In September 2020, Governor Gavin Newsom signed into law Assembly Bill 1788, which prohibits almost all uses of second-generation anticoagulant rodenticides (SGARs) statewide. Rodenticide products containing brodifacoum, bromadiolone, difenacoum, or difethialone have been restricted materials in California since 2014. They are only available for use by licensed pest control applicators.
The new restrictions are intended to reduce potential poisoning of nontarget wildlife. According to the text of the bill, scientific research and state studies have found rodenticides in over 75 percent of animals tested. From 2014 through 2018, the Department of Fish and Wildlife found SGARs...
Rodent Awareness Week (October 18-24) is a campaign created by the National Pest Management Association to educate the public about the potential harm associated with rats and mice. In addition to damage to structures and property, rodents can transmit disease to other animals and humans.

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.

Rodenticides are essential tools in the IPM toolbox for rodent management. Exclusion and cultural practices, such as landscape management and sanitation, are also very important tools that should be considered when managing rodent populations. However, persistent and chronic infestations often require the use of rodenticides.
Rats (Fig. 1) and mice are vectors of disease such as plague, leptospirosis, and salmonellosis. Commensal rodents are also associated with the onset of...

[From the May 2017 issue of the UC IPM Retail Newsletter]
Keeping backyard chickens is becoming increasingly popular in residential areas around California. Your store may be selling pre-made chicken coops, feed, or other accessories, or you may be getting questions about rodent pests in chicken houses.
Chicken coops are sometimes associated with mild to serious rodent infestations. Rodents, such as rats and house mice, are not only predators of chickens and eggs, they can carry and transmit many diseases to both chickens and humans. For rodents, as well as most pests in and around the home and garden,...
