Natural Control of Nuisance Flies

Fly parasites are the orginal biological control of pest flies. The natural enemy of most pest flies including house flies, horn flies, face flies and stable flies. Naturally occurring fly parasites live in the same environment that pest flies commonly lay their eggs, manure piles, compost heaps or anywhere decaying organic matter is found. Fly parasites reproduce by laying their eggs in the pupa of the pest flies. This fly parasite process kills the pest flies before they hatch.

Fly Parasites - Just what are they?

Fly parasites are really just very tiny flies. They do not bite or sting and never become a pest themselves. The live their entire life on or near manure piles or decaying organic matter and live solely on pest fly pupa or larve. Fly parasites typically go unnoticed within the environment and offer you natural organic control of pest flies.

How effective are Fly Parasites?

The US Department of Agriculture has reported results of well how fly parasites control fly populations in two different studies. One study concluded that fly parasites surpressed a population of house flies in about 30 days. Another reported that a after 90 days all house flies and stable flies in a poultry barn had been completely eliminated.

Most people who have used fly parasites report them as very effective. A number of periodicals related to horse, cattle and poultry production have featured fly parasites as the organic way to control flies.

How many Fly Parasites do I need?

There are lots of different publications that will provide different numbers when helping you determine the number of fly parasite colonies that are needed. We have found that it is best to establish a colony of of fly parasites rather than simply buying one or two thousand insects. This insures that you have a viable number of fly parasites available to survive the elements and still control the population. The fly parasites we have available are shipped in colonies of 10,000 to 15,000 insects. This easily establishes enough insects to provide control of flies for hobby farm owners and small farms. For larger farms and feedlots investigating fly predators as a means of controlling pest flies we recommend that you contact us and we will work with you to determine the number of fly parasites that you need. We will help you determine the number of fly parasites needed based on the not only the number and type of animals that you have, but also the size of your feedlot, pasture or stable and the conditions in your area.

In any case we recommend that you plan several purchases of fly parasites to properly get them established. We recommend that you release parasites several times, first starting just after the last frost and finishing prior to the last frost. If you purchase fly parasites over time you will discover that you will maintain a residual colony that you may only need to supplement once a season.

How do you use Fly Parasites?

Fly parasites are easy to use, you simply dump them on your manure, compost or decaying material. Of course it is best to manage the decaying material. We recommend spreading them around on several locations on manure where you see a problem. Fly parasites will generally not travel from location to location so you many need to establish several different colonies. You can supplement the effectiveness by managing this decaying material well. Either keep manure in a pile where it gets too hot for many pest flies to reproduce or spread it thinnly so that it dries out, either method will help control pest flies.
