BOO! Think cool weather scares the mosquitoes away?🦇🦟

Female mosquitoes feed on blood, making a vampire costume a fitting Halloween disguise for this winter marsh mosquito (Culiseta inornata).

While most mosquito activity in San Joaquin County declines in cooler weather, some local species tolerate cool temperatures and remain active. Cooler weather doesn’t mean every mosquito disappears!

But mosquitoes don’t have to be scary! Keep these bite-prevention habits handy:

🦟 Use an EPA-registered insect repellent when mosquitoes are active. Always follow the label directions.

👕 Wear loose-fitting, layered clothing with long sleeves and pants to help prevent bites.

💧 Dump standing water around your home. Check buckets, plant saucers, toys, and other containers weekly and after rain.

Enjoy the spooky season—and keep up the bite prevention!

Is your landscaping growing mosquitoes? During a yard inspection for a mosquito problem, one of our technicians found mosquitoes developing in a landscape rock.

Check all areas that use water in your yard. Drain or eliminate any standing water and adjust sprinkler direction and watering schedules to prevent mosquitoes from using your yard to multiply.

🔎💧Spot the source. Stop the swarm! 🚫🦟

🦅 An Unexpected Visitor at SJC Mosquito & Vector Control District

Yesterday, an injured hawk was found in our District parking lot. Unable to fly and close to busy Airport Way, it needed help and a safe place to recover. District staff safely secured the hawk and reached out to Tri County Wildlife Care.

While our District lab tests dead birds for West Nile virus, caring for injured birds is a job for wildlife professionals. Thank you to Tri County Wildlife Care for picking up this hawk and providing the care and rehabilitation it needs!

Rain or sprinkler water can collect in the smallest places. Even a bottlecap or a discarded bottle can collect enough water for mosquitoes to develop!

Mosquito eggs laid as the weather cools can also remain dormant through the winter and 𝐇𝐀𝐓𝐂𝐇 𝐍𝐄𝐗𝐓 𝐒𝐏𝐑𝐈𝐍𝐆.

Take a few minutes to check your yard 𝐚𝐟𝐭𝐞𝐫 𝐭𝐡𝐞 𝐫𝐚𝐢𝐧 𝐀𝐍𝐃 𝐨𝐧𝐜𝐞 𝐚 𝐰𝐞𝐞𝐤:

💧 𝐃𝐑𝐀𝐈𝐍 standing water from plant saucers, buckets, wheelbarrows, or other items, and 𝐂𝐋𝐄𝐀𝐍 gutters
🧽 𝐒𝐂𝐑𝐔𝐁 the sides of containers to remove mosquito eggs, which can hatch when water & warmth returns.
🗑️ 𝐃𝐈𝐒𝐂𝐀𝐑𝐃 trash and place recyclables in 𝐜𝐨𝐯𝐞𝐫𝐞𝐝 bins.
🏠 𝐒𝐓𝐎𝐑𝐄 items indoors, under cover, or upside down so they can’t collect water.

A quick yard check 𝐧𝐨𝐰 helps prevent mosquitoes 𝐥𝐚𝐭𝐞𝐫!🦟

🔬 Exploring the science behind mosquito control

Last week, San Joaquin County Mosquito & Vector Control District participated in the San Joaquin County Office of Education's Dinner with a STEM Professional for students in grades 6–12.

Our Vector Ecologist, Noah Moral, and Public Information Officer and former Assistant Entomologist, Sumiko De La Vega, shared their career journeys and highlighted the science-based roles that help our District protect the community from mosquitoes and mosquito-borne diseases.

An insect specimen collection, live mosquito life cycle display, and digital microscope gave students an up-close look at some of our work! 🦟

Thank you, SJCOE STEM, for the opportunity to share the science behind our work and help inspire the next generation of STEM professionals!

🦟🔬🐟 Hands-On Mosquito Science at Durham Ferry Outdoor School!

Mosquito education goes beyond the classroom! Earlier this month, the San Joaquin County Mosquito & Vector Control District visited the San Joaquin County Office of Education Venture Academy Family of Schools Durham Ferry Outdoor Education Center, where we taught 7th–12th grade students about mosquitoes, mosquito prevention, and the science behind mosquito control through interactive, hands-on activities.

Students rotated through stations featuring live mosquitoes, microscopes, mosquitofish, and everyday items containing mosquito eggs so tiny that they look like specks of dirt!

To wrap up the day, students experienced biological mosquito control firsthand by releasing mosquitofish into the horse watering troughs, where they will help control mosquito larvae naturally.

Thank you to Durham Ferry Outdoor School for inviting us! We love helping students understand the importance of mosquito control and giving them the knowledge and tools to reduce mosquitoes on the farm or at home!

A big 𝐭𝐡𝐚𝐧𝐤 𝐲𝐨𝐮 to our seasonal team!

Today marks their final day with the District this season, and we’re grateful for their hard work during our busiest months.

From mosquito surveillance and testing to door-to-door yard inspections, catch basin treatments, and netting mosquitofish, they’ve supported essential work in the field and the lab to help protect our communities. Our seasonal staff help us meet the demands of the busy mosquito season, bringing extra hands and a willingness to jump in wherever needed.

To our seasonal crew: we couldn’t do this work without you! Thank you for all you’ve done to help protect our communities. We appreciate all your hard work!

🍂🦟Warm Fall Days Keep Mosquitoes Active

The calendar says fall, but warm temperatures allow mosquitoes and West Nile virus to remain active. It's important to keep up your mosquito prevention routine even in October!

🛡️ Prevent mosquito bites:

• Apply an EPA-registered insect repellent when mosquitoes are active, following label directions.
• Dress in loose layered clothing with long sleeves and pants, when practical.
• Repair damaged door/window screens and seal gaps around doors/windows to keep mosquitoes outside.

💧 Prevent mosquito development. Check your yard every week to eliminate standing water:

• Dump or drain items holding water, even as little as a bottlecap!
• Screen yard drains and rain barrels.
• Scrub container sides to remove mosquito eggs.
• Throw away unused containers or store them upside down so they cannot collect water.
