how long does it take for mosquito larvae to hatch?

Answer 1

"Time for eggs to hatch varies with species from 16 to 24 hours to more than 2 years for floodwater mosquitoes. Larvae develop through 3 molts (4 instars) over a period of about one week before pupating. Adults emerge from the back of the pupa after 2 to 3 days. Adults live for 2 or more weeks, although standing water species overwinter as mated, engorged females."

Answer 2

2-3 days
