Ever spot a squirrel darting through the branches during the day and wonder where it disappears after sunset? Most tree squirrels curl up in leafy nests called dreys or tuck themselves into hollow tree cavities. Ground squirrels dig down and spend the night in burrows beneath the earth. These cozy shelters keep them out of reach of predators and shielded from rough weather.

If you look closer, you’ll notice squirrels change their routines with the seasons. They use their nests and burrows not just for sleeping, but for stashing snacks, staying warm, and raising their babies.
Some of those hideouts? Honestly, they look pretty inviting.
Where Do Squirrels Go at Night?
You’ll find out where different squirrels sleep and why they choose those particular spots.
Let’s break down how tree squirrels, ground squirrels, and flying squirrels spend their nights.
How Tree Squirrels Spend the Night
Tree squirrels—think red and gray squirrels—usually build dreys from twigs and leaves high up in branches. These nests sit about 6 to 15 feet above the ground and get lined with moss or grass for extra warmth.
Sometimes, they move into hollow tree cavities if they find one that fits. Cavities offer stronger shelter from wind and rain.
If you notice a mess of shredded bark or a pile of twigs in a tree, that’s probably a drey. In cities, squirrels sometimes sneak into attics or eaves when trees are lacking.
When the temperature drops at night, they huddle together in their nests or cavities to keep warm.
Ground Squirrels’ Nighttime Retreats
Ground squirrels don’t sleep in trees—they dig burrows underground with tunnels and little chambers. Some burrows are short, but others stretch for several feet and have grassy nests inside.
Fresh dirt or a cluster of holes near a mound usually means a burrow is active. These homes protect ground squirrels from hungry owls, sneaky foxes, and wild swings in temperature.
During winter, some ground squirrels go into a deep rest that’s a lot like hibernation. They’ll stay tucked in their burrows for days or even weeks.
If you’re looking for their nests, watch for small dirt mounds and well-worn trails.
Flying Squirrels and True Nocturnal Activity
Flying squirrels are the night owls of the squirrel world. After dusk, they glide from tree to tree using skin flaps called patagia.
You almost never see them during the day. At night, they search for insects, nuts, and fungi, then rest in tree cavities, old woodpecker holes, or nest boxes.
Because they move in the dark, flying squirrels dodge many daytime predators. Still, they have to watch out for owls and raccoons at night.
Want a chance to spot one? Try setting up a motion camera at dusk near a tree cavity, or hang a nest box 12 to 20 feet high. Maybe you’ll catch a glimpse of their gliding shadow.
What Do Squirrels Do While Sheltering?
Squirrels use their hidden, insulated spots to sleep, groom, stash food, and stay out of trouble. They rest, but they’ll also check their surroundings and look after their young if they have any.
Nighttime Squirrel Behavior
Most tree squirrels stay active during the day and head back to their dreys or tree cavities at night. They usually settle in before dusk and keep pretty quiet until sunrise.
If they hear something suspicious, they wake up, peek outside, or shift around to get comfortable.
Flying squirrels break the mold—they leave their nests after dark to glide and search for food. Ground squirrels, on the other hand, stay put in their burrows and rarely venture out at night.
In cities, artificial light sometimes makes squirrels a bit more active after sunset, but not by much.
Sleep Patterns and Baby Squirrels
Adult squirrels don’t sleep all night in one stretch. Instead, they take a few short naps with alert moments in between.
They curl up with tails wrapped tight to keep warm, and they’re quick to wake if startled.
Baby squirrels need plenty of deep sleep to grow. Their mothers keep them warm and might nurse them a few times overnight.
If you ever find a quiet leaf nest, you might catch some faint sounds from the pups. The mother returns often to feed and groom them.
Staying Safe from Predators
Squirrels pick sleeping spots that are hard for predators to reach and tough to spot. Most tree squirrels build dreys high in the forks or use tree cavities with narrow entrances to keep out cats, foxes, and owls.
They stay alert, too—a squirrel might freeze, flatten against a branch, or dash off if it senses danger.
Ground squirrels warn each other with alarm calls. If you look closely, you’ll see chewed nest entrances or multiple exits in their burrows. They definitely plan their escape routes.
Adaptations in Urban Environments
Urban squirrels definitely change where they shelter and how they act at night. You might spot them tucked away in attics, chimneys, or wedged behind siding because those places stay warmer and drier.
They still build leaf nests up in trees, but they’ll often grab insulation or bits of fabric if they find any. It’s not unusual to see scraps of old clothing poking out of a squirrel nest in the city.
Streetlights and backyard lights mess with their usual schedules. Some squirrels make quick nighttime runs to bird feeders or rummage through trash cans, even though most of them still try to avoid the dark.
Their ability to adapt keeps them going, but it also leads to plenty of run-ins with people. If you’re curious about where squirrels sleep and how they choose their nests, check out this article: Where Do Squirrels Go at Night?.
