Squirrels are some of the most familiar wildlife in suburban neighborhoods, parks, and forests. Whether you’re watching them dart across power lines or scurry up trees, you may wonder, do squirrels come out at night? If you’ve ever heard scratching sounds in your attic or seen small silhouettes moving in the dark, you may be especially curious about their nighttime habits.
In this article, we’ll explore whether squirrels are nocturnal, what times they’re most active, and what exceptions exist. You’ll also learn how their behavior compares to other animals and how to recognize whether a squirrel—or something else—is visiting your property after dark.
Squirrels and Their Daily Routine
To answer the question do squirrels come out at night, it’s important to understand the biological classification of squirrel activity. Most squirrels are diurnal, meaning they are active during the day and sleep at night. This includes:
-
Eastern Gray Squirrels
-
Fox Squirrels
-
Red Squirrels
-
Ground Squirrels
These species are most active during the early morning and late afternoon, a behavior pattern that helps them avoid the midday heat and predators.
At night, these squirrels retreat to their dens or nests, also called dreys, which they build in trees, hollow logs, or sometimes even attics in urban environments. They rest during the night and begin their routines again with daylight.
Are Any Squirrels Nocturnal?
So, do squirrels come out at night in any circumstance? The short answer is: some do, but most don’t.
The key exception is the flying squirrel. Unlike their day-dwelling cousins, flying squirrels are nocturnal and are active during nighttime hours. These unique creatures use a flap of skin between their limbs to glide through the air from tree to tree.
Flying squirrels are less likely to be seen during the day and are often unnoticed by casual observers due to their nighttime habits and quiet nature. If you notice rustling or movement at night and live near wooded areas, flying squirrels could be the source.
Key Takeaway:
-
Most squirrels are diurnal and rest at night.
-
Flying squirrels are nocturnal and are the only type commonly active after dark.
Why Might You See Squirrels at Night?
Even though most squirrels aren’t nocturnal, there are rare cases when you might spot a typical squirrel at night. If you’re asking, do squirrels come out at night, and you’ve seen one, here are a few possible reasons:
1. Disturbance or Threat
If a squirrel’s nest has been disturbed—by predators, humans, or loud noise—it may flee at night for safety. This would be an unusual event but not impossible.
2. Artificial Light
Urban environments create artificial lighting that can confuse natural sleep patterns. This may cause some animals, including squirrels, to be more active outside their normal hours.
3. Illness or Rabies
While rare, a squirrel that is disoriented or sick may exhibit unusual behavior, including nighttime activity. Always exercise caution and avoid approaching wild animals acting strangely.
Common Animals Mistaken for Squirrels at Night
If you’re still wondering do squirrels come out at night because you’ve heard noise in your attic or seen shadows moving after sunset, it’s also worth considering other animals that are more commonly active at night.
Here are a few animals often mistaken for squirrels:
-
Rats or mice – Small, quick, and noisy.
-
Raccoons – Larger and nocturnal, they make heavy footsteps and loud rummaging sounds.
-
Opossums – Slow but active at night.
-
Bats – Often seen flying near light sources or attics.
Flying squirrels, being nocturnal, could also be the cause, but without visual confirmation, it’s easy to mistake one nocturnal animal for another.
Where Do Squirrels Sleep at Night?
Most squirrels sleep in nests or tree hollows. These dens are built from leaves, twigs, and other debris. In colder regions, they seek shelter in more insulated areas, such as:
-
Tree cavities
-
Underground burrows (for ground squirrels)
-
Attics, chimneys, or crawl spaces (urban squirrels)
Once night falls, squirrels typically become inactive and enter a state of rest similar to sleep, conserving energy and avoiding predators like owls, foxes, or domestic cats.
Signs of Squirrel Activity (Day vs. Night)
If you’re trying to determine whether a squirrel is causing disturbances on your property, it helps to know when and how they behave:
Daytime Signs:
-
Scratching noises in early morning
-
Chewed tree bark or garden plants
-
Droppings near bird feeders
-
Nests in trees or attics
Nighttime Signs:
-
If you hear noises after dark, it’s likely not a standard tree squirrel.
-
Flying squirrels or another nocturnal animal could be responsible.
So, do squirrels come out at night and make noises? Only in special cases or if you’re dealing with flying squirrels.
How to Prevent Squirrels from Entering Your Home
Even if most squirrels are not active at night, you may still want to prevent all types of squirrels from nesting in your attic or home. Here are a few tips:
-
Seal Entry Points: Check for gaps in eaves, vents, or roofs and seal them securely.
-
Trim Trees: Keep branches trimmed away from the house to prevent easy access.
-
Use Repellents: Natural repellents like peppermint oil or commercial sprays can deter squirrels.
-
Install Deterrents: Motion-activated lights or ultrasonic sound devices may scare off flying squirrels.
FAQs about Squirrel Night Behavior
1. Do squirrels come out at night normally?

2. What does it mean if I hear scratching in my attic at night?
It could be a sign of flying squirrels, rats, raccoons, or other nocturnal animals. Most regular squirrels would not be active at night.

Conclusion
To answer the question do squirrels come out at night: Not usually. Most squirrel species, such as gray and red squirrels, are active during the day and sleep at night. However, the exception is flying squirrels, which are nocturnal and can be active after dark. If you’re noticing movement or noise during nighttime hours, it could be flying squirrels or a different nocturnal animal altogether.
