So we found a dead bird in West Roseville that tested positive for West Nile virus (WNV).

👉 But what does that mean for you?

Birds can spread WNV to mosquitoes, so dead birds help us identify areas where the virus may be circulating. However, a positive bird does NOT mean all mosquitoes in the area are carrying WNV.

👉 So what happens next?

We’ll increase surveillance in the area where the bird was collected. This includes trapping and testing mosquitoes for WNV. So far, no mosquitoes in the area have tested positive for the virus.

🦟 West Nile Virus Update

We have confirmed our first dead bird of the season to test positive for West Nile virus. The dead bird was collected in West Roseville near Pleasant Grove Blvd. & Fiddyment Rd.

Placer Mosquito District is increasing mosquito surveillance in the area and reminds residents to protect themselves by using EPA-registered repellent and wearing long-sleeved protective clothing.

Remember to report dead birds to the California Department of Public Health WNV call center at 877-WNV-BIRD (877-968-2473) or visit westnile.ca.gov.

🦟 DID YOU KNOW? | California Invasive Species Action Week

The invasive mosquito Aedes aegypti is different from other mosquito species in that it only needs a very small amount of water to survive and reproduce.

Even something as small as a bottle cap, plant saucer, or forgotten container can hold enough water for it to lay eggs.

Help stop it at the source:
✔ Dump and drain standing water weekly
✔ Empty and scrub small containers
✔ Check gutters, buckets, and outdoor items

Small amounts of water can lead to big mosquito problems.

🦟 This week is California Invasive Species Action Week ( ), a statewide effort to raise awareness about invasive species and encourage community action to help protect California’s natural resources and public health 🌎

At PMVCD, one invasive species we are especially concerned about is the invasive Aedes aegypti mosquito.

First detected in Placer County in 2019, these mosquitoes are aggressive daytime biters that can thrive in even the smallest amounts of standing water, making them some of the sneakiest mosquitoes around our homes and neighborhoods 🏡💧

Stay tuned this week as we share Aedes facts, prevention tips, and information about how we’re working to reduce their impact and protect the health and safety of our community 💙

Catch basins are everywhere you look, from busy roads to neighborhood streets. Ever wonder what may be down there? 👀

🌧️ They collect and drain water, but did you know they can also create the perfect environment for mosquitoes to breed?

Our technicians are on it! They travel all over Placer County, inspecting and treating catch basins for mosquito larvae. 🦟

This season, their efforts resulted in an impressive 8,205 inspections and 5,879 treatments. So the next time you pass a catch basin, know that our team may have already been there, working behind the scenes to keep mosquitoes in check and lowering the risk for vector-borne diseases. 🛡️

🦠🌿 As May comes to an end, we’re wrapping up Lyme Disease Awareness Month 💚

While learning about the risks, symptoms, and prevention of Lyme disease is important year-round, we hope you learned something new from our educational posts this month! 🥾🕷️🔎

Some quick facts:

👉 Lyme disease is an illness caused by Borrelia bacteria.

👉 Not all ticks carry Lyme disease. In Placer County, Ixodes pacificus (Western black-legged) ticks are the primary known vector of Lyme disease.

👉 Early detection and treatment are the most effective ways to help minimize the long-term effects of Lyme disease.

👉 Wearing long sleeves and pants, using EPA-registered insect repellents, and avoiding tall grasses and brushy areas are some of the best ways to protect yourself while outside.

Awareness, prevention, and early action all play an important role in staying safe outdoors!

☂️ It may almost be summer, but the rain returned for a brief encore.

🌧️ These unusual showers in Placer County create the perfect opportunity for pesky mosquitoes to lay their eggs in freshly filled containers. A friendly reminder to dump and drain standing water after the rain to help reduce mosquito breeding. Let’s not give these mosquitoes a chance. 🏡💧
