Fly problems in animal husbandry

Feedlots and other sites of intensive animal husbandry are particularly susceptible to nuisance fly populations. House flies (Musca domestica) and stable flies generally breed within feedlots, in drains, sedimentation basins, silage pits, spilt feed and areas of undisturbed manure.

These flies cause significant annoyance to livestock, staff and neighbours and can carry disease.
By using fly parasites in your stables you are able to control the population of house and stable
flies in an easy and effective way.

Historically chemicals have been used to control nuisance flies. Increasing problems with resistance to pesticides and the threat of residue in meat and milk products have led to a worldwide trend towards more ecologically sustainable control methods. We encourage farmers to adopt an integrated pest management (IPM) approach to nuisance fly control. Good sanitation impedes fly breeding and assists the establishment of natural enemies including the parasitic wasps.

Fly breeding substrates such as manure, spilt feed and vegetation should be removed or kept dry.

Parasetic Wasps:
Biological control – an ingenious solution to the fly problem

In stable systems with straw/manure systems (by pigs, cattle, sheep, poultry, horses etc.) it is possible to control the house and stable flies with Parasetic Wasps. They are fly parasites and natural enemy of most house and stable flies and live in the same environment as the house and stable flies. The Parasetic Wasps reproduce by laying their eggs in the pupa of the house and stable flies. This fly parasite process kills the stable flies before they hatch.

Parasetic Wasps - Just what are they ?

Parasetic Wasps are really just tiny flies, 2 to 3 mm long. They do not bite or sting and never become a pest themselves. They live their entire life on or near manure piles or decaying organic matter and live solely on house and stable fly pupa or larve. Parasetic Wasps go unnoticed within the environment. They are harmless to other insects than house and stable flies and to all vertebrate animals including humans.

How to use Parasetic Wasps ?

Parasetic Wasps are easy to use, the farmers simply dump them on the manure every 2 weeks.
We recommend spreading them around on several locations on manure where you see aproblem. The parasetic wasps will generally not travel from location to location so you may need to establish several different colonies.
The Parasetic Wasp can be used in all kinds of systems with manure, that is in horse, cattle, pig, sheep and poultry production.

How effective are the Parasetic Wasps ?

The Danish Department of Agriculture has reported results of how well the parasetic wasps control fly populations in different studies: One study concluded that the wasps suppressed a population of house/stable flies in about 30 days. Our customers who uses parasetic wasps report them as very effective and it is at the same time also a very easy way to control flies.

We help the farmers to determine the dose of wasps they need based on not only the number and type of animals they have but also the size of the feedlot, pasture or stable and the conditions in their area. We calculate the needed amount of wasps for each farm and make a delivery plan for the farmer. After receiving them by post it only takes a few minutes to put the boxes containing the wasps in the stable. We have found that it is best to establish a colony of the wasps rather than simply buying one or two thousand insects. This insures that the farmer has a viable number of wasps to survive the elements and still control the population.

If chemical treatment is required, some larvicides such as cyromazine are less harmful to parasitic wasps and often provide better control over an extended time. Larvicides generally tend to be less harmful to wasps and the environment. Granular baits and bait strips should also be used as part of an IPM (integrated pest management) approach to nuisance fly control.
