Look for Standing Water and Dump it Out
Mosquitoes lay their eggs in or near water. Once in water, the eggs can develop into adult mosquitoes in a matter of days. The warmer the weather, the faster some mosquitoes grow from egg to adult. Female mosquitoes are the ones who can bite people and can spread the causative agents for mosquito-borne disease. That is why dumping out rainwater is so important. By dumping out sources of water, you take away places where mosquitoes can grow into biting adults.
With this week's rain followed by sunny days in the forecast, the Contra Costa Mosquito & Vector Control District (District) is asking county residents to walk around your property and dump out any amount of standing water, because even a small amount of water can produce mosquitoes.
