Do You Have Any of These Mosquito Sources?
These are not your common Southern house mosquitoes. Invasive, black-and-white Aedes mosquitoes thrive in your communities. This is because they primarily bite humans. In addition, people provide these mosquitoes perfect "homes" or sources in their backyards and patios.
What's the big deal about Aedes mosquitoes?
They are efficient at transmitting (vectoring) several human arboviruses including chikungunya, dengue, yellow fever, and Zika. In recent U.S. history, Aedes mosquitoes were responsible for Zika outbreaks in Florida, Texas, and Hawaii. If you travel (Europe, Asia and South America), please be aware you could be a carrier of diseases and not know it!
How Do I Know They're Infesting My Home?
- You or a family member receive mosquito bites during the day.
- Mosquitoes are biting indoors (office, home, garage, etc.)
- You notice black-and-white adult mosquitoes smaller than a pinky nail.
How do I keep them out of my home?
First step for Vector Control professionals: Tip 'n Toss! Tip out any stagnant water, and toss out unused containers. All mosquitoes require stagnant water to lay their eggs and grow. Eliminating stagnant water around your home prevents mosquitoes from developing in the first place. This is called “source reduction.” If done weekly, source reduction is much more effective at eliminating mosquitoes than using any pesticides.
Did You Know...?
Most of the invasive Aedes activity in a community comes from residential backyards. In order to reduce the population and control the nuisance, residents must take responsibility for their own yards and work with their neighbors to do the same.
Talk to your neighbors and make mosquito source reduction a part of your weekly routine. Together we can keep a healthier San Gabriel Valley.
How did invasive Aedes got here?
Unfortunately, in 2011 our staff identified a thriving population of Aedes albopictus in the city of El Monte. The mosquito was able to find suitable micro-habitats in flower pots, planters, and watered vegetation surrounding people’s homes. In subsequent years, Aedes aegypti and Aedes notoscriptus were also identified in the Los Angeles area. Reports started coming in of localized infestations up and down the entire state of California. The statewide infestation of invasive Aedes is due to multiple introductions from shipments of goods contaminated with eggs, as well people moving with plants and containers contaminated with eggs.
