Since the Contra Costa Mosquito & Vector Control District office closed to the public due to the COVID-19 pandemic, residents seeking mosquitofish could not pick up fish in person. The District’s mosquitofish service changed to allow residents to request mosquitofish as they have with other District services. Now, as we all slowly move toward life in the “new normal”, one thing that is staying the same, and until further notice, the District remains closed to the public and in-person fish pick up remains unavailable.
At this time, the only way Contra Costa County residents may receive mosquitofish from the District is by requesting mosquitofish here or by calling the District at 925-685-9301.
Upon receiving your request for mosquitofish:
- A District employee will follow up with you and make an appointment for an inspection.
- During the inspection, the District employee will determine if the water feature is an appropriate location for the fish.
- If the location is appropriate for mosquitofish, the District employee will place fish in the water feature.
- If, for example, the water feature is found to be producing more mosquito larvae than the fish can initially handle, the District employee will provide assistance and advice on the appropriate action to mitigate the mosquito issue.
Please do not visit the District to pick up mosquitofish. We’ll bring the mosquitofish to you.
