Caltech Reduces Coyote Encounters Through Campus Management Changes

The California Institute of Technology in Pasadena has successfully reduced coyote encounters on campus through a comprehensive management program that began last year.

Pasadena’s Public Health Department worked with Caltech starting in July 2023 to address coyote presence on the university grounds. The collaboration focused on removing attractants and food sources that draw the animals to campus areas.

Public Health Director Manuel Carmona and his department provided technical guidance to the university. Pasadena Humane also participated in the partnership effort.

The strategy centers on helping coyotes maintain their natural fear of humans. Officials say removing food sources prevents the animals from associating human activity with feeding opportunities.

Caltech implemented multiple changes across campus facilities. Workers now pick up fallen fruit and trim shrubbery that provides hiding places for coyotes.

The university repairs fences promptly and fills holes in soil where coyotes might establish dens. Staff members take out trash quickly and secure lids on garbage containers.

During events, cleanup happens immediately after gatherings on campus end. These measures have led to fewer coyote encounters, according to Caltech officials.

The Strategic Communications team created educational materials for the campus community. A wildlife page on the Caltech website features detailed coyote safety information.

Monthly email newsletters also reach students and staff with safety updates. Campus events allow community members to ask questions about coyote behavior and prevention strategies.

An online reporting system lets students and staff document negative coyote interactions. The university tracks these incidents to monitor program effectiveness.

Public health experts plan to return when fall classes begin in September and will join Caltech staff for educational discussions with students, faculty and local residents.

The sidewalk talks will cover coyote experiences and behavior education. Participants will learn additional tools for keeping the animals in their natural wild state.
