Tick contact data is collected for the purposes of estimating tick populations only. This data is not used in predicting tick-borne disease risk. If you believe you may have been exposed to a tick-borne disease, please contact a medical professional. You can learn more about tick-borne diseases here.

To request tick identification or any other service from San Mateo County Mosquito and Vector Control District, please call (650) 344-8592 or use the Service Request Form. The District cannot respond to reports submitted through the tick report form.

Please include city, park or neighborhood, and trail name, if applicable. If you are not sure where you acquired the tick, please list areas you have recently visited.

If you are unsure when you acquired the tick, you may estimate or leave this field blank.

Please tell us when you discovered the tick, even if you are not sure when you acquired it.

When a tick bites, it attaches itself to the host’s skin. If you had to pull on the tick to remove it, it was attached. If the tick could be removed without pulling, it was not attached.

Please select species only if tick was positively identified; otherwise, select Species Unknown.

Please provide any other information you feel may be helpful.
