Being bothered by mosquitoes and troubled about the risk of diseases?
Mosquitoes are not just annoying. They can be deadly.
The seminar, titled "Natural Mosquito Control," is part of the California Farm Academy Speaker Series, and will take place from 4:30 to 7:30 p.m. at CLBL, located at 40140 Best Ranch Road, Woodland. The event begins with pizza and mingling, “until about 5:30, and then the presentation,” said spokesperson Julia Hobbs Thomas. Reservations can be made on Eventbrite.com at this link.
The event is billed as "a discussion about both native and invasive species, what diseases they can spread, and how healthy ecosystems can create habitats that keep them in check. Agriculture can play a big role, because pesticide use can damage populations of beneficial insects like dragonflies. You'll also pick up a few tips to avoid being bitten!"
Wood-fired pizza and beverages will served beneath the canopy of a century-old valley oak, she added. Attendees can also bring food or beverages to enjoy or share.
Said Attardo: “I will be focusing on educating people about the most imminent risks of mosquito-borne diseases in California coming from West Nile Virus—due to native Culex mosquitoes predominantly—and Aedes aegypti vectored diseases such as dengue, Zika, Chikungunya, and yellow fever. I'll discuss places these mosquitoes breed in suburban and urban habitats, as well as ways people can eliminate and prevent creation of breeding sites.“
Attardo specializes in medical entomology, reproductive physiology, molecular biology and genetics. He recently hosted a UC Davis symposium, sponsored by the Deaprtment of Entomology and Nematology and the Pacific Southwest Center of Excellence in Vector-Borne Diseases, on “Tule and Cattail: A Tale of the Marsh Economy and Its Role in Human Health and Wellbeing” that aimed "to advance the land management aims of local tribal communities and provide a platform to educate about the importance of maintaining wetland biology for climate change, ecological and human health, and vector control." Attardo addressed the symposium with collaborator Diana Almendariz, a traditional ecological knowledge specialist and a cultural practitioner of Maidu/Wintun, Hupa/Yurok traditions, heritage, and experiences.
A global expert on vectorborne diseases, and renowned for his groundbreaking work on tsetse flies, Attardo received the Medical, Urban, and Veterinary Entomology Award in 2022 from the Pacific Branch, Entomological Society of America. (See news story)
He joined the UC Davis Department of Entomology and Nematology in 2017 from the Yale School of Public Health, where he served as a research scientist studying the reproductive biology of tsetse flies. Attardo holds a doctorate in genetics (2004) from Michigan State University, studying with Alexander Raikhel.

The University of California Statewide IPM Program (UC IPM) has an exciting, newly updated resource to help you better understand pesticide active ingredients and the risks different active ingredients pose to people and the environment.
The Pesticide Active Ingredient Database is designed for urban audiences including the general public, Master Gardeners, nursery and garden center staff, pest control operators, landscapers, and more. The active ingredients included in this database can be found in many commonly available pesticide products in California. The database contains a variety of pesticide types, including insecticides, herbicides, rodenticides, antimicrobial products, and more.
Each active ingredient in the database has its own page where you can learn what it is, how it works, and what pests it can control. You can also view example products available to the general public or licensed professionals, and a table displaying the potential hazards of the active ingredient. The potential hazards table includes toxicity information for water quality or aquatic wildlife, natural enemies, honey bees, and people or other mammals. A glossary of pesticide terms is available as well to help you understand pesticide terminology.
You can use this database to compare toxicity ratings of pesticides by clicking the “Compare Risks” link or button found on UC IPM's Pest Notes fact sheets. This will help you find the least-toxic pesticide active ingredients to control a specific pest.
We hope you find this newly updated resource helpful and share with others who may be interested.

