Integrated Pest Management (IPM) is a decision-making process to determine pest levels and tolerance thresholds and combines biological, cultural, physical, and chemical tools to minimize health, environmental, and financial risks. The method uses extensive knowledge about pests, such as infestation thresholds, life histories, environmental requirements, and natural enemies to complement and facilitate biological and other natural control of pests.

It coordinates the use of pest biology, environmental information, and available technology to prevent unacceptable levels of pest damage by the most economical means, while posing the least possible risk to people, property, resources, and the environment.

2017 Integrated Pest Management Plan Update

On November 7, 2017, the City Council approved a significant policy and procedures update for the city's Integrated Pest Management Program. The plan was developed with the guidance of public input, through community workshops, and meetings with the Natural Resource Commission (NRC) Hazardous Materials Subcommittee, as well as the Open Space and Habitat Commission, the Tree Commission, and the Recreation and Parks Commission.

Integrated Pest Management

Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.

The IPM approach can be applied to both agricultural and non-agricultural settings, such as the home, garden, and workplace. IPM takes advantage of all appropriate pest management options including, but not limited to, the judicious use of pesticides. In contrast, organic food production applies many of the same concepts as IPM but limits the use of pesticides to those that are produced from natural sources, a

A video from the National Pest Management Association


The City's Integrated Pest Management Coordinator conducted an IPM workshop in May 2015. The following two videos can help you learn about IPM - an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. These videos also focus on the usual pests found in Davis homes and gardens.



Integrated Pest Management Policy and Annual Report

Pesticide Hazard and Exposure Reduction Zone Maps

The PHAER (Pesticide Hazard and Exposure Reduction) Zone System seeks ways to measure progress towards risk reduction goals, it allows grounds managers needed flexibility in their management options, and it informs the community about the general level of pesticide hazard that could be present on a site-by-site basis.

The PHAER Zone System establishes management zones on each site based upon the unique risk reduction goals of individual jurisdictions. These zones are designated as Green, Yellow, and Special Circumstance Zones, with Green Zones providing the lowest potential for pesticide hazard and exposure. Each Zone has a corresponding pesticide list determined by existing toxicological data.

Pesticide Information Hotline

Due to public desire to know where and what pesticides are being applied in and along our parks, greenbelts, and miscellaneous landscaped areas that people are most likely to enter, we have established a "hotline" to provide this information. As always, no pesticide applications take place within playground areas.

The hotline number is (530) 757-5621.

The Hotline will provide the caller with information on contacting the IPM specialist who can provide the locations and pesticides which are anticipated to be applied. Because the weather conditions (e.g. windy or rainy) are not known at the time an application is planned for the following workday, the hotline information provides only anticipated applications.

The City of Davis Integrated Pest Management Program utilizes the PHAER (Pesticide Hazard and Exposure Reduction) Zone System.

Notice shall be provided to those desiring to stay clear of the entry area of an application site. The Parks division will provide visible notice by posting "caution" signs near the application areas which people are most likely to enter.

If you have further questions about the Pesticide Information Hotline, please contact the City of Davis Public Works Department, at (530) 757-5686.
