NewsInvasive Mosquito Alert (Yellow Fever)
Invasive Mosquito Alert: Aedes aegypti Detected in Chino Hills Aug 22 – The West Valley Mosquito and Vector Control District has detected the presence of Aedes aegypti, commonly known as the yellow fever mosquito, in Chino Hills. Enhanced surveillance in the area was triggered on August 21st in response to a resident complaint of daytime-biting mosquitoes. The traps were located near Slate Drive and Agate Road.
The yellow fever mosquito will bite in the daytime and the evening They are small mosquitoes that have white bands on its legs, and prefer to lay eggs in man-made receptacles such as tires, fountains, potted plants, and birdbaths. Aedes lay their eggs singly on the sides of containers, usually just above the water line, and can withstand drying and heat for up to 12 months. When the eggs meet with water, they activate and hatch. Aedes may lay eggs and develop indoors as well as outdoors. Aedes aegypti are an important species because they are known transmitters of West Nile virus, Dengue, and Zika virus. Because they are new to our environment and with their unique biting and egg laying habits, yellow fever mosquitoes have the potential to spread rapidly and introduce previously unseen human disease to our area.
Residents can help combat this invasive mosquito by dumping all standing water found in items such as birdbaths, trash cans, and flowerpots, to frequently change the water in pet’s dishes and to ensure pools and spas are properly maintained. Containers that were holding water should also be cleaned and scrubbed thoroughly to remove any eggs glued to the sides.
To prevent mosquito bites, ensure that window screens are in good repair, and to use an effective mosquito repellent when outdoors. The Centers for Disease Control recommends using a repellent containing Picaridin, DEET, Oil of Lemon Eucalyptus, or IR3535. Residents are also urged to report green pools, standing water, or day-biting mosquito problems to the District at 909-635-0307 or online at www.wvmvcd.org.
