Fly parasites prevent adult flies from hatching. These tiny beneficial insects kill the pupae and then use the killed pupae as “nurseries” to grow new parasites. Stop Fly Breeding with Fly Parasites Release throughout the fly season every week or every other week. See the recommended release schedules below. Place the Fly Parasites near manure piles, in stalls and areas of the paddock where horses tend to congregate and areas where moisture encourages maggots to appear. Shortly after the maggots form pupae, the Fly Parasites will attack them. Fly Parasite Schedules (shipping cost included) Order by June 10
