Learn how we track and control mosquitoes. Get tips for preventing bites and reducing breeding areas.
In summer, we watch certain mosquito breeding areas for mosquitoes that carry diseases that can make you sick.
Why are we concerned about mosquitoes?
Mosquitoes can spread diseases like West Nile Virus. The main mosquito species we track is the Culex mosquito. This species can cause West Nile Virus infection in humans.
What do we do to reduce numbers of mosquitoes that cause disease?
In addition to watching breeding areas, we trap adult mosquitoes to measure how many are in an area. Some of the mosquitoes are tested for West Nile Virus. If we find high numbers of the species that can spread West Nile Virus, we treat water on public lands to reduce the number of mosquitoes.
