Protect our Children and Pets from Toxic Pesticides in Walnut Creek, CA Parks

Tell the City of Walnut Creek that you appreciate their excellent track record on many environmental issues such as addressing climate change. However, the usage of toxic pesticides applied regularly at the following public areas must stop:

Heather Farm, Heather Farm Dog Park, Heather Farm Equestrian Center, Heather Farm baseball fields, Larkey Park, Civic Park, Rudgear soccer and softball fields, Castle Rock Park, Diablo Shadows, Arbolado Park, Alma Park, Walden Park, Tice Valley Park, El Divisadero Parks, Canal Trails, Jones Road, Marshal Road, Camino Verde, Heritage Court, Open Space trail heads (Lime Ridge, Shell Ridge, Acalanes Ridge, Borges Ranch, Howe Homestead, Sugarloaf), and our baseball fields where children and pets play!

These pesticide products (Speedzone, Ranger-Pro, Barricade, Kaput-D Gopher Bait, Glyphosate Pro 4) contain 2,4-D, mecoprop-p, prodiamine, glyphosate, and diphacinone, which are known human developmental toxins, hormone disruptors, cancer-causing chemicals, hazardous air pollutants and also listed as endangering wildlife and illegal to use around protected or endangered animals.

If illegal to use near protected and endangered animals, shouldn’t our kids and pets be protected from these products also?

Rodenticides are applied in the parks that risk secondary poisonings and dead owls have already been collected in multiple locations by Audubon Society members. Many municipalities have stopped using rodenticides and only use traps or CO2 asphyxiation, that are more humane, effective and economically feasible.

Honey bee colonies are being jeopardized by the spraying of “neonicotinoid” insecticides onto trees. These chemicals are banned in many countries and many municipalities in the U.S. have adopted resolutions to not use neonicotinoids in order to prevent colony collapse disorder. There are many effective alternatives to addressing insect infestations that do not involve using this very toxic family of chemicals that risk our food production, as honeybees are integral in the pollination of many of our crops.

Residents of Walnut Creek who care about public health, health of their pets,wildlife and the environment urge the City Council to schedule a "Special Meeting" solely to address this issue with Parents for a Safer Environment immediately and update the City’s IPM Program with the following resolutions:


  1. Cease all pesticide spraying where there is potential access by people, pets, wildlife, or where there may be drift or runoff into storm drains or creeks by irrigation or rain storms.  Implement cultural and biological methods used successfully by other municipalities.
  2. Cease all rodenticide usage and use only traps or better yet, CO2 asphyxiation with all proper evaluation of burrows to protect non-target species.
  3. When pesticides are applied, post 72 hours prior to any pesticide spraying online as well as onsite so that people can make a choice to enter treated areas with their children and pets. And keep posted until the half-life of the products has passed. Samples of posting are on the California Department of Pesticide Regulation and School IPM webpage.
  4. Provide monthly pesticide use reports for all treatments in the city maintained grounds on a designated webpage to provide transparency. The information should include all the data provided to the CA Dept of Pesticide Regulation AND the locations of treatments, and the name of the target pest species.
  5. Demonstrate least toxic alternative pest control methods were attempted and documented prior to using toxic pesticides. This data can also be placed on the designated webpage.
  6. Track each distinct pest control program and demonstrate in an annual report and presentation to the City Council how good-faith efforts are being made to phase out pesticides and utilize least toxic alternatives that are working for other municipalities.
  7. Adopt a list of approved, limited, and restricted pesticide categories so that staff will not make the mistake of using unnecessarily hazardous chemicals in areas where people, pets, wildlife, and the environment are likely exposed.  

Marin County and most of its cities have successfully adopted either pesticide-free zones or written IPM Policies with an approved/limited/restricted list and implemented them with great success.  

Parents for a Safer Environment presented the analysis of the pesticides in question to the City Council on September 15, 2015. The City has offered to learn more on December 14th and offered 15 minutes to present to the Parks, Recreation, and Open Space Commission. We, the Parents and Facility Users of Walnut Creek, urge that a "Special Meeting" of the City Council be scheduled immediately to address the above resolutions so that the City can rectify the unnecessary risks being imposed to the inhabitants and users of the city’s facilities from unnecessary pesticides before the end of the year.   

Please e-mail or to get involved with our grassroots campaign to reduce the risks to cancer, autoimmune diseases, and other illnesses from starting in the first place in the city we love and call home.
