District 2024 Open House

We are excited to invite you to our 2024 Open House! The Open House will be held at our facilities (1351 Rollins Road, Burlingame) on Saturday, June 15th from 12-4pm. Visit HERE to learn more and sign up for updates.

We hope to see you here!

Western Treehole Mosquitoes are Active

We've been receiving a lot of calls about day-biting mosquitoes, especially from people who live in or near wooded areas. The samples we've identified in the laboratory are Aedes sierrensis, the western treehole mosquito. Spring is the start of their season, and as their name suggests, these mosquitoes lay their eggs in the cavities of oaks and several other types of trees. Treehole mosquito larvae can also be found in discarded tires or containers where plant debris and water have accumulated. Learn more about these mosquitoes and how to prevent them HERE.

Mosquito Look-Alikes are Out!

We've also been receiving a lot of calls about 'giant mosquitoes' (crane flies), 'swarms of mosquitoes' (midges), and many other insects that are commonly confused for mosquitoes. This spring has been particularly busy with insect life. We can help you identify insects if you can provide a sample, and you can learn more about many of the look-alikes HERE.

Board News

Colma trustee, Laura Walsh

Board Trustee Laura Walsh, received recognition from Colma's Town Council for serving as Colma's representative on the District's Board since 2020. Colma Mayor John Goodwin remarked, "Laura Walsh has been the Town’s representative for the San Mateo County Mosquito Vector Control District for the past several years. In that time, she has put out information to the Council, and therefore, to the residents of the Town, about services that the Vector Control District provides... The volunteer position doesn’t come with many platitudes, but she attends every meeting and does a good job in her role as the Town’s representative with the District. We appreciate your work, Laura. Thank you!"

Brisbane trustee, Carolyn Parker

The District was saddened to learn of the passing of Board Trustee Carolyn Parker, who had served as the City of Brisbane's representative to the District's Board since 2017. Carolyn was a dedicated Board member, an active community member, and an avid environmentalist. Her contributions to the District's oversight were thorough and thoughtful, two characteristics particularly valuable in the development and oversight of government policy and finance. We are grateful for Carolyn's many years of service, and her presence on the Board will be missed.

Staff News

Several staff attended conferences over the past few months. Attending conferences allows us to stay up-to-date on novel and emerging mosquito and vector control research and methods. Staff members Angie and Arielle attended the American Mosquito Control Association meeting in Dallas, while staff members Ryan, Vanessa, Eric, Justin, and Rachel attended the Vertebrate Pest Conference in Monterey. Staff earned CEU credits for attending presentations on key topics, which allows our staff to keep their CDPH vector control technician certifications active.
