Prevention and control

The oil-based mosquito repellents, which are effective against mosquitoes, are also effective against midges. Thoroughly apply the repellent – the midges can find even a small spot of untreated skin. The effect of the treatment is brief (a few hours).

Draining or flooding of larval breeding sites as well as spraying the breeding sites with pesticides are control methods that have been used in other countries than Denmark. These methods are not applicable under Danish conditions. Midge nuisance is sometimes caused by the discharge of waste water with a high content of organic matter. Here, terminating the discharge will solve the problem.
