Dengue Season Checklist: The Aedes Mosquito Bites in Daylight
7 min read
Short answer
Dengue is spread by Aedes mosquitoes, which bite during the day — mainly early morning and late afternoon — so night-time measures alone are not enough. The checklist: empty every water container weekly, cover storage, wear covering clothes in daylight, screen windows, and clear indoor mosquitoes as you see them.
Key takeaways
- Aedes bites in daylight — protection must cover the day, not just night.
- It breeds in clean, still water: coolers, trays, buckets, tyres, pots.
- A weekly dry-day audit of every container is the core habit.
- Covering clothes and screens beat any single device.
- Sudden high fever with severe body ache in dengue season needs a doctor, not a search engine.
Most Indian households run their mosquito defence at night. Dengue's carrier didn't get the memo — the Aedes mosquito bites in daylight, which is why a family that sleeps under nets can still end up in a hospital queue in October.
The daytime problem
Aedes aegypti is most active in the early morning and in the few hours before dusk. It is a low flyer that bites ankles and feet, rests indoors behind curtains and under furniture, and rarely announces itself with the whine people associate with mosquitoes. Night-only measures miss it entirely.
The weekly audit (the part that actually works)
Aedes breeds in clean, still water close to where people live — not drains. Once a week, walk the house with the audit in mind:
- Desert coolers: drain fully, scrub, refill — don't just top up
- AC drip trays and fridge trays: empty and wipe
- Plant saucers, vases, money-plant bottles: change the water
- Buckets, drums and storage tanks: keep tightly covered
- Balcony, terrace and parking: remove tyres, broken pots, sunken tiles that pool water
- Roof gutters and the society's terrace: report standing water
A container that holds water for about a week is enough for a full mosquito life cycle. Weekly is not an arbitrary interval.
Daytime protection for people
- Full-length clothing for kids during morning and evening play — ankles and feet first
- Screens on windows and doors, especially in rooms used during the day
- Sweep indoor resting spots — behind curtains, under tables and beds, dark corners — with a handheld zapper
- Repellent on exposed skin where appropriate, checking age guidance for young children
When to stop reading and call a doctor
Sudden high fever with severe headache, pain behind the eyes, joint and muscle pain, nausea or a rash during dengue season deserves medical attention, not a search engine. Warning signs like severe abdominal pain, persistent vomiting, bleeding gums or extreme lethargy are urgent. This article is prevention advice, not medical advice.
Living in a flat?
Most of the breeding sites that matter are shared: terraces, sumps, tanks, basement water. The city-by-city breakdown is in the apartment guide, and it's worth taking to the society group before dengue season peaks.
And how long does the season run? When mosquito season actually ends depends on your city — in Delhi the October–November peak only breaks around mid-December.
Daytime cover, chemical-free.

When do dengue mosquitoes bite?
Aedes mosquitoes bite mainly in daylight — early morning and the few hours before dusk — which is why bed nets alone do not prevent dengue.
Where do dengue mosquitoes breed?
In clean, still water close to homes: coolers, water storage drums, buckets, plant saucers, AC drip trays, discarded tyres and roof puddles.
How can I prevent dengue at home?
Do a weekly audit that empties every standing-water container, keep storage covered, screen windows, wear covering clothes during the day, and clear indoor mosquitoes as you see them.
