–  “Why California’s Ban on Retail Sale of Toxic Rat Poisons Isn’t Enough”
Very important comment on the new California Department of Pesticide Regulation rules banning consumer purchase and use of 2nd generation anticoagulant rodenticides by Lisa Viani of Raptors are the Solution (see above for her websites).

–  “The Devil is in the D-Con”
After the maker of D-Con Reckitt Benckiser’s requested injunction against the July 1, 2014 start date for the CDPR’s new rules was turned down, they threw in the towel also in their fight against the EPA’s national rules (which are weaker than California’s). Here is an article explaining why this is only a partial victory.– Malibu Times article, July 24, 2014, on Poison Free Malibu’s recent activities:

– “MROSD concerned about rodenticide’s effect on local bobcats” from the Coastsider, March 31, 2014, a local newspaper for coast north of Santa Cruz. The mange epidemic has reached there and bobcats are disappearing from where they were once abundant.

-“Poison kills more than the intended animal” from the Lake Tahoe News, January 9, 2014. Hits the nail on the head on how homeowners must be conscious of what the poisons are doing.

– “Rodenticides, lack of space threaten local wildlife” from the Malibu Times, January 2, 2013. Threats to mountain lions, bobcats, and other predators in Malibu area.

Steve Scauzillo is a great journalist on the environment for the Los Angeles News Group. Mentions Malibu and Whittier, and the hope that the model of Malibu will spread the work throughout Los Angeles County.
– “Cities, EPA moving to curb use of rat poison linked to bobcat deaths” from the San Gabriel Valley Tribune from July 15, 2013.

Linda Richards is another great journalist, for the Redlands Daily Facts.
– “Rodent poisons and our ailing wildlife” April 9, 2013.
– “Rodent Poison in the Garden Can Harm Wildlife” August 19, 2013.
– “Rodent Poisons: What Communities are Doing” October 14, 2013.

Rodent related disease references

Articles from the Center for Disease Control.

In this page, are the following articles.

Hantavirus treatment

Hantavirus happened in Yosemite in August 2012. See:
The Story Behind Last Summer’s Hantavirus Outbreak
It is caused by unsanitary environments where mice waste accumulates.
Unfortunately, it happened because in 2009 cabins in Yosemite were
renovated in such a way to promote it. The solution was tearing down the cabins and reconstructing them, so this could not happen. NO POISON WAS USED and would not have been effective.

Hemorrhagic Fever with Renal Syndrome

Not found in the United States. 

Lassa fever

Limited to West Africa.


Leptospirosis is treated with antibiotics.

Lymphocytic choriomeningitis factsheet

Infrequent recognition and diagnosis, and historic underreporting of LCM, have limited scientists’ ability to estimate incidence rates and prevalence of disease among humans.

Omsk Hemorrhagic Fever

OHF occurs in the western Siberia regions of Omsk, Novosibirsk, Kurgan and Tyumen.

Plague statistics

Concern about the plague from fleas on squirrels is frequently presented as
a motivation for concern about squirrel, and other rodent, populations.
Despite the emotional reaction associated with the plague, the threat in Los
Angeles County is insignificant. The plague is treatable with antibiotics and
the epidemics of the past, which are the original source of the fearful
reactions, are virtually impossible.

The Center for Disease Control reports the number of human plague
infections in the ENTIRE United States by year at
The numbers of infections from 2010 to 2016 were 2,3,4,4,10,16,4!
The numbers of deaths in those years were 0, 0, 0, 1, 0, 4, 0.
In Los Angeles County WHERE WE ARE it is even rarer. The most recent
case was 2006, see
It was traced to a rabbit brought in from OUTSIDE Los Angeles (Kern
County) by a hunter, and the hunter’s wife was infected, treated, and
Previous to that was in 1984 (!) when a veterinarian caught the plague from
a cat. Shouldn’t therefore we be killing all the rabbits and cats first for such
a minuscule rate of occurrence?

Rat Bite Fever

Rare in the United States. Accurate data about incidence rates are unavailable because the disease may not be reportable to state health departments. Since RBF is not a nationally notifiable disease, trends in disease incidence in the U.S. are not available. Recent case reports have highlighted the potential risk for RBF among persons having contact with rodents at home or in the workplace.


Controllable by handwashing.

South American Arenavirus

Occurs only in Argentina, Bolivia, Venezuela, and Brazil
