies, feedlots and livestock facilities, they are affordable and easy to use. Reduce irritation, disease, stress and painful bites to your herd. This year get ahead of the flies!
