About Fly Eliminators:

1 Unit of Fly Eliminators - Biological Fly Parasites

Fly Eliminators are gnat-sized, nocturnal, burrowing fly parasites that 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.

At night ARBICO's tiny parasites seek out the pupa of the fly. They make a tiny tear in the pupa to feed and the females deposit (oviposit) their eggs within the pupa. Those eggs hatch within the pupa and feed on the developing fly, eliminating the adult flies. Fly Eliminators are suitable alternatives to toxic chemical 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:

Begin your program when spring temperatures first arrive (after final frost date). It only takes three consecutive days of 40°F weather for the overwintering fly populations to start hatching and maturing. Each female fly will lay up to 1,000 eggs in her lifetime, so it is important to release the parasites as early in the fly season as possible. Released fly parasites begin parasitizing the overwintering fly pupae immediately after hatching. Consider using fly traps and repellent sprays in conjunction with Fly Eliminators for best results if you typically have a severe fly problem.

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. Your next door neighbor just brought home 10 calves and they are 50 ft. from your back door.

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. For example, if you have a dairy or poultry facility, you may need to reduce the time between shipments for successful fly control. Please call us to speak with one of our knowledgeable fly control consultants and customize your Fly Eliminators program.

Life Cycle of the Fly:

The fly lays an egg that looks like a speck of sugar. Within a short time, literally hours, the egg develops into a larva that we call a maggot. Newly hatched maggots are microscopic and so small they are almost impossible to see. The maggots are light sensitive and move deep into the ground or manure away from the outdoor light. Once buried, they feed and grow until reaching a certain size when they pupate. This is the cocoon stage of the fly, which are brown pods about the size and shape of a piece of rice.

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.

Fly Control Zone Map

Begin with the zone for the state you are in. Dates shown on the map indicate suggested start and end dates for Fly Eliminator shipments. You may want to shift a zone if your elevation or microclimate is unusual. You can start anytime during the fly season.

Choose "Year Round" for climates that have flies all year and start now.
