You may not think about rodents such as rats, mice, or gophers until they become a pest around your home. Because rodents can be major pests in and around homes, gardens, landscapes, restaurants, and other buildings, each year pest control experts “celebrate” Rodent Awareness Week. Rodent Awareness Week (October 16-22) is an annual campaign created by the National Pest Management Association to educate the public about the potential harm associated with rats and mice. In addition to damaging structures and property, rodents can transmit diseases to humans and other animals. During the fall and winter months, rodents will seek food and shelter in...

Trapping is the safest and most effective method for controlling rats and mice in and around homes, garages, and other structures. Rodents that live in close association with humans are called commensal rodents. Rats and mice are the most frequently encountered commensal rodents in California.
Selecting the correct trap
Before trapping, make sure you know what rodent pest you have. It is a very common mistake to select the wrong size trap when you have not yet determined whether you have mice or rats (and the correctly identified rat species).
You will not catch a rat with a mouse trap, and you will not catch a mouse with a rat trap. To determine...

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...
