Yes, and most common mosquito species can fly 1 to 3 miles from where they hatched. If your property borders woods, a creek, or any area with standing water and dense vegetation, mosquitoes are almost certainly migrating into your yard.

If your yard backs up to trees and you feel like no amount of cleaning up standing water on your property makes a difference, this is probably what’s going on. Your yard is not the source of your problems, but that doesn’t mean it’s not a destination for mosquitoes coming in from elsewhere. And that's a frustrating situation to be in.

Wooded areas are a great place for mosquitoes to live. They provide shade, humidity, and standing water. Mosquitoes will then rest in the shaded vegetation during the day, breed in standing water, and become active at dusk. That’s when they start flying toward nearby yards looking for a blood meal.

The flight range depends on the species. Some common species like Aedes vexans can fly several miles from their breeding site. Others, like the Asian tiger mosquito, tend to stay closer to where they hatched, usually within a few hundred yards. But even a short-range species in the woods 100 feet from your patio will have no trouble reaching you. And that’s assuming the wind isn’t carrying them farther than they would otherwise be able to fly.

This is one reason why eliminating standing water on your own property, while helpful, doesn't always solve the problem. If the problem is your neighbor’s unkempt yard, or a nearby drainage area, you can’t control it directly.

That doesn’t mean you’re powerless, though. When mosquitoes fly in from the woods, they’ll still need shade and moisture to rest between feedings. If your property has dense shrubs, tall grass, leaf piles, and areas under decks, they can all serve as daytime refuges. If you remove or treat the areas where mosquitoes hide and rest, it will make your yard a lot less hospitable to them.
