History of Miljøfluen®

Miljøfluen® is a family-run business located in North Jutland. Back in 1993, the company began to propagate predatory flies, also known as environmental flies, black dump flies, slurry flies or bio flies) to control house flies (Musca domestica) in the stables of farmers.

Early 1990s - biological fly control is new to Denmark

In the beginning, our production conditions were small and experimental. The use of the characteristics of utility animals to fight flies had not previously been common in Denmark. Until then, many farms had either lived with the fly plague in the stables or tried to combat them with insecticides (biocides). It was often hard work to fight flies and not comfortable for animals or humans.

Quite early on, in addition to the predatory flies, we also started producing mini wasps that were suitable for not only fighting house flies – but also biting house flies (Stomoxys calcitrans), in stables with deep bedding.

Late 1990s - the demand for predatory flies increases

In the late 1990s, a small but growing clientele began to demand other and easier solutions to fly problems and the Miljøfluen® therefore began to propagate the predatory flies in large quantities and send them off by mail to the farmer. We made a lot of experience – both about the predatory flies and what it takes to get them to live and grow healthy so that they can get out into the stable and do a good job – but also about stable conditions and the differences that can exist between pig and cattle stables.

2000s - farmers grew and we grew with them

Over the years the production of Miljøfluen® grew bigger and bigger. The established agriculture gradually became aware of the good characteristics of the predatory flies and demanded more and more deliveries. That is why we have expanded production facilities several times.

2010s - we move our production facilities to Dronninglund

In 2010 we moved to our current facilities in Dronninglund and by 2019 have expanded our premises again to keep up with demand for our products.

Over time, we have gained a great deal of experience and have gained great knowledge in the use of utility animals such as fly control, but we do not rest on our laurels. Danish agriculture is constantly changing and new technological solutions and expansions abroad have meant that we constantly have to be on our toes to keep up.

2020s and onward

We are proud to be part of Miljøfluen® and at the same time enjoy the ongoing process in continuing to produce good, healthy predatory flies and mini wasps that solve fly problems in stables in Denmark, the Nordic countries and Europe.

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.​
