After weeks of rain, the weather forecast is starting to change, and that means it’s a good time to take a look around your yard for anything holding water to prevent mosquitoes now and later. With 23 confirmed species of mosquitoes in Contra Costa County, we already have some mosquitoes that are active, now, with more to follow as the seasons change. And since mosquitoes only need a small amount of water to develop from egg to biting adult in a matter of days, it’s important to dump out standing water and scrub each item as soon as the weather allows. The key to success is after you check the buckets and other containers, also look for toys, tools, and other places where you might not expect to find water.
Find It, Dump It and Scrub it
After invasive Aedes aegypti mosquitoes were found in Contra Costa County late last year, we now know it’s not enough to dump out rainwater alone — you also need to scrub the plant pots, dust bin, toys, and boat to make sure you remove any potential mosquito eggs that are stuck to each item just above the water line. Of course, if you find something disposable that is full of water, dump it out and seal it in a bag before placing it in the trash to prevent any more water from making contact with any potential mosquito eggs, allowing them to develop into adults.
