Lee brings expertise in urban pest behavior to Capitol Corridor IPM role
Sang-Bin Lee joined UC ANR as the urban integrated pest management advisor for the Capitol Corridor – comprising Sacramento, Yolo and Solano counties – to help communities manage urban pests such as cockroaches, termites and ants.
“My high-level hope is to improve public health and the well-being of people in the Capitol Corridor region by implementing and improving the IPM program,” Lee said.
A native of South Korea, Lee earned his bachelor's in biology from Pusan National University. After working in the food manufacturing sector (which included a stint in Brazil, where he learned basic Portuguese), Lee decided to pursue his passion for studying animal behaviors. During his master's program in ecology at Pusan National University, Lee investigated behavioral changes in zebrafish after pathogen infection.
“My goal was to detect fish with symptoms much earlier than conventional methods to prevent the spread of pathogens in fish farms,” he said.
Intrigued by research on social insects, Lee went on to earn a Ph.D. in entomology from the University of Florida, where he studied the social behaviors of termites. Lee has published 34 peer-reviewed articles in professional journals and has received several awards from Entomological Society of America and other professional societies.
He said that he finds urban pest management to be a fascinating discipline – and a very rewarding endeavor – in the field of entomology.
“My interests lie in the behavior of urban pests, and studying their behavior often provides a great opportunity to improve control measures,” Lee explained. “I have had many opportunities to communicate with people from the pest control industry and homeowners; conversations with these people often inspire me to work harder to help those who need my assistance.”
Lee is based in Fairfield, at the UC Cooperative Extension office in Solano County, and can be reached at sablee@ucanr.edu and (530) 574-9835. He is on X/Twitter @SangBinLee4.

Report: Making homes more resistant to wildfire can be affordable
Priorities include removing objects within five feet of a house, upgrading vents
Wildfire losses cost taxpayers and communities hundreds of billions of dollars each year, and preparing communities before a disaster occurs is the best way to avoid damage to homes and neighborhoods. Retrofitting existing homes can make communities safer while avoiding billions in disaster costs.
As Californians learn to live with wildfire, scientists encourage improving the structure and design of houses and other buildings to help them survive wildfire. A new report shows that even inexpensive changes can increase wildfire resistance.
“Retrofitting a Home for Wildfire Resistance” suggests that some of the most effective strategies to reduce the vulnerability of homes and neighborhoods to wildfire can be done affordably.
“This report is a practical tool that helps evaluate the relative costs and benefits of fire-hardening retrofits,” said Yana Valachovic, a University of California Cooperative Extension forest advisor, who reviewed the study. “These retrofits can substantially improve the odds that a home or building will withstand wildfire exposures to embers, radiant heat or flame contact.”
The report is co-authored by Kimiko Barrett, wildfire research and policy analyst for Headwaters Economics, a non-partisan research organization based in Bozeman, Montana, and Stephen L. Quarles, UC Cooperative Extension advisor emeritus, who has studied the vulnerability of the built environment to wildfire exposures and potential mitigation strategies.
In partnership with California's Department of Forestry and Fire Protection, or CAL FIRE, Barrett and Quarles examined the costs for improving the structure and design of existing homes to increase their wildfire resistance.
“This tool can also help homeowners build a budget and prioritize tasks that often feel overwhelming,”Valachovic said. “Everyone should prioritize removing combustible vegetation, mulch, and stored materials within the first five feet of a structure and upgrading vents to resist embers.”
Simple actions can reduce a home's vulnerability to wildfire
The report's conclusions are derived from a detailed examination of the latest available science on mitigation strategies and construction costs. The authors identified costs for retrofitting structures to meet and exceed California's building code (Chapter 7A) for wildfire resistance, but the general principles and conclusions can be applied in other states, adjusting for local economic and supply conditions.
For a typical 2,000-square-foot home in California, retrofitting costs can range from $2,000 to upwards of $100,000 for the highest level of protection.
“When we looked at the latest building techniques and cost data, we found some effective retrofitting strategies can be done for between $2,000 to $10,000,” said Barrett. “While the highest level of protection can cost more, it is often not necessary. Simple actions such as removing flammable materials from near the home and removing debris from the roof can be done at little to no cost.”
The authors also incorporated effective mitigation strategies that could reduce risk without requiring costly upgrades over the entire home, such as replacing siding only on the side of a home that is close to another building, such as neighbor's home or a detached garage, or replacing combustible deck boards next to the home with a noncombustible deck board or metal grate.
They also incorporated a systems approach, where the vulnerability of adjacent components are considered, and recommend steps such as placing noncombustible surfaces at the intersection between two components.
For example, Quarles said: “Adding a gutter cover and ensuring the adjacent edge of roof is not vulnerable by incorporating a metal drip edge and, if necessary, a noncombustible bird stop at the edge of the roof. Or, replacing a combustible deck board next to the house and, if necessary, adding metal flashing at the base of the exterior wall.”
Cost estimates in the report include those for upgrading a home's exterior walls, roof, deck, windows, doors, eaves, gutters and near-home landscaping – all areas likely to be exposed to embers, direct flames and radiant heat.
“The graphics detailing specific elements of the retrofitting process are very useful,” Valachovic said.
Charts, architectural renderings and a detailed appendix of cost estimates provide a basis for a general understanding of the methods and budgets that homeowners might consider when retrofitting their home for wildfire resistance.
