Vi utvecklar metoder för miljömässigt balaserad kontroll av myggproblem

The aim of Biological Mosquito Control is

to reduce the abundance of floodwater mosquitoes to acceptable levels so that people can enjoy living in and visiting the Nedre Dalälven region.

Update on the Application Process

The Nedre Dalälven application process is at the stage where the Swedish Environmental Protection Agency has now forwarded our request on to the central government (read here, Swedish only). Regarding Forshaga, our opinion on the stakeholder response to our application has been submitted to the Swedish EPA (read here, Swedish only). Following their review, we expect that our request for mosquito control with Forshaga will also be forwarded on to the central government. Read more

The application has been submitted to the Swedish Environmental Protection Agency

On October 15, the application to suppress mosquitoes along the Nedre Dalälven was submitted. The application requests permissino for 3 years (2020-2022) as opposed to the previous one year permits. Our hope is that by submitting this early and for multiple years, we can alleviate any delays between receiving the permit and potential early spring floods. This application encompasses a total of 12 543 ha (see proposed areas here). An application for control in Forshaga municipality for 2020 and a total of 669.4 ha (see areas here) was sent to the Swedish Environmental Protection Agency on October 24. On the Swedish Environmental Protection Agency's website, the entire application for Nedre Dalälven is available here, the entire application for Forshaga is here.


Week 6

We have sent the Environmental Department (Miljödepartment) a response to the recommendations that the Swedish Environmental Protection Agency (Naturvårdsverket) had made on our application in Nedre Dalälven.

Week 7

Our response to recommendations from Naturvårdsverket are prepared for our Forshaga application and will be sent to the Miljödepartment this week. 

Week 8

Agreement letters to new property owners and renewals of existing properties within the mosquito control areas are going out.


There are around 50 species of mosquitoes in Sweden and we have found 33 species in the area around River Dalälven.

Mosquito control

Larvae of floodwater mosquitoes are controlled by aerial application of VectoBac G granules, which contain Bti as active ingredient and are dispersed by helicopter.

Non-target programme

To study the potential environmental impact of Bti, we have a non-target organism  programme.
