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>

A mountain lion entered an Orange County corral last week where nine pygmy goats belonging to members of the Trabuco Trailblazers 4-H Club were housed. Only one goat survived the encounter.

“We know that this is happening all over California,” Quinn said. “Sixty to 85 percent of depredation permits are issued to hobby farmers and ranchers who seek to kill wild animals that threaten their livestock.”
The loss of the goats is a sad reminder for Californians to be aware of wildlife predators in their areas and make sure that livestock enclosures are secure against...
In October 2016, the University of California Cooperative Extension, Orange County, in association with the Pest Control Operators of California, Target Specialty Products, and Univar, hosted a three-day West Coast Rodent Academy for pest management professionals. The event was held at University of California's Agricultural and Natural Resources South Coast Research and Extension Center in Irvine, CA.
At the academy, participants learned about rodent identification, rodent disease, sanitation, monitoring, trapping, and urban rodent surveys. Participants were provided with opportunities to learn about good environmental stewardship practices and provided with updates on the laws and regulations concerning trapping and the use of...

It is unclear whether this is due to territoriality issues, increased human conflict due to increased coyote activity, increases in energy demands on coyotes when...
