Mosquitoes carrying West Nile Virus (WNV) were recently found in Boston and Weymouth. Last year, over 5% of the mosquitoes tested in Massachusetts carried WNV, according to the Massachusetts Department of Public Health (MDPH).
Culex mosquitoes are the primary carriers of WNV, which humans can catch from the bite of an infected mosquito.
These mosquitoes are common throughout the state, in cities as well as suburbs and rural areas. Culex mosquitoes prefer to lay their eggs in catchbasins, clogged rain gutters, unused tires, buckets and other water holding containers.
Eliminate their breeding places by:
- Cleaning rain gutters and drains
- Emptying unused flowerpots, wading pools and other sources of standing water.
- Changing the water in birdbaths frequently
Don't Get Bitten
- Culex mosquitoes are most active between dusk and dawn - consider scheduling outdoor activities for other times
- Make sure your window and door screens are intact.
- Wear long sleeves, long pants and socks - these can be treated with permethrin to further protect you
- Use insect repellant containing DEET, picaridin, or oil of lemon eucalyptus according to directions
