There are more than fifty species of mosquitoes in California, but only a few species are threats to humans. Most of us are acquainted with mosquito bites. Female mosquitoes use blood they draw from humans and other mammals in the development of their eggs. Unfortunately, some mosquitoes carry infectious diseases such as West Nile virus, which can be transmitted to the human's or mammal's bloodstream.
Community members can take steps to control mosquitoes and reduce the chance of being bitten. Mosquitoes breed and lay eggs in water, so it is important to remove standing water around your home and garden. Inspect your property for areas or objects that hold water and dump or drain standing water. Mosquitoes prefer stagnant, still water to lay their eggs so it is important to keep pools, fountains, and ponds in good working order. If you have a pond, consider mosquitofish or guppies. For bird baths and rain barrels, the UC IPM page on mosquitoes recommends Mosquito Dunks which contain a bacterial agent that kills only mosquito larvae and doesn't harm other insects, animals, or plants.
During the rainy season, look around your property every week and empty water from buckets, cans, pool covers, flowerpots, birdbaths, and other items. Throw away or cover up stored tires. Clean pet or livestock bowls weekly. Check for clogged rain gutters.
The UC IPM website has a video on YouTube that discusses mosquito control actions. To learn more about mosquito control, visit the Sacramento-Yolo Mosquito & Vector Control District.
For your own personal safety, ensure that window and door screens on your home are in good repair. Wear long sleeves, long pants, socks, and a hat outside when mosquitoes are present. Avoid being out of-doors at dawn or dusk as host seeking mosquitoes are most active during these times. Consider a mosquito repellant. The UC IPM website has another video on YouTube that discusses ways to protect yourself from mosquito bites.
