SACRAMENTO REGION, CA (MPG) - The recent rain has left behind stagnant water. Since temperatures are expected to increase over the next few days, this can create the perfect combination for mosquitoes to breed, according to the Sacramento-Yolo Mosquito and Vector Control District on Feb. 20.

The Sacramento-Yolo Mosquito and Vector Control District reminds the public to “drain after the rain” to prevent mosquitoes from breeding. 

“Mosquitoes complete their life cycle much faster in warm weather. We encourage all residents to do their part and help us drain standing water from common backyard sources such as buckets, flowerpots, bird baths, old tires and other small containers that may breed mosquitoes. Eliminating mosquito breeding grounds now will significantly reduce their population later in the season,” said district manager Gary Goodman.  

This is particularly important for preventing the spread of invasive mosquitoes Aedes aegypti and Aedes albopictus, which continue to expand across both counties. Invasive mosquitoes are a public health threat because they are capable of transmitting debilitating diseases such as Zika, dengue and chikungunya. Invasive mosquitoes were detected for the first time within district boundaries in 2019 and since then have been spreading quickly.

As spring begins next month and warm, dry weather sets in, mosquitoes are likely to keep thriving. Although it's still early in the year, it’s crucial for the public to stay protected against mosquitoes and diseases such as West Nile virus.

“The best protection against mosquitoes is to wear an effective repellent when spending time outdoors” Goodman said. 

To report any stagnant water, mosquito breeding problems or request a free home-service inspection including mosquitofish for your pond/fountain, call 1-800-429-1022 or fill out a free service request online at FIGHTtheBITE.net.

The Sacramento-Yolo Mosquito and Vector Control District provides year-round mosquito and vector control services in Sacramento and Yolo counties. The main goal for the district is to protect public health by preventing the transmission of diseases and improving the quality of life for all residents.
