How the District Continues to Protect Public Health
A District Employee Arrives for a Residential Mosquito Inspection
With this week's order from the acting Contra Costa County Health Director that county residents are to shelter at their place of residence except to provide or receive certain essential services, many folks are wondering, what those essential services might be.

The Contra Costa Mosquito & Vector Control District is a public health agency dedicated to protecting the community from mosquitoes and other vectors of disease and as such provides essential services to the people of Contra Costa County. 

At this time, we are continuing to provide our essential services of protecting public health by working to prevent vector-borne disease in Contra Costa County; however, until further notice, the District building is no longer open to the publicIn addition, the District will be making the following changes to our services in an effort to reduce the risk of COVID-19 transmission:
  • District employees will continue to conduct exterior inspections for mosquitoes, rats, mice, skunks, ground-nesting yellowjackets and bees.
  • District employees will not enter, nor provide an interior inspection of a home or other structure for any of the vectors for which the District provides service. 
  • Wait times for response to requests for service for mosquitoes, rats, mice, skunks, ground-nesting yellowjackets and bees may increase as a result of changing workloads.  
  • In-person mosquitofish pick up is temporarily discontinued. Please make requests for mosquitofish through the District voicemail at 925-685-9301 or online. Once a request has been made, a District employee will inspect the property and if mosquitofish are necessary and appropriate, the employee will place the mosquitofish in the Contra Costa County water feature associated with the request. 
  • In-person Tick and Pest Identification services are temporarily unavailable; however, residents may fill out a form online and mail a tick or other pest sample to the District. 
    • After carefully removing a tick from a family member, including the family dog, place the tick in a ZiplocĀ® bag with a damp cotton ball. Place the bag in an envelope. Next, fill out this online form. A copy of your submission will be emailed to you. Please print the form and place it in the envelope along with the baggie carrying the tick or other pest and mail it to the District. If the tick turns out to be the one species among the four that commonly bite people here in Contra Costa County that can transmit Lyme disease, a District employee will notify the person who mailed the tick to the District. 
In addition, with an emphasis on increasing personal protection for both District employees and members of the public: 
  • District employees will practice social distancing when providing all on-site inspections. Social distancing is defined by the Centers for Disease Control and Prevention (CDC) as maintaining distance (approximately 6 feet or 2 meters) from others when possible. 
  • District employees will use increased hand hygiene by washing  their hands in between arriving for each on-site inspection and will no longer shake hands. 
How Contra Costa County Residents can Help the District 

In spite of all of the changes to District services in response to COVID-19, the District remains  committed to reducing the risk of mosquitoes and their associated diseases in Contra Costa County.  We also need your help. 

As the First Day of Spring is just days away, now is the time to:
  • Eliminate all sources of standing water on your property, including in flower pots, old tires, buckets, pet dishes and trash cans.
  • Clean rain gutters clogged with leaves.
  • Repair leaking faucets and broken sprinklers.
  • Install screens on windows and doors and keep them in good repair.
  • Dress in loose-fitting long sleeves and pants.
  • Apply insect repellent containing EPA-registered active ingredients, including DEET, picaradin, oil of lemon eucalyptus, or IR3535, according to label instructions. Repellents keep mosquitoes from biting. 
If, in spite of your efforts, you still find you find you are being bitten by mosquitoes while on your property, please swat one of the mosquitoes and stick it in a clear plastic bag to create a mosquito sample , and then contact the District to request the District's mosquito service. We need the sample to identify the species of mosquito that is biting you and to help us direct our surveillance and control efforts. 

Thank you for your help in reducing the risk of mosquitoes on your own property and thank you for your understanding as the District makes these important alterations to our services as we all do our part to reduce the risk of both vector-borne disease and COVID-19.
