Mosquito season starts when two things meet: standing water and mild weather. That is why mosquitoes increase one to two weeks after rain, and in autumn and spring when temperatures are moderate. They drop in peak heat and in severe cold, but do not vanish completely if standing water is nearby.
When do mosquitoes increase?
- After rain: water collects, and larvae become adults within 7 to 14 days.
- In mild weather: temperatures between 20 and 30°C suit breeding best.
- With high humidity: especially in coastal cities.
- At dusk and dawn: the main biting times.
When do mosquitoes go away?
| Weather | What happens |
|---|---|
| Very hot and dry | Fewer, as water evaporates and adults live less |
| Very cold | Breeding stops; some species shelter until it warms |
| Mild and humid | More, breeding fast |
| After rain | A large wave within one to two weeks |
Why do I have mosquitoes all year?
Because there is standing water near you:
- Plant pot saucers and AC drain water.
- Uncovered tanks and barrels.
- Floor drains and manholes with standing water.
- Neglected pools or fountains.
- Septic tanks or sewage leaks.

Mosquito season FAQs
How long do mosquitoes live?
A female usually lives two weeks to a month; males live less.
Do mosquitoes die in winter?
Not all. Some shelter in warm places, and eggs survive until conditions return.
Why do mosquitoes increase after rain?
Rain leaves pools of water where females lay eggs, and a new generation emerges within days.
