More yellow fever-carrying mosquitoes were found Thursdaynear a Menlo Park cemetery, prompting health officials to deploy traps and tell the public to "avoid mosquito bites."
Aedes aegypti mosquitoes, which can carry yellow fever and dengue fever, were eradicated in San Mateo after discovery in 1979 but have returned, according to the San Mateo County Mosquito and Vector Control District.
The first of 13 discoveries of mosquitoes or larvae was on January 22; more larvae near Holy Cross Cemetery were found Thursday, officials said.
Officials pledged to eradicate the bugs this time around. They are laying traps and telling the public to take care of standing water on their properties, according to a news release issued Friday.
Residents are instructed to "eliminate even the smallest amount of standing water," officials said.
The mosquito is not native to California.
No illnesses have been reported to date.
The public should also follow these directions:
- Apply insect repellents that contain DEET, picaridin, oil of lemon eucalyptus or IR 3535 and follow label instructions.
- Make sure that doors and windows have tight-fitting screens to keep out mosquitoes and repair or replace screens with tears or holes.
- Eliminate standing water and containers that can hold water from around the home.
- Report neglected swimming pools by calling San Mateo County Mosquito and Vector Control (650) 344-8592
- Wear long sleeve shirts and long pants when possible.
- Use mosquito netting over infant carriers, cribs and strollers.
