Controlling Culicoides in the Environment

In Northern Europe the control of Culicoides has previously been neglected as they were not significant vectors of disease before the arrival of BTV-8. Effective Culicoides control requires control in the habitat of the midges as well as control on affected animals.

Modification of the breeding habitat

Culicoides midges breed in moist conditions in a variety of habitats, particularly damp, muddy areas and in faecal and plant matter. Modification of these areas by removing organic matter and draining muddy areas, form an important part of the control strategy for Culicoides.

filled pond

The breeding habitat has been modified by draining and filling the pond. The area is no longer suitable for Culicoides midges to breed in.

The use of laravcides in possible breeding grounds and environmental control with adulticides are also used.

Control in buildings can also be with the use of :

  • Fly traps
  • Spray-on method (Butox EC)
  • Scatter baits
  • Paint-on method
  • Mists
