Wet weather brings mosquito concerns to California.

California's wet winter could lead to an abundance of mosquitoes, as standing water from the storms creates breeding grounds for the insects. Experts advise taking action to prevent mosquito infestations, such as clearing away standing water on properties and adding screens to windows. Certain species of mosquitoes can lay eggs that are viable for more than six months, and can develop as soon as water returns. Mosquito control agencies are working with residents to monitor breeding sites and prevent the spread of diseases like West Nile virus.
