About Fly Eliminators:

Fly Eliminators are gnat-sized, nocturnal, burrowing fly parasites that parasitize and kill manure-breeding fly pupae (filth flies) to control adult flies. They do not bite, sting, or harm humans and animals. Larval control is one necessary step in a complete fly control program. Adaptable to all climates, these parasitic wasps develop within fly pupaes, killing the immature fly in the process. The adult Fly Eliminators' life span is dependent on temperature, but averages 3-4 weeks. Periodic releases of Fly Eliminators are recommended to keep up with the highly active female flies rapid egg laying. Expect a reduction in general fly population in four to six weeks.

Fly Eliminators are suitable alternatives to chemical fly sprays and broad spectrum insecticide use for prolonged fly control.

How To Order:

Use the pull-downs above to select the correct Fly Control Zone, number of animals, desired shipment frequency and total number of shipments you would like. Please specify if you would like to Pay-Per-Shipment in the "Special Instructions or Comments" box on the Shipping Information section of checkout. If the preset shipment dates are not to your liking, please indicate your preferred start date in the same "Special Instructions" or comments field.

When To Release Fly Eliminators:

Release when spring temperatures first arrive (after final frost date). It takes three consecutive days of 40°F weather for the overwintering fly populations to start hatching and maturing. Each female fly lays up to 1,000 eggs in her lifetime, so it is important to begin releasing the parasites early in the fly season. Released fly parasites begin parasitizing fly pupae immediately after hatching.

Continue releasing the Fly Eliminators throughout the entire fly season (until the first significant frost). It is important to release all recommended batches. The last batch may overwinter in warm climates, but should not be relied upon for fly control the following season.

Notify an ARBICO consultant if any of your conditions change, ie. you have more animals, ants are becoming a problem, or your neighbor just brought home more animals that may affect fly numbers.

Use Fly Eliminators in conjunction with EM-1 Microbial Inoculant to help break down organic matter along with good manure management.

Specialized or Custom Fly Control Programs:

If you don't see a program above that fits your needs we are happy to help you set up a custom program over the phone. Please call us to speak with one of our knowledgeable fly control consultants and customize your Fly Eliminators program. For example, if you have a dairy or poultry facility, you may need to increase the shipment frequency for successful fly control.

Pesticide Susceptibility:

Do not spray the treatment area at the same time you release the insects. If you must spray, we recommend that you spray 48 hours before or after releasing the parasites.
