Egg-to-Adult Development Time vs Temperature
Number of days required to complete the full mosquito development cycle — from egg to adult — at different water and ambient temperatures. Higher temperatures dramatically compress the breeding timeline, accelerating population growth.
38 days
At 15°C (59°F) — slow season development
8 days
At 30°C (86°F) — peak summer speed

Faster at peak vs cool temps — population surge risk
