Why the alert came early this year
Municipal health departments across several North-Indian cities have begun issuing pre-monsoon mosquito advisories in February — a sharp shift from the usual April–May window. The trigger is a warmer-than-normal late winter combined with sporadic rainfall, which together extend the Aedes aegypti breeding season.
Aedes aegypti is the primary vector for dengue and chikungunya. Unlike Anopheles (the malaria carrier), it bites by day and prefers clean, stagnant water inside our homes — a few millilitres in a flower-pot saucer is enough.
What every household should do this fortnight
- Walk through your balcony and roof once a week — empty every plant saucer, paint tin and unused bucket.
- Clean the overhead water tank and ensure the lid actually seals.
- Throw away tyres, broken pots and any other water-holding junk lying behind the house.
- Inspect AC drip-pan drains and bathroom floor traps — both are classic indoor breeding sites.
For RWAs and apartment societies
Common-area mosquito control is more effective when it combines fogging (which only kills adults) with larviciding of stagnant pools and a documented inspection log of basements, parking lots and rooftop water tanks. A monthly mosquito audit is now considered baseline hygiene in well-managed societies.
Public-health reminder: only female mosquitoes bite, and only the ones that have already fed before lay eggs. Eliminating breeding water removes the next generation entirely — it is far more effective than chasing adults with sprays.
