Vision and Values

Miljøfluen® produces predatory flies (Black dump flies) and mini wasps to fight stable flies in agriculture. Both can be applied in conventional as well as ecological farms.

Our vision

​Miljøfluen® aims to be Agriculture’s leading cooperation partner within fly control. Thus we have bulid our concept upon a series of values to obtain that goal.

1. You deserve a cost-effective solution to stable fly problems

  • The price for our products is below what you normally pay for chemicals (biocides)

2. You deserve an easy solution

  • ​First of all we look into which type of product suits your stables the best: predatory flies, miniwasps or maybe a combination of both
  • Next, Miljøfluen® send you the product by mail
  • You receive the parcel, take out the product and put the bags with predatory flies into the supplied buckets (containers) or place the buckets with mini wasps near the straw and manure of the stable.
  • Leave the predatory flies as well as the mini wasps to do their work
  • In a few weeks - just add new predatory flies or mini wasps
  • Miljøfluen® will naturally tell you when it is time for you to add useful insects again - we will automatically send you the product

3. You deserve quality products from Miljøfluen®

  • Our predatory flies are SPF approved
  • Every year a veterinarian visits our company and controls our production facilities and assess the risk of contamination
  • Our predatory flies are packed in perforated bags which are weighed by a packing machine. Thereby we always achieve equal size of the product in each bag

4. You deserve an evironmentally friendly choice

  • The useful insects are so effective that it is often not necessary to use chemicals (biocides)
  • Thus you achieve an environmentally friendly solution to a daily problem in many stables, and you avoid using unnecessary chemicals

5. You deserve flexibility in meeting your needs

  • If your circumstances change, we are ready to change your agreement
  • Should you expand your farm, get more stables, or stop having animals, you just need to contact us. We change your agreement so that you get exactly the number of bags with predatory flies or buckets with mini wasp that you need
  • An agreement with Miljøfluen® is without ties which means that you can always terminate our agreement without any notice of termination

6. You shold benefit from our knowledge in the field

  • Since the company was founded in 1993, we have experimented with our breeding methods in an effort to achieve the best possible breeding of predatory flies and mini wasps. We continue to do so
  • We gain new knowledge about stable conditions and animal husbandry by cooperating with various companies and authorities
  • Based on our experience from stable visits, we adjust and refine our predatory flies and mini wasp insertion programs on a regular basis
  • We participate in research collaborations on further development of the use methods of the predatory flies and mini wasps

7. You deserve good costumer service if you need us

  • You can contact Miljøfluen® in several ways for example directly at main office by e-mail or by telephone +45 98 25 99 00 at daytime
  • You will most often as a customer have a consultant that you can contact for changes or questions

About Miljøfluen

In 1993, Miljøfluen® established production of predatory flies and mini wasps to control stable flies in Danish farms. 

Predatory flies and mini wasps are naturally existing in Danish and most of European nature and by means of the way they act and live, they reduce the annoying stable flies.​
