Methods of controlling mosquitoes in Wayland. Catch basins in town have been treated 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 Board of Health requests the public check catch basins in their neighborhoods. If your catch basin does not have a fresh white mark, please contact the Board of Health at 508-358-3617 and give us the exact location of the catch basin.
