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...

It is important for food-safety reasons to manage rats in school and community gardens. Rats and other wildlife can carry a number of diseases that can be deposited in the form of urine and feces on fruit, vegetables, and in the soil.

Managing rodents in and around school and community gardens can be difficult. One of the easiest ways to keep many rodents at bay is to remove...

Rodenticides continue to come under scrutiny in California due to issues surrounding the potential for nontarget injury to wildlife and pets. While California already has the strictest rodenticide laws and regulations in the country, there have been recent calls to ban all rodenticide applications in the state. Several Assembly Bills (AB 2596, AB 1687, and AB 2422) have been introduced proposing either bans or major restrictions on rodenticide applications.
Anticoagulant rodenticides have been detected in many species of wildlife worldwide; yet the origins, exposure pathways, and effects of these exposures are not well understood. The origins of these rodenticide exposures from point of application to point of...

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.

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,.../span>
