Catching rainwater now to use on plants later is a great idea. Giving mosquitoes new places to lay their eggs is not. Before you put a bucket or container out to catch the plentiful rain, think about this: mosquitoes need very little water in which to lay up to 400 eggs. And late fall and winter is the time of year when some mosquitoes thrive. Seven of the 23 different types of mosquitoes in Contra Costa County are present in fall and two make their appearance in winter. Indeed, mosquitoes are still around and they can bite you.
To prevent mosquitoes during the rainy season, frequently check your property. Make sure you don't have tools, toys or containers collecting rainwater. If you put up holiday lights, give your gutters a sweep to make sure leaves or branches aren't stopping water from draining completely. And if you have a swimming pool you are not maintaining over the winter, visit our facility to get free mosquito-eating fish. Even into December, neglected swimming pools are producing thousands of mosquitoes - the type that can transmit West Nile virus.
But saving water is still a great idea. Many garden stores sell rain barrels designed to deny mosquitoes access, but you can alsomake your own mosquito-proof rain barrel by using a trash can, window screening and a couple bungee cords. Here's a great example from our friends at the Orange County Vector Control District on how to save rainwater that denies mosquitoes a home to thrive.
