Fleas can be found on pets year-round, but populations tend to increase dramatically in spring and summer when temperatures are warmer. Larvae develop rapidly in areas where temperatures reach 70° to 90°F. Fleas are a major concern for pet owners as they can give dogs and cats tapeworms, but they can also transmit flea-borne typhus to people and spread plague to wild animals like ground squirrels. These blood-sucking pests can be introduced to backyards from feral cats, squirrels, opossums, and other wildlife.
To learn more about fleas, the diseases they can spread, and their management, check out the recording of UC IPM's Urban & Community IPM Webinar from June 2024 at https://www.youtube.com/watch?v=b-w7J6mkTeM. You'll hear from flea expert Dr. Laura Krueger of the Orange County Mosquito and Vector Control District on how you can protect yourself and pets from fleas.
A 2024 article by Lela Nargi of The Guardian discussed the issue of potable water in schools and how inconsistent regulation can put children at risk for under-hydration or lead exposure. The article highlighted a 2022 study by NPI's Christina Hecht and collaborators and included quotes from Hecht, who described the development of legislation for drinking water in the federal child nutrition programs. In 2010, the Healthy, Hunger-Free Kids Act made free potable drinking water a requirement during meal times at all US schools participating in the National School Lunch Program and childcare facilities participating in the Child and Adult Care Food Program. However, states' varied implementation of the law plus a lack of funding for drinking water needs has left some schools with inadequate water sources or compromised quality. While a 2019 USDA survey of 1,257 schools indicated a 95% compliance rate with the Healthy, Hunger-Free Kids Act, experts including Christina Hecht, who coordinates the National Drinking Water Alliance with the Nutrition Policy Institute, highlight how this survey did not collect adequate data to determine whether safe and appealing drinking water was truly accessible. Lead contamination is a primary concern. Hecht and partners' 2022 study found 13% to 81% of 5,688 schools in seven states with available data had tap water with lead levels above 5 parts per billion (ppb). For comparison, FDA requires that bottled water have no more than 5 ppb of lead while the American Academy of Pediatrics recommends a maximum of 1 ppb for school drinking water. States have varying requirements for lead testing of school and licensed childcare drinking water and, while federal funds for testing have been available since 2016 through an EPA-administered program, it was only with the passage of the Bipartisan Infrastructure Law of 2021 that federal funds were allocated to assist schools with remediation of lead in tap water.

Aedes mosquitoes can transmit some of the most debilitating and deadly mosquito-borne pathogens to humans, such as Zika virus, dengue virus, chikungunya virus, and yellow fever virus. One Aedes species is also capable of transmitting heartworm to dogs. These invasive mosquitoes are now present in many regions of California, from Shasta County to San Diego County. View a map of Aedes distribution by county.
The yellow fever mosquito (Aedes aegypti), the Asian tiger mosquito (Aedes albopictus), and the Australian backyard mosquito (Aedes notoscriptus) are unlike most native mosquitoes. They prefer to bite during the day, especially around your legs and ankles. Adults are black with white stripes on their legs and back.
Many Aedes mosquitoes live in close contact with people and can breed in backyards and even inside homes. They are known as “container breeding mosquitoes” because they lay eggs in small containers, such as flowerpots or old tires. Eggs are laid in moist areas just above the water surface, can overwinter, and are resistant to drying so may remain viable for months or longer. Their entire life cycle can occur in as little as 7–8 days.
What can you do?
In many areas of California, public Mosquito and Vector Control Districts work to keep mosquito numbers down to tolerable levels. Since these mosquitoes primarily breed on residential properties, you can help by eliminating mosquito breeding sources around your home. This includes draining standing water in rain gutters, buckets, and watering cans. Change the water in pet dishes and bird baths weekly. Clean up clutter in the yard since these mosquitoes can lay their eggs in anything that can hold water. Standing water or ponds can be treated with Bacillus thuringiensis subspecies israelensis (Bti) or mosquito fish. Wear mosquito repellents and protective clothing outdoors. Keep mosquitoes out of your home by keeping fine mesh screens on windows and doors in good condition.

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.
