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...
Coyote sightings are on the rise in San Francisco, even taking naps in patches of green spaces in the city, reported Uma Chrobak in Popular Science. However, it is unlikely they indicate a change in wildlife behavior, said UC Cooperative Extension human-wildlife interactions advisor Niamh Quinn.
Officials believe the increased sightings may have more to do with a change in human behavior. Many people are at home and bored, so they may staring out the window and going on more walks in their neighborhoods.
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).

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. Rats can also directly damage fruit and vegetables by consuming the produce entirely or by gnawing on parts of it and making it unfit for human consumption. Norway rats create burrows that can compromise beds and root systems. While rats can also chew on drip irrigation and damage the tubes, it is more common for some other wildlife species to chew on these.
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...
