❑ Provide all-weather road access (with provisions for turning a full-size work vehicle) <br /> along at least one side of large aboveground structures that are less than seven meters <br /> wide or both sides if shore-to-shore distance is greater than seven meters. <br /> Note: Mosquito larvicides are applied with hand held equipment at small sites and with <br /> backpack or truck mounted high-pressure sprayers at large sites. The effective swath <br /> width of most backpack or truck-mounted larvicide sprayers is approximately 20-25 feet <br /> (6-7meters) on a windless day. <br /> ❑ Build access roads as close to the shoreline as possible to allow for maintenance <br /> and vector control crews to periodically maintain, control and remove emergent <br /> vegetation and conduct routine mosquito monitoring and abatement. Remove <br /> vegetation and/or other obstacles between the access road and the structure that might <br /> obstruct the path of larvicides to the water. <br /> ❑ Control vegetation (by removal, thinning, or mowing) periodically to prevent barriers <br /> to access. <br /> 0000 <br /> 4 <br />
