West Nile Virus is a disease carried by mosquitoes.  It can cause serious illness in humans and may even be fatal.

To protect our community we are asking residents to help reduce the mosquito population. Here are some things you can do:
Remove from around your home and neighborhood anything that might hold standing water. For example: old tires, buckets and wheelbarrows.
Report any standing water that you cannot remove.
UPDATED information on reporting dead birds.
Protect yourself from mosquito bites.

By following the links on the left you will find more detailed information on all these topics.

The female mosquito lays the eggs directly on water or on moist substrates that may be flooded with water. The egg later hatches into the larva, the elongated aquatic stage most commonly observed as it swims in the water. The larva transforms into the pupa where internal changes occur and the adult mosquito takes form. After two days to a week in the pupal stage, the adult mosquito emerges onto the water's surface and flies away. Only the female mosquito takes blood which they usually require for her eggs to develop.     West Nile Virus (for children) Learn how West Nile Virus was discovered, check out Operation: Infection Detection (CDC) West Nile Virus: Questions and Answers (CDC) Test your West Nile Virus Smarts (CDC)
