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).

Although they're small, cute, and furry, ground squirrels can be a real pest for California residents and gardeners. Found throughout California, burrowing ground squirrels cause damage to landscapes and structures while feeding on ornamental or food-bearing plants.
How can you get rid of ground squirrels?
There are several management options for ground squirrels. They might include:
- habitat modification
- fumigation and toxic baits
It's important to understand the life cycle and behavior of ground squirrels for.../h2>

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...

[From the Winter 2017 issue of the UC IPM Green Bulletin]
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.../span>
