Protect yourself from mosquitoes and the diseases they transmit by practicing the District’s 7 Ds of mosquito prevention.

DRAIN any standing water that may produce mosquitoes.

DAWN and DUSK are times to avoid being outside. This is when mosquitoes are most active.

DRESS appropriately by wearing long sleeves and pants when outdoors.

DEFEND yourself against mosquitoes by using an effective insect repellent, such as DEET, Picaridin or Oil of Lemon Eucalyptus.
Make sure you follow label directions.

DOOR and window screens should be in good working condition. This will prevent mosquitoes from entering your home.

DISTRICT personnel are available to address mosquito problems you may be experiencing (available to Contra Costa county residents only). Please call 925-685-9301 for more information.
