![CDC General Recommendations for Flea Disease Prevention: reduce rodent and animal habitat around your home; limit exposure to wild or stray animals; wear repellent if you will be exposed to fleas; keep pets on flea control products year round; bathe and brush pets regularly; limit pet time outdoors; clean pet bedding frequently with soap and water; do not allow pets to sleep on your bed; do not accidentally swallow a dead flea.](https://ucanr.edu/blogs/UCIPMurbanpests/blogfiles/108312small.png)
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.

As vacation season begins, people will be traveling much more in the coming months. Whether you'll be staying at a hotel, hostel, motel, rental home, or summer camp, you should always be on the lookout for bed bugs. A bed bug check takes only a few minutes to complete and can give you and your family peace of mind when staying at new places.
Bed bugs are small insects, but big enough to see with the naked eye. They are oval shaped, wingless, and reddish brown. Bed bugs feed only on human blood, usually at nighttime while we are sleeping.
It's important to remember that bed bugs can occur anywhere and are not always an indication of poor hygiene or care. Bed bugs can be moved to new places on furniture, luggage,...

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...

The invasive pest spotlight focuses on emerging or potential invasive pests in California. In this issue we are covering West Nile virus.
West Nile Virus Facts
West Nile virus disease was first reported in California in 2003 and has become the most common and serious vector-borne disease in California. With the exceptionally wet weather in 2023, reported cases of this mosquito-borne virus doubled compared to the previous year.
West Nile virus is spread by mosquitoes in the genus Culex. Usually, the virus passes between mosquitoes and birds, but mosquitoes can also transmit the virus to humans, horses, and other domestic animals.
Because mosquitoes can get the virus...
