A Growing Concern in Our Backyard
Placer County residents have a new reason to be on alert. Recently, the Placer Mosquito & Vector Control District confirmed captures of invasive Aedes mosquitoes—including Aedes aegypti, also known as the yellow fever mosquito—in Roseville and Rocklin. While the Asian tiger mosquito (Aedes albopictus) has not yet been confirmed here, its rapid spread in other California counties means it’s only a matter of time before it arrives.
Compounding the threat, West Nile virus-positive mosquitoes were detected west of Roseville in June 2025. This means both invasive and native mosquito species are now active in our area, some carrying potentially dangerous diseases.
Public Health Implications
The confirmed captures are more than just a pest problem—they’re a public health concern:
• Daytime and Evening Biting Threats
• Aedes aegypti and Aedes albopictus bite during the day, often multiple times.
• Culex species, which spread West Nile virus, are most active from dusk to dawn.
• Disease Transmission Risk
• Aedes mosquitoes can transmit Zika, dengue, chikungunya, and yellow fever.
• Culex mosquitoes are the primary vector for West Nile virus in California.
• Rapid Spread & Resilience
• Aedes eggs can survive up to 6 months in dry conditions, reactivating when exposed to water.
Bottom line: once these species get a foothold, they’re extremely difficult to eradicate without community-wide action.
Homeowner Action Plan: Step-by-Step Mosquito Defense
You can dramatically reduce the risk around your home by taking these seven proactive steps:
1. Stay Informed
Follow updates from the Placer Mosquito & Vector Control District and report unusual daytime mosquito activity.
2. Eliminate Standing Water
• Dump water from containers like plant saucers, toys, buckets, and tires.
• Clean gutters and keep fountains or birdbaths refreshed every 4 days.
3. Block Breeding Sites
• Seal rain barrels with fine mesh.
• Fill tree holes or low spots with sand or gravel.
4. Treat Undrainable Water
• Use Bti mosquito dunks in water features—safe for pets and wildlife, lethal to mosquito larvae.
5. Protect Yourself
• Wear long sleeves and pants.
• Use EPA-approved repellents like DEET, picaridin, IR3535, or oil of lemon eucalyptus.
6. Join Community Efforts
Organize or participate in neighborhood clean-up events to remove potential breeding sites.
7. Report and Cooperate
Allow vector control inspections on your property and report dead birds or high mosquito activity.
Pets in the Plan: Year-Round Allies
Your pets—and some natural allies—can be part of the solution:
• Mosquitofish (Gambusia) in ponds or large water features eat larvae before they become biting adults.
• Dragonflies & Damselflies thrive in yards with native plants and shallow water, hunting mosquitoes daily.
• Keep pet water bowls clean and refreshed to avoid creating breeding sites.
