There is no vaccine to prevent filariasis, but controlling the populations of
blood-sucking insects, especially mosquitoes, can limit the spread of the
disease. In some areas where filariasis is common, people are treated yearly
with preventive medicine to kill any immature worms in their blood. To
protect themselves, people can also do the following:

• Stay inside as much as possible from dusk to dawn, when mosquitoes
  are most active.
  
• Sleep under mosquito netting.
  
• Place screens in all windows.
  
• Use insecticides around living areas.
  
• Apply insect repellent to exposed skin.
