Why Mosquitoes Increase After 6 PM in Hyderabad (Expert Guide 2025)
Every evening, like clockwork… Around 6 PM, mosquitoes suddenly appear everywhere. More in balconies, More in parks, More in bedrooms, More in open areas, More near drainage, More around lights.
It’s not your imagination. And it’s not random. There are scientific, weather-based, and Hyderabad-specific reasons why mosquito activity shoots up after 6 PM.
Let’s break it down clearly, simply, and practically — Neil Patel style.
1. Hyderabad’s Temperature Drops After Sunset (Perfect for Mosquito Flight)
Mosquitoes cannot fly well in: Harsh sunlight, High heat, Strong winds. In Hyderabad, daytime temperatures are usually: Too hot, Too dry, Too bright.
But after 6 PM: Heat reduces, Air becomes cooler, Wind becomes calmer. This creates the ideal conditions for mosquitoes to fly and attack.
2. Humidity Rises Sharply After Evening in Hyderabad
Hyderabad’s climate becomes more humid after sunset due to: Water evaporation, Plants releasing moisture, Drainage lines cooling down, Evening temperature drop.
Mosquitoes LOVE humidity. It keeps their wings moist and helps them fly faster. High humidity = High mosquito activity.
3. Mosquitoes Are Naturally Evening & Night Feeders
Mosquitoes are crepuscular — which means they are most active at: Dawn (6 AM to 8 AM), Dusk (6 PM to 9 PM). This is their natural feeding cycle.
This is why mosquitoes bite more: During evening walks, At parks after sunset, In balconies after 6 PM, Near lights at night. Hyderabad’s climate intensifies this behavior.
4. Evening Light Attracts Mosquitoes (Especially Tube Lights & LEDs)
Mosquitoes are extremely attracted to: White tube lights, LED lights, Mobile screen light, TV light, Balcony light.
After 6 PM, when homes light up, mosquitoes are naturally drawn toward: Windows, Balconies, Open doors, Vent gaps. This is why evening is the worst time to keep windows open.
5. Peak Mosquito Activity Starts When Humans Become Active Outdoors
After 6 PM: Kids play outside, People go for walks, Gyms get busy, Shops stay open, Open plots become active. More humans → More carbon dioxide → More sweat smell → More movement → Mosquitoes instantly get attracted. They use CO₂ and body odor to track humans.
6. Mosquitoes Breed in Stagnant Water — Which Accumulates All Day
Daily activities create water stagnation: Car washing, Balcony cleaning, Plant watering, AC water dripping, Tank overflow, Drain seepage. By evening, this water: Cools down, Gets algae, Becomes mosquito-friendly. Fresh larvae hatch around sunset. This increases mosquito count suddenly.
7. Hyderabad Has Open Drains — Most Active After Sunset
Areas with: Open nalas, Dirty drainage lines, Garbage dumping, Water stagnation. Show massive mosquito activity after sunset. Mosquitoes rest inside these drains during the day. After 6 PM → they start flying out to feed.
8. Culex & Aedes Mosquito Species Peak at Evening
Hyderabad mainly has: Aedes (Dengue mosquito), Culex (Common house mosquito), Anopheles (Malaria mosquito). All three increase their activity between 6 PM to 10 PM. This is their biological feeding window.
9. Kitchens & Bathrooms Release Moisture at Night
Around evening: Bathrooms get wet from showers, Kitchens release heat + moisture, Food smell increases, Water from cooking evaporates. This moisture attracts mosquitoes entering through: Bathroom drains, Kitchen windows, Ventilators, Balcony doors.
10. Wind Speed Drops After 6 PM — Mosquitoes Prefer Still Air
Mosquitoes cannot fly in heavy wind. But after 6 PM, Hyderabad’s wind speed usually drops. Still air = Easy mosquito movement. This is why evenings feel like mosquito attack mode.

Here’s the exact fix that works:

8. Do Evening Pest Control for Maximum Impact
Evening is the BEST time for: Fogging, Spray, Larvicide. Because mosquitoes are fully active.
Final Takeaway: Mosquitoes Don’t Increase Randomly — Hyderabad’s Climate Makes Them Peak After 6 PM.
Because of: Cooling temperature, Rising humidity, Stagnant water, Shared drains, Human evening activity, Biological feeding habits.
