Northwest Mosquito and Vector Control District

Northwest Mosquito and Vector Control District The Northwest Mosquito and Vector Control District provides vector control services in the northwest

The Northwest Mosquito Abatement District was formed on December 28, 1959 to control mosquitoes in the northwest portion of Riverside County encompassing 150 square miles. The population of the District at that time was approximately 50,000 residents. Since inception, the District has grown significantly in population and area. Additionally, the geographical landscape has changed dramatically, fro

m rural to mostly urban and suburban, thus creating a different set of vector problems. In 1968, upon request by the Board of Supervisors, the Board of Trustees adopted the additional responsibility of controlling biting gnats in areas adjacent to the Santa Ana River without additional revenues to the District. On August 16, 1993, the District added services to control all important vectors and changed its name to NORTHWEST MOSQUITO AND VECTOR CONTROL DISTRICT. In July 1994, the District purchased its present facility and relocated its headquarters to Corona. At present, the District provides vector control services (mosquito, flies, rats, Africanized honeybees, black flies, midges and occasionally other vectors of minor public health importance) over an area of 240 square miles with a population of approximately 500,000.

🦟 Have you seen one of these around town?
This is a BG-Sentinel mosquito trap, one of the tools we use to monitor mosquito activity in our community. The trap helps us identify mosquito species and test for viruses like West Nile virus so we can respond quickly and target problem areas.

These traps play an important role in protecting public health and helping us stay ahead of mosquito-borne disease.

If you spot one, please leave it undisturbed, it’s working hard behind the scenes! 👏

Small water = big problem.

How many potential mosquito breeding spots can you find in this picture? 👀🦟 Take a close look, some are easy to miss! Mosquitoes only need a small amount of standing water to lay eggs.

🚨 Public Health Alert – West Nile Virus Mosquito Sample Detected in Jurupa Valley
The Northwest Mosquito and Vector Control District has confirmed the first detection of West Nile virus (WNV) in City of Jurupa Valley this season.
While most people infected show no symptoms, WNV can cause fever, headache, body aches, and, in rare cases, serious illness.
✅ Protect yourself and your family:
Dump & drain standing water around your home.
Defend yourself with insect repellent (look for DEET, Picaridin, IR3535, or Oil of Lemon Eucalyptus).
Dress in long sleeves and pants when outdoors, especially at dawn and dusk.
Check screens on windows and doors to keep mosquitoes out.
Your cooperation is vital to reducing mosquito breeding and lowering the risk of virus transmission.
