Mosquitoes spend most of the day resting in cool, shaded, humid areas. That includes under leaves, inside shrubs, beneath decks, and along fence lines where they're protected from sun and wind.
If mosquitoes only seem to show up at dusk, it can feel like they come out of nowhere. But they’ve been on your property all day. They were just hiding.
Not that this makes it any better. In fact, it’s more unsettling that way. But the good news is that mosquitoes are surprisingly fragile.
Case in point, mosquitoes don’t like direct sunlight. That and low humidity can dehydrate them and kill them in a matter of hours. So during the day, they tuck themselves into the most sheltered spots they can find. Anywhere shady and humid.
This is why a yard can feel mosquito-free at noon and be unbearable by 7 PM. The mosquitoes didn’t fly in from somewhere else. They were resting ten feet from your favorite patio chair the whole time, waiting for temperatures to drop and humidity to rise before they resumed feeding.
Spraying a yard while mosquitoes are flying means trying to hit a moving target. Treating vegetation and shaded resting sites where they spend most of their day puts the products exactly where they’re likely to run into them.
It also explains why certain yards have worse mosquito problems than others. Properties with dense landscaping, heavy tree canopy, ground cover, and lots of shaded structure tend to hold more resting mosquitoes than open, sunny lots. You don't need standing water on your property to have a mosquito problem. All you need is a good daytime habitat.
