NCDHD’s Environmental Health program tracks dead birds and helps with testing mosquitoes to monitor West Nile Virus in our 9 county district. Mosquito pools are tested in O’Neill and Valentine area.

West Nile Virus is contracted through mosquitoes that have been bitten by an infected bird. Generally birds cannot pass the virus to humans.  West Nile Virus symptoms are flu-like and can include a slight fever or headache. Severe symptoms are not likely, but can lead to encephalitis, which can cause inflammation of the brain, disorientation, convulsions and paralysis. People over 50, infants, and pregnant women are especially susceptible to this disease.

Mosquitoes in Nebraska

There are approximately 50 different species of mosquitoes living in Nebraska but only about half of them spread disease to humans.

Male and female mosquitoes feed on plant nectar but the female mosquito requires a blood meal to produce eggs. A female mosquito breeds in the presence of water and lays eggs after obtaining a blood meal. Where the female mosquito chooses to lay her eggs depends on the larval habitat preference.


The 50 mosquito species native to Nebraska can be organized into four groups based on their larval habitat preferences: permanent pool, transient water, floodwater, and artificial container and tree-container.

  1. Dress your child in clothing that covers arms and legs.

  2. Cover strollers and baby carriers with mosquito netting.

  3. When using insect repellent on your child:

    • Be sure to follow label instructions​

    • ADULTS: Spray the insect repellent onto your hands and then apply to your child'd face being sure to avoid EYES, MOUTH, HANDS, OPEN AREAS, OR IRRITATED SKIN


      • Oil of Lemon Eucalyptus (OLE)​

      • Para-menthane-diol (PMD)
