Female mosquitos need blood meals to produce eggs, and a place to lay those eggs which is safe from predation. Both steps can be somewhat controlled by preventing bites onto humans, and by removing standing water, but you will never prevent mosquitos from biting wild mammals or pets, nor will you ever get all of the standing water sources (one old tire could spawn thousands of mosquitos). One of the biggest limits is weather and climate. Mosquitos don't exist here in New England for half the year, but if we increase the temperature by 2 C, we'll probably be facing them for 7-8 months and they'll rebound harder and faster.
