Mosquito Control at Home & Society — What Actually Works

Three mosquito species matter most in Indian cities. Aedes aegypti, the yellow-and-black-striped daytime biter, carries dengue and chikungunya, and breeds in clean water. Anopheles, active at night, carries malaria and breeds in slow-moving natural water. Culex, the common house mosquito, carries filariasis and Japanese encephalitis, and breeds in dirty stagnant water.

All three lay eggs on the surface of standing water. Eggs hatch into larvae within 24–48 hours, larvae develop into adults in 5–10 days. This is why a single week of standing water in a container is enough to produce a swarm.

The society-level fight is fundamentally different, because breeding sites are shared: the overhead tank room, the STP, the swimming pool area, blocked chajja gutters, and — critically — the shared water storage that most residents don't inspect.

The standard protocol for societies during monsoon is: monthly professional fogging of common areas at dusk, monthly larvicide treatment of drains and any standing-water spots, weekly walk-throughs by the maintenance team to empty containers, and mesh screens on the STP vents. Municipal fogging trucks visit occasionally but are not a substitute — they treat the road, not your compound.

Offices need the same monthly fogging + larvicide protocol as societies, plus attention to the pantry (open water dispensers), the terrace (water tank access), and the parking basement (drain sumps). Employee attendance drops sharply during dengue season, and a well-run pest programme is a straightforward investment.

Fogging (thermal or ULV) releases a fine mist of insecticide into the air that kills adult mosquitoes on contact. It gives you 24–48 hours of visible relief but does not treat larvae in standing water — so within 3–5 days, new adults emerge.

Larvicide treatment applies a specific chemical (typically temephos or a biological like Bti) to standing water and drains, killing larvae before they mature. A properly-applied larvicide treatment lasts 30 days. The professional combination is fogging (immediate relief) plus larvicide (30-day residual) plus weekly water audits (prevention).

For an individual home, a professional treatment is worth it when: you have a garden or a large balcony, you live on a ground floor near stagnant water, someone in the family is at elevated risk (child, elderly, pregnant), or you're already seeing mosquitoes despite standard precautions.

For a society or office, monthly professional treatment during monsoon is the norm.

Mosquitoes breed in standing water — sometimes as little as a bottle-cap's worth. Individual homes control mosquitoes through weekly water audits, mesh screens, and vaporisers. Societies and offices need monthly professional fogging plus larvicide during monsoon. Municipal fogging alone is not sufficient. Dengue prevention is a personal-responsibility problem more than a treatment problem.
