Fly Parasites

Fly Predator Parasites are safe for people and animals. They are gnat sized, nocturnal, burrowing insects that do not bite, sting, or become a nuisance. This little bug is so effective because it kills the flies before they reach the adult stage.  The female Fly Predator Parasite will lay her eggs inside the fly egg, and use it for nutrients.  The flies will not hatch: instead more Fly Predators Parasites will hatch.

Start releasing these Predator Parasites when temperatures in your area are starting to warm.  For best results, release a batch of Fly Predator Parasites each month of the fly season.  The Fly Parasites will move around in search of fly eggs, and will even burrow on a breeding site.

To apply:  scratch about 1/2 inch hole in the ground, and simply sprinkle them out of the bag into the hole.  Cover them with dirt, or manure to protect them from wind, birds, and hot sun.  Release in several areas where flies are breeding.  Fly Parasites can also be hung in open bags on barn walls, and loafing sheds.
