Flies cause great discomfort to many animals.They torture the animals by biting and can cause allergic skin conditions, especially in horses, where fly bite allergy is the most common skin disease found. Flies irritate the animals’ eyes, which can cause serious infections. They are attracted to wounds, again complicating them with infection. Flies carry contagious diseases from one animal to others. As an example, again using horses, they can easily transmit a cold, flu or strangles. The answer to the pest problem is not larger quantities of pesticides, it is preventing the flies’ reproduction. This can be accomplished by Ecological Fly Control and manure management. Fly Parasites are very easy to use. They are shipped in their pupal stage packed in clean pine shavings to insulate and protect them during shipment. Releases are usually done when the first of these adults begin to emerge and involves nothing more than sprinkling the pupal casings in and around the areas of fly breeding. Once released, each insect will then kill 40–50 flies, and in a period of two to three weeks another generation of beneficial insects is born. Fly parasites are not able to use anything but flies in order to have offspring. They do not bite, sting, nest or swarm and will not become a nuisance to livestock. And because they are nocturnal, these extremely small insects are rarely seen during daylight hours unless one searches carefully in areas where flies are breeding. When fly parasites are introduced early and a sufficient population maintained through the fly season, the flies are unable to increase their numbers. To gain and maintain control of your fly problem is easy and affordable.

Effective fly control has long been an elusive goal of man. Since World War II chemical agents have been the primary weapons. Now, increased resistance of fly populations to these chemicals, widespread ecological damage and prohibitive costs necessitate other methods. The use of pesticides over the past decades has created insecticide resistant flies. In many cases, flies can now resist a pesticide dose 10 times as concentrated as just a few years ago. It has long been known that there are many insects that are beneficial to man. A tiny insect called the fly parasite can help control those flies which create such a nuisance around livestock. Fly parasites are beneficial insects that lay their eggs in the immature stage of the fly known as the pupa stage. The developing fly parasite consumes the fly as food and serves as an important preventative measure, since a female fly killed in this way is kept from laying up to 900 eggs later on as an adult. Fly parasites are natural enemies of flies, and there are species present throughout the world, wherever flies breed. In the United States, several different species have been found and studied extensively to determine their effectiveness in fly control. Several species have been identified in reports from the USDA and independent researchers. Shipped to the customer in the form of parasitized fly pupae, the insects are easily handled as they are still developing within the fly pupa they are consuming. Once their growth cycle has been completed, they cut a hole in the pupal casing, and then leave as adults to search out and parasitize more flies.
