Invasive mosquitoes detected in Winters, again

Support Local Journalism


Along with summer and warming weather, the invasive Aedes Aegypti, also known as the Yellow Fever Mosquito which is known to transmit the Zika virus, made its appearance in Winters, again.

Last Wednesday, the Sacramento-Yolo Mosquito and Vector Control District dispatched a truck to Winters in the early morning hours and sprayed for the invasive mosquito species detected. Luz Maria Robles, the District’s public information officer, said the detection was on Abbey Street.

Robles told the Express they expected to find the invasive species again this year, they just didn’t expect it so early in the season.

The District lays traps for the invasive species all winter. The Aedes Aegypti is a small, dark mosquito known as the “container breeder” because it lays eggs during the winter in containers, such as planting pots and the dry eggs can lay dormant for months until contact with water and the right hatching conditions.

Mosquitoes carry and transmit diseases to both humans and animals. Diseases like West Nile Virus, Zika and some lesser-known ones are harmful to humans and animals. Dogs develop heartworms from mosquito bites.

The most prevalent disease carried by mosquitoes in the region is West Nile Virus, which has been present since 2004. The disease is carried by birds and mosquitoes act as a vector carrying the disease between birds and humans. Most cases of the virus are mild in humans, but the virus can cause life-threatening illnesses.

Two positive infected mosquito detections have been made in Yolo County this year. On June 8, the District reported two West Nile Virus positive mosquitoes trapped in Knights Landing and multiple positive detections of the invasive species in Winters.

The public is encouraged to drain all water on their property, discard unwanted items that can collect water, scrub containers that are not in use and to report day biting mosquitoes.

Robles encouraged residents to sign up for email notifications on their website at for email notifications when spraying is scheduled to occur.

To prevent mosquito bites, the district recommends use of an effective repellent containing DEET, picaridin, IR3535 or lemon and eucalyptus oils when outdoors. DEET repellent wipes and informational brochures are available free of charge from the District.

Just as it is time to clean off the barbecue and ready outdoor furniture, the District suggest community members start practicing the “District D’s” of mosquito prevention:

Drain standing water that may produce mosquitoes.

Dawn and Dusk are times to avoid being outdoors.

Dress appropriately by wearing long sleeves and pants when outside.

Defend yourself by using an effective insect repellent. Make sure to follow label directions.

Door and window screens should be in good working condition.

District personnel are also available to address any mosquito problems.
