Yes, and the main reason is because shaded yards are cooler and more humid. Mosquitoes dry out in the sun. Shaded yards give them a place to rest during the day.
You picked the lot with the big oaks and the mature maples because it’s beautiful, but the shade also makes summer bearable. Then the mosquitoes start biting and you wonder if it’s worth it.
Mosquitoes rest a lot more than they fly. They’re very vulnerable when it’s hot and dry outside, and it doesn’t take long for them to desiccate. So they try to stay out of the sun and in cooler, humid environments. If you’ve ever seen mosquitoes hiding on the undersides of leaves around noon, or anywhere else like that, that’s why.
Ground cover beneath a canopy stays damp longer after rain. Leaf litter decomposes more slowly and holds moisture. Both of these are also examples of microclimates that shaded yards provide while mosquitoes wait until conditions are right to seek out their next blood meal.
In Southern New Hampshire, where many residential lots are carved from wooded land and surrounded by mature forest, heavy shade is the norm rather than the exception. That’s why lots like these tend to have more mosquito problems. The dense understory of many lots never fully dries in the summer.
That’s not to say sunlit yards are immune to mosquitoes. They can still breed in standing water regardless of sun exposure. But crossing a sunny lawn to reach a host is a bigger ask than simply hiding in the bushes until the time is right.
The good thing is that you don’t need to cut down trees or even aggressively rip out landscaping to handle mosquitoes. You just need regular treatment to keep the population in check, which is something Mosquito Squad of Southern New Hampshire can provide. Mosquito Squad focuses treatments on the places that mosquitoes rest during the day. That helps control mosquitoes on a population level so you can enjoy the many good qualities of a shaded lot in the summer.
