The Health Department would like the public to know that the catch basins in town were treated this spring with ALTOSID XR Briquettes supplied by the Wayland Board of Health and distributed by the East Middlesex Mosquito Control Project.
The treated catch basins are marked with a white paint dot. The Health Department requests that the public check catch basins in their neighborhoods. If your catch basin does not have a white paint mark, please contact the Health Department at 508-358-3617 and give us the exact location of the catch basin.
This catch basin treatment is to reduce the number of the culex mosquitoes, which are known to reproduce in a catch basin type of environment. West Nile virus (WNV) is a mosquito-carried virus that can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis. WNV is most commonly spread to people through the bite of an infected mosquito. The culex species are also known as “bridge” vectors that will feed on birds and people. At this time of year, birds could be infected with West Nile Virus, and the catch basin treatment decreases the risk of West Nile Virus infecting people.
At this time, the Town of Wayland is classified by the state to be an area of low risk for mosquito-born illness as of 07/16/12. However, it is a good time to review certain actions that residents should take related to WNV. We have recently been advised by the Eastern Middlesex Mosquito Control Project that weather conditions so far this summer of above average temperatures and dry conditions contribute to the likelihood of WNV being carried in mosquitoes.
Culex mosquitoes that develop in water holding containers are the primary vectors of WNV. To prevent a yard from becoming a source for Culex mosquitoes, homeowners should make a thorough inspection of their property and remove, empty, cover or treat any water-holding containers. During the summer, mosquito larvae can complete their development in water within a week. Containers where mosquitoes commonly lay eggs include neglected swimming pools, water in loose fitting pool covers or tarps, unscreened rain barrels, rimless tires, and plastic toys.
- Drain standing water. Tires should be disposed of properly or stored inside. Rubbish barrels, wheelbarrows and small boats should be covered or stored upside down. Infrequently used pools should be covered properly or properly maintained. Tarps holding water should be emptied. Empty any unused flower pots, buckets, plastic toys and wheelbarrows. Check that gardeners’ rain barrels are covered with mesh, emptied once a week or treated with products containing Bti. Change water in birdbaths and wading pools frequently.
- Take preventative actions to avoid mosquito bites. Repair screens, wear long sleeves, pants and socks; and try to avoid outdoors during peak mosquito feeding times (usually from dusk to dawn) or if you notice a lot of mosquito activity, use mosquito netting on baby carriages or playpens. If you use a repellent you should ensure that you choose a repellent safely. Information about mosquito repellents the EMMCP and WNV can be viewed online at:
