Flats' bamboo pole holders a mosquito hazard

Older Housing Board flats have bamboo pole holders that may collect water during rain, inadvertently promoting the breeding of mosquitoes.

HDB dwellers are encouraged to use a plastic cap over these bamboo pole holders. This requires the cooperation of residents, which can be tricky.

Moreover, the plastic caps often crack after a period of time as they are exposed to the hot sun.

Could HDB consider drilling holes at the bottom of these bamboo pole holders so that they allow water to be drained naturally?
