A proposal to reduce mosquito breeding sites

I sent this to NEA not too long ago. Just an idea...

Dear Sir/Madam,

While it is a good idea to "cover bamboo pole holders when not in use", I would like to propose a possible solution to prevent water from accumulating in bamboo pole holders.

During house-to-house inspection in mosquito breeding zones, perhaps NEA can request residents to allow EHOs to drill holes at the neck of pole holders to prevent water from accumulating.

I hope this might prove feasible and do more to reduce mosquito breeding sites.
