July 20, 2023: Natural Enemies & Beneficial Bugs: What are they?
While some insects can be damaging pests, many others are actually useful and keep pest species in check by parasitizing them or preying on them. These beneficial bugs are known as natural enemies and are vital to help keep pests from getting out of control. In this webinar, learn about natural enemies, how to identify them, and how they...

During summer swarming season, homeowners urged to check for signs of Formosan subterranean termite
In the lottery of troublesome termite infestations, “Roger,” a Rancho Santa Fe homeowner, hit the jackpot (a pseudonym is used to protect his privacy). In 2021, his house in San Diego County was identified as home to only the fourth documented colony of the Formosan subterranean termite (Coptotermes formosanus) in California.
“FST is one of the most destructive urban pests in the world,” said University of...

The cool, wet spring that California has experienced this year comes with many benefits, but also some drawbacks. For the false chinch bug, a small insect commonly found in grassy or weedy areas, this year's weather may result in a population boom. For those who live near grassy areas, it could mean hundreds to thousands of these insects invading homes and other nearby structures.
False chinch bugs are a common springtime pest. They overwinter in unmanaged areas and often feed on winter weeds, like mustard. As spring plant growth increases, so do populations of false chinch bugs. When spring weeds die back, the false chinch bugs will then move to landscape plants and crops to feed. They are usually only a pest of...
The Formosan subterranean termite (FST), Coptotermes formosanus, is a very destructive pest first reported in California in 1992 in La Mesa, San Diego County. FST has since been found in Canyon Lake, Riverside County, Rancho Santa Fe (San Diego County) and Highland Park (Los Angeles County).
While this termite species is currently only found in a few locations in Southern California, it's important for residents and professional pest managers to be aware of them. Wood destroying pests can easily be moved through human activities.
To identify Formosan termites, UC IPM advisor Dr. Siavash Taravati and Dr. Chow-Yang Lee of UC Riverside developed this poster. Email them at starvati@ucanr.edu or chowyang.lee@ucr.edu...

Multi-unit housing (MUH), such as apartment complexes and single-room occupancy (SRO) buildings, can harbor significant infestations of cockroaches, bed bugs, rodents, and other pests. Structural continuity (shared walls of adjacent units), budgetary constraints, poor maintenance and infrastructure, and cultural and social factors allow pests to infest and thrive in these environments.
Many of these pests threaten public health and wellbeing of the residents. For instance, German cockroaches (Blattella germanica) produce proteins that can be found in their feces and exoskeletons that, when dispersed into the air, can be inhaled, causing asthma in children.
Pest management is often conducted in response to...
