Yes, mosquitoes can be worse near the beach. Salt marsh mosquitoes breed in brackish water, bite aggressively during the day, and can travel 5-10 miles.
If you thought the ocean breezes were going to keep mosquitoes away, you’d likely be disappointed. Salt marsh mosquitoes have evolved to thrive in exactly the environment that beaches provide.
You might find this frustrating. And that’s a reasonable response, given that this particular subset of mosquitoes can breed just fine in tidal pools, marshes, and coastal ditches just behind the immediate shoreline. These are not exactly puddles that go away after the sun shines for a while. Coastal areas have extensive salt marsh habitats that can produce millions of mosquitoes in the summer.
Unlike typical backyard mosquitoes that are most active at dawn and dusk, salt marsh mosquitoes bite aggressively throughout the day, even in direct sunlight. You can’t avoid them just by timing your beach activities. Whenever you’re outside, they’re going to be active.
As if that weren’t enough, salt marsh mosquitoes are also better at flying. Regular mosquitoes might travel a few hundred yards from their breeding site, but salt marsh mosquitoes can fly 5 to 10 miles—sometimes even 40 miles when the wind is just right—searching for blood meals. This means that even if your property doesn't have standing water, you're likely to receive waves of migration from nearby marshes.
Tidal patterns can also make mosquitoes worse. During moon tides, dormant eggs that have been waiting on the marsh surface can suddenly hatch all at once when high tides flood the marsh. And it’s then that mosquito activity can become nearly unbearable without protection.
Wind provides some relief since mosquitoes struggle to fly in strong breezes. But as soon as you move to your deck, patio, or any area with windbreaks, mosquitoes will find you.
The solution isn’t to avoid the coast. That’s neither possible nor desirable. Rather, it helps to make your property a protected zone. You can’t control the salt marshes where mosquitoes breed, but you can create a barrier on your property that eliminates the ones who make the bad decision to rest on your property.
