Fly Eliminators® - Biological Fly Control

What are Fly Eliminators?

Fly Eliminator Life Cycle

Fly Eliminators are gnat-sized parasitic wasps used for biological fly control in livestock facilities, on farms, near food production areas and around homes. They specifically target developing (pupal) stages of manure breeding flies. Female Fly Eliminators seek out their target host – usually near decomposing organic material – where they deposit their eggs inside the fly pupae. These eggs hatch and feed on the developing flies, stopping adult pest flies from hatching.

Once mature, Fly Eliminators emerge from the fly pupae to look for a mate after which the females lay more eggs. Fly Eliminators reproduce in approximately 4 weeks, constantly replenishing the beneficial insect population. Pest flies reproduce at a faster rate than Fly Eliminators; therefore, they must be reintroduced on a regular basis.

We recommend releasing shipments of Fly Eliminators every 3 to 4 weeks throughout the duration of the fly season. In some cases, weekly or bi-weekly releases may be necessary. If you have questions about quantity and frequency of application, please call us so we can answer them. The fly zone map below will help you estimate your program's start date and duration. You may also contact our experienced staff to tailor a program that fits your particular needs.

What You Get:

We ship Fly Eliminators as parasitized fly pupae in wood shavings. When received, check for evidence of hatching. Once a few have hatched, they are ready for release. Simply disperse small handfuls or scoops around your property into "hot spot" breeding areas: near manure piles, under water troughs, below bedding, corners of pens and paddocks, and feeding sites. Cover with dirt to protect pupae.

Fly Eliminators are vital to an integrated fly control program and should be combined with manure management and trapping. We encourage our customer to stay in touch through the fly season, so programs can be adjusted if necessary.