Retrofitting for wildfire can make communities safer
Contractors and others seeking information about building wildfire-resistant homes can gain valuable insights from this analysis, along with retrofit costs generated by the California Wildfire Mitigation Program.
“This analysis demonstrates that investing in wildfire-resistant retrofitting for homes is a cost-effective strategy to protect communities that could save billions in disaster costs,” said Barrett. “As more people live in fire-prone areas, we must also take a closer look at retrofitting homes to be stronger and more durable.”
While the authors hope Californians use the information to protect their homes, people who work in construction, development, design and policy also can use the information to show that retrofitting homes for wildfire resistance is an effective way to protect communities.

Barnes brings hometown knowledge to UCCE in Lake, Mendocino counties
New Cooperative Extension director has worked extensively with Native American communities, youth groups
Growing up in Upper Lake, along the “North Shore” of Clear Lake, Matthew Barnes lived near several of the Lake County region's seven federally recognized tribes. Although he counted several Native Americans among his diverse circle of childhood friends, and was very familiar with those communities, Barnes was nonetheless quite nervous when he was appointed in 2009 as the inaugural executive director of the Boys & Girls Club of the Pomo Nation.
Barnes – a non-Native of European and Filipino descent – vividly remembers the tribal administrator paying him a visit on one of his first days on the job. “He said, ‘Hey, you have two ears and one mouth, so listen twice as much as you speak and you'll be fine,'” Barnes recalled. “And that's definitely stuck with me.”
That approach is continuing to guide Barnes in his new role as University of California Cooperative Extension director for Lake and Mendocino counties. He will guide and support research, outreach and education activities to meet the area's agriculture, natural resources, and youth and community development needs.
Since starting in May, Barnes has been getting a crash course from UCCE advisors and staff on viticulture research, pest management practices, 4-H camps, and a host of other projects and programs – while also meeting with local communities on the region's most pressing challenges.
“What I've been doing – and will continue to do – is just to listen and learn, and when I can add value to a conversation or project, then I'll do that,” Barnes said. “But leadership to me starts with the relationships we build – with our staff and with the community.”
Bringing a range of experiences in youth programs, social services
One area in which Barnes will certainly add value is developing youth and community programs. During his time with Boys & Girls Club of the Pomo Nation, it was one of only three Boys & Girls Clubs established on tribal land in California. In that role, Barnes faced the unique challenge of integrating the Boys & Girls Club curriculum into a community for which it was not originally designed.
By adapting the curriculum to include culturally relevant topics, Barnes transformed the program into a model that eventually aided in the creation of a Native American-focused branch, Boys & Girls Clubs of America Native Services.
“This initiative now serves as a national standard for Boys & Girls Clubs on tribal lands,” Barnes said.
He later became a director of California Tribal TANF (Temporary Assistance for Needy Families), a direct cash assistance and supportive services program for Native American families in 17 counties across the state.
During his decade of TANF work, Barnes launched career development programs, alcohol and other drug counseling programs, and cultural revitalization initiatives. Some of the programs are still running and serving communities to this day.
“The trick is making those programs something that participants can see the value in,” Barnes explained. “And to do that, you go into the communities and talk to people and listen to what they need – instead of you telling them what they need.”
Barnes' experience partnering with Native American communities is just one of the many strengths he will bring to UCCE and UC Agriculture and Natural Resources.
“We're very excited to have Matthew join the UC ANR family,” said Lynn Schmitt-McQuitty, UC ANR's director of County Cooperative Extension. “His personal knowledge of Lake and Mendocino counties and his previous work with Indigenous populations will be a tremendous asset to extending and elevating our work.”
Immediately prior to joining UC ANR, Barnes served as director of Lake County's Upward Bound program, which helps students from three local high schools experience and prepare for higher education.
“Overall, what drives me personally is the opportunity to make an impact on communities, on youth, and on people in general through program development and management,” Barnes said.
Inspiring young people as a mentor
Barnes' passion for youth development – and the impetus for his bachelor's degree in social work from Cal Poly Humboldt – can be traced to his AmeriCorps experience while he was attending Mendocino College. For two years, he worked as a tutor for young people, in Lake County and then in Sonoma County, and saw firsthand the difference educators and mentors can make in their lives.
“You could say I kind of caught the bug – just seeing the light bulbs go on when you're helping a youth of that age,” Barnes said.
From there, Barnes took a position directing teen programs for the Boys and Girls Club of Healdsburg, where he began to fully appreciate the importance of trusted adults simply “being there” for young people as a listening ear for whatever they want to talk about.
Among the many teens Barnes worked with, “Rodrigo” was a middle schooler who was pegged by his school and community as someone who could “slip through the cracks.” Rodrigo was the last to go home at the end of each day, and Barnes would chat with him – answering his questions about life or just talking about a new rap album.
“I realized I was ‘that person' for him – that person outside his house, outside his school,” Barnes said.
Even after Barnes left the Boys and Girls Club, Rodrigo – bound for university – invited him to his high school graduation. Barnes said it is tremendously gratifying to know he had a “small role” in shaping the path for Rodrigo – and countless others.
“Their success is still theirs; it's not necessarily because of me,” Barnes added. “My job is to do what I can in the moment to hopefully plant some seeds that may sprout in the future.”
Settled in Middletown, not far from his hometown, where he and his wife are raising two children, Barnes is now positioned to help nurture a flourishing Lake County and resilient Mendocino County.
“I feel like my past experiences, both in life and my career, have prepared me for this,” Barnes said.
