Cockroaches, or roaches, are probably some of the least welcome insects people encounter in their homes, kitchens, offices, restaurants, or landscapes. Indoor cockroaches can create significant public health problems by contaminating food and producing allergens.
To help manage both indoor and outdoor cockroaches, UC Cooperative Extension IPM Advisor Andrew Sutherland and UC Riverside entomologists Dong-Hwan Choe and Michael Rust tackle the challenge of cockroach management in the newly revised Pest Notes: Cockroaches.

Two species of Blatta cockroaches can be common peridomestic pests in California, including the familiar oriental cockroach (B. orientalis) and a relative newcomer, the Turkestan cockroach (B. lateralis, Figure 1). Adults of both species are large (usually one inch or more in length) and conspicuous insects that harbor and breed outdoors within moist crevices around structures, such as subsurface utility ports, voids associated with concrete expansion joints, and soil cracks formed at junctions of landscape and hardscape elements (Figure 2).
From these harborage sites, cockroaches venture out at night to feed on a wide variety of...
While working outside, gardeners and farmers may discover pest problems they need to answer quickly. To meet this need, the University of California Division of Agriculture and Natural Resources has recently published the Vegetable Pest Identification for Gardens and Small Farms card set.
This travel-sized guide is a convenient and quick way to keep a pest management reference in your pocket. The set of 53 full-color cards contains photos and information about common insect and mite pests as well as plant diseases, nematodes, abiotic disorders, weeds, and vertebrate pests. The cards focus on sustainable pest management for vegetables, melons,...

Don't let the bed bugs bite? That's easier said than done, it seems. Bed bugs (Figure 1) continue to be important household pests globally, driving a growing sector of the pest control industry. Professionals have access to effective insecticides and specialized techniques, such as heat treatments, to control bed bug infestations. These services, however, can be expensive: a recent survey revealed the average cost of professional insecticide treatments and heat treatments to be $425 and $1,400,...

Survey of professional bed bug management in multi-unit housing
Bed bug management is especially challenging in multi-unit housing (MUH) situations such as public and low-income apartment buildings. In these environments, high resident turnover, lack of resources, ease of bed bug dispersal, and communication barriers may all contribute to chronic infestations.
Researchers and policymakers recognize the need to address this challenging...
