You’ve probably watched squirrels dart across your yard and wondered: where do they vanish to after sunset? Most tree squirrels curl up in leaf nests called dreys or squeeze into hollow tree cavities. Ground squirrels, on the other hand, burrow underground—so you’ll usually find them tucked in nests or holes close to where they spend their days foraging.
Let’s talk about how different squirrels pick their sleeping spots. Some choose high branches, others dig in the dirt, and the seasons can totally change their habits.
You might spot signs of nests, catch on to their nighttime routines, and start to appreciate just how clever squirrels are at keeping safe and warm.
Where Does Squirrel Sleep at Night?
Squirrels pick sleep spots that fit their species and what keeps them safest. Some rest high up in nests or tree hollows, while others burrow down below.
Squirrels’ Nighttime Habits and Sleep Patterns
Most tree squirrels sleep through the night. They get up early, stay busy at dawn and dusk, and nap a lot during the day.
Flying squirrels break the mold. They head out at night to forage and play, so you might actually hear them or catch a glimpse of their gliding shapes after dark.
Squirrels snuggle into nests for warmth. They might wake up now and then to move or check their food stash, but they don’t really get that long, deep sleep we humans do.
You’ll see their habits change with the seasons. Females use nests more in spring when raising babies, and everyone adds extra insulation in winter.
Tree Squirrels: Dreys and Tree Cavities
You’ll spot dreys—those round leafy nests—high up in tree branches all over neighborhoods. Squirrels build them from twigs, leaves, moss, and even feathers.
They fit them in forked branches or right against the trunk, usually with a small entrance hole turned away from the wind and rain.
Some squirrels prefer tree cavities instead. Cavities offer better shelter from storms and predators.
Squirrels often switch between a drey and a cavity, depending on weather, safety, or if they’re raising young. Both let them sleep above ground, out of reach from most ground predators.
Ground Squirrels and Underground Burrows
Ground squirrels dig burrows underground to stay safe from cold and predators. Their burrows have different chambers—one for sleeping, one for food, and another for waste.
Tunnels can stretch several feet and usually have more than one entrance for a speedy escape.
You’ll notice ground squirrels spend plenty of time inside their burrows. Some hibernate or go into torpor in winter, staying below ground for weeks.
Others just pop out for quick foraging trips during the day, then head back to sleep underground.
Dreys and tree cavities work for squirrels that live in trees. Ground burrows are perfect for squirrels that stick to the ground. Flying squirrels? They’re out and about at night, making more trips from their nests.

Unique Sleeping Spots & Seasonal Adaptations
Squirrels switch up their sleeping spots to stay warm, dry, and out of trouble. They’ll use thicker winter nests, tree cavities, or even share space with other squirrels to save heat.
Winter Nests and Communal Huddling
In winter, lots of squirrels build beefed-up, insulated nests called winter dreys. Eastern gray squirrels and red squirrels stuff in extra leaves, moss, and shredded bark to trap warmth.
If there’s a good cavity nest available, squirrels usually pick that. Hollow trees hold heat better than leaf nests, so who can blame them?
Gray squirrels sometimes pile in together. Several adults will squeeze into one den to share body warmth during the coldest spells. This helps everyone save energy.
Ground squirrels and prairie dogs do it differently: they hibernate or stay deep in their burrows instead of building big nests in trees.
Where Do Squirrels Sleep When It Rains?
When it rains, tree cavities give the best shelter. A squirrel will always pick a tree hole or a solid cavity nest first to keep the rain and wind out.
If there’s no cavity, squirrels rely on their dreys, building them with overlapping leaves and twigs that help shed water.
You might see squirrels move between nests when it’s wet. They usually keep a few dreys scattered around, so they can swap if one gets soaked.
In towns, squirrels sometimes sneak into attics or use nesting boxes people put up—though that can spark a bit of a turf war with homeowners.
Where Do Baby Squirrels Sleep?
Baby tree squirrels, or kits, sleep in really well-protected spots. The mother squirrel usually tucks them away in cavity nests whenever she can find one.
Hollow trunks do a great job keeping kits dry and out of sight from hungry predators. When she can’t find a cavity, she’ll build a deep, cozy drey instead.
She lines the drey with moss and fur, just to make sure the babies stay warm enough. Kits always huddle up with their siblings and mom for extra warmth.
You almost never spot baby squirrels alone. They stick around in the nest until their fur comes in and their eyes finally open.
If you come across a nest that looks abandoned and there are babies inside, it’s best to check with a wildlife rehabilitator before doing anything.
