Ultra-low-volume passes lower biting pressure briefly; embryos still mature in spoons of water after rain bands pass—larval habitat removal must repeat weekly through monsoon.

Six repeatable habitat steps

• Empty coolers, trays, tarp folds weekly.
• Seal stored water drums with gasket lids.
• Clean gutters stopping silent ponding above ledges.
• Change plant saucer and vase water every few days.
• Remove tyres, tins, shells where monsoon washes pool.
• Use biological or approved larvicides in sumps ponds must retain.

Yard vignettes tied to Kerala reality

Shared podium sumps and lift pits need society coordination; balconies still refill AC condensate trays and planter saucers overnight—audit gutters, lidded drums, tyre stacks, and choked downspouts weekly.

Reminder line: negligible water volume suffices for emergence—weekly discipline beats heroic annual fog budgets.
