Pest Management – Ground Squirrels

San Mateo County Parks has posted an announcement that Flood Park will be closed several times in the next 4 months to address the over population of ground squirrels in the park. You can get all of the details on the County Parks FAQ webpage for this pest management process.

In the coming months, Flood County Park will be closed the following dates while a pest management plan is implemented to reduce the large population of ground squirrels that are damaging the park’s natural resources and facilities: 

  • November 9, 10, 11
  • December 14, 15, 16
  • January 11, 12, 13
  • February 15, 16, 17

Ground squirrels can be found throughout open, grassy fields in rural and urban areas and are different from tree squirrels. While tree squirrels inhabit trees, ground squirrels create underground burrows usually around 4 inches in diameter and between 5 and 30 feet long where they rest, store food and raise young.

Oversized populations of ground squirrels cause damage to facilities and walking paths and to seedling plants and high value trees by damaging bark and root systems. Ground squirrels, like other rodents, can also carry fleas, mites, and diseases.