Check out our webinars planned for summer 2024:
June 20, 2024 - Flea Control & Diseases: Starting from Scratch
Fleas are small but mighty insects that are important medical and veterinary pests. They can vector pathogens and parasites, and their bites cause discomfort and irritation. In this webinar you'll learn how to keep yourself and pets safe from fleas and flea-borne diseases.
July 18, 2024 - Common Wood Decay Fungi in Landscape Trees of California
Trees are a valuable part of our landscapes. However, older trees can harbor wood decay fungi, which can be associated with an increased risk of tree failure or branch breakage. In this webinar, urban forestry expert Igor Lacan will discuss some wood decay fungi that are commonly seen on trees in urban landscapes in California, the effect(s) of fungi on the tree, and related considerations in tree management.
August 15, 2024 - Back to School Pests
With students heading back to school, now is a good time to talk about pests in schools and childcare centers. In this webinar, Karey Windbiel-Rojas will talk about head lice, bed bugs, rats, cockroaches, and more. We will also cover the use of disinfectant wipes and pesticide safety.
September 19, 2024 - Improving Professional Ant Control Services
In California, the Argentine ant is among the most common nuisance ant species treated by pest management professionals and the general public. In this webinar, you will learn how the university researchers and pest management companies are working together to improve pest ant management in urban residential settings.
Webinar topics for October and November will be announced mid-summer.

I've spoken with countless gardeners over the years who wish to start their own bee haven. That's great -- the bees need all the help we can give them. But the most misunderstood part of the process is how much preparation needs to take place before a single plant goes in the ground.
As the Haven winds down, I'd like to share some tips on preparing to install your own bee garden.
Many gardeners are removing a turf lawn to create their bee haven. It's important to take the time to do this correctly so your garden doesn't revert to a weedy mess. UC IPM has great information about turf removal, including how to identify your turf species (knowing your species helps with removal) and how to remove existing turf.
If you are opposed to using herbicides to kill your lawn, solarization can also be used. For most lawns it will take longer and be less effective. That is definitely the case for bermudagrass lawns that are common in California. Figure 1 summarizes the pros and cons of various turf removal methods. For more own bermudagrass lawn, I used a combination of herbicides, sheet mulching, and hand removal.
Finally, weed barrier fabric is never recommended. It prevents ground-nesting bees from accessing the soil, traps weed seeds that grow through the fabric and become impossible to remove, and breaks down over time to leach microplastics into the ground.
Whatever methods you use, patience is key. Plan on at least one year of preparation before planting.
It's also essential to know your soil type and its physical characteristics. Jar tests and drainage tests provide important information about how your soil will hold water. In California, the UC Davis Soil Web has detailed soil maps; these may be less accurate if you are in a new development where there has been recent soil disturbance or addition of new topsoil.
Finally, watch the pattern of sun and shade in your garden for a year before planting. Many winter-blooming 'full sun' plants will do fine under deciduous trees as they are in full sun when flower buds are forming. In the hotter part of California, some 'full sun' plants may need shade in afternoon.
The final task while you're in the process of killing your lawn is to learn about and choose plants for your garden. Garden tours are a great way to start this process....you'll see what grows in your area and have the chance to speak to other gardeners. These are often sponsored by municipal water authorities. Botanic gardens and independent garden centers with knowledgeable staff are other great resources.
The UC Master Gardener program has trained volunteers throughout the state to provide research-based gardening information. They are a fantastic resource and hold educational programs like this one for the public. Finally, garden clubs and the California Native Plant Society hold tours, plant sales, and educational events.

May is here and with all the fluctuations in our weather lately, there is a lot going on in the landscape! Follow these general tips for the month of May to prevent pests. To see more tips specific to your region, visit the Seasonal Landscape IPM Checklist on the UC IPM website.
- Look for the invasive Asian citrus psyllid on new citrus growth. If not known to occur in your area, report findings to your local county agricultural commissioner.
- Prune winter-flowering shrubs like camellia before next year's flower buds form.
- Check plants for leaf stippling or webbing from spider mites. Irrigate adequately, mist leaf undersides daily, reduce dustiness, or spray horticultural oil to manage them.
- Monitor for grape diseases like powdery mildew, Eutypa dieback, Phomopsis cane and leaf spot, and others. Prune, remove, or treat as appropriate.
- Cover fruit trees with netting to exclude birds and other vertebrate pests.
- Watch for yellowjackets and other wasps building nests in undesirable locations. Knock down newly started nests and use lure or water traps to control populations.
- Fertilize caneberries, citrus, deciduous fruit trees, palms, and heavily-flowering shrubs with a slow-release product if not done in March or April.
- Monitor stone fruit trees for pests such as aphids, borers, brown rot, caterpillars, powdery mildew, and scale insects.
- Manage ants. Plants infested with honeydew producing insects like aphids, whiteflies, and mealybugs may attract ants who take that honeydew back to the nest to feed the colony. Manage ants around landscape and building foundations using insecticide baits and trunk barriers.
