URGENT / IMPORTANT

Dear QPS Chua Hock Beng & RE Neary Clevan Medolin

In view of the recent cases of mosquito larvae findings at LTA sites, and going into mosquito breeding season, please inform your RTOs for our respective areas to check thoroughly for any mosquito breeding on site.

To step up checks on contractors to ensure prevention measures are taken e.g. using abate, check for cracked barriers, etc. (to post photos in our respective WhatsApp Groups on the findings)

Please see attached photos with details of the recent findings below for sharing with your RTOs

Details	Photos
Larvae found in pit under column base plate
Larvae found in cut post of directional sign
Larvae found in IBC Tank
Larvae found in empty WFB due to water seepage from minor crack at the side of WFB
Water stagnation in turfing area (potential mosquito breeding)

Thank you.
