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...
Although all cockroaches in California are considered pests, the Turkestan cockroach is of particular concern. This cockroach has become increasingly common in California's residential outdoor areas because it has faster growth and higher reproduction rates compared to other cockroaches that live outdoors. Like other cockroaches, the Turkestan cockroach is considered both a nuisance and a public health issue.
What does the Turkestan cockroach look like?
Adult Turkestan cockroaches are about 1 inch in length. Females are slightly larger than males, dark-colored, flightless, and have distinct pale stripes right below their heads on their wing buds. Males are light brown with fully developed wings....
There are several flatheaded boring beetles in California, however only a few are of particular concern. The goldspotted oak borer (GSOB), Agrilus auroguttatus, is a metallic wood-boring beetle that threatens our native trees. Since it was introduced to Southern California on contaminated firewood in the early 2000s, this pest has caused extensive damage to woodlands and native oaks.
What does the goldspotted oak borer look like?
Adult GSOB are 0.4 inch long and 0.08 inch wide with bullet-shaped bodies. They are black with an iridescent green sheen and six distinct gold spots on their back.
What damage does the goldspotted oak borer cause?
