Description: Provides identification of ticks and biting or stinging pest samples submitted by Contra Costa County residents. Contra Costa County Residents may send a tick or pest sample to the District’s office at 155 Mason Circle, Concord, CA 94520 or drop the sample off in person. The District’s laboratory staff will identify the tick or other biting or stinging insect and let the resident know the results. If the pest is a tick and the resident wishes to have the tick tested for Lyme disease, the District can provide a list of local laboratories that will conduct Lyme disease testing. Since April 1, 2010, the District no longer tests ticks for Lyme disease that are brought in by the public.
