Animals & Pests

Animal Control

Animal control and sheltering services are provided through an agreement with the Contra Costa County Animal Service Department. The CCC Animal Services has two animal shelters, one in Martinez and one in Pinole. The department handles lost and found animals, licensing, adoptions and emergency pet services. In addition, they offer numerous field services such as investigating claims of animal cruelty, picking up injured animals, and impounding stray animals.

Mosquito and Vector Control

Contra Costa County maintains a special district for mosquito and vector control. The Contra Costa Mosquito and Vector Control District’s primary goal is to protect the public’s health by controlling local pests, including rats, skunks, ticks, yellowjackets, bees and mosquitoes and providing public awareness and prevention assistance to Contra Costa County residents.

West Nile Virus

West Nile virus is a viral disease of birds that is transmitted from bird to bird by mosquitoes. It can occasionally cause meningoencephalitis (inflammation of the brain and spinal cord) in susceptible people or animals that are bitten by infected mosquitoes. Most people and animals recover from the virus, but those with weakened immune systems are more likely to develop serious symptoms possibly resulting in death. Visit the the Contra Costa Mosquito and Vector Control’s website for more information on this serious virus.


The City of Hercules encourages residents to be responsible pet owners. Pet ownership is a big commitment and one that should not be taken lightly. Being a responsible pet owner includes not only taking care of your own pet but also being considerate to your neighbors, local businesses, and the community.

The City of Hercules, along with other cities and towns within Contra Costa County, has adopted the County Animal Control Ordinance. The County Animal Control Ordinance regulates the ownership and possession of animals for all of Contra Costa County. It includes a section on dangerous animals as well as the penalties or fines for each violation.

All dogs over 4 months of age are required to be licensed according to the County Animal Control Ordinance and are processed by the Contra Costa Animal Services Department. Before a license will be issued, a rabies vaccination certificate is required. In addition, the County offers discounts to pet owners if your pet has been spayed or neutered. The County Animal Control Ordinance provides free licensing of certain pets including guide/service dogs, police dogs, or pets whose owners are over the age of 65.

You can purchase a pet license online at the Contra Costa County Animal Services webpage or download the pet license application (PDF).
