When it gets cold outside, a fire in the fireplace creates a cozy atmosphere and pleasant warmth. However, those who gather firewood from the garden should be cautious: Some bats seek shelter for their hibernation in woodpiles. From the outside, these animals are often not visible, so a seemingly empty log can quickly become a dangerous hiding place. Moving or even burning such pieces of wood can have serious consequences for the protected animals.

Hibernation in the Woodpile
Homeowners who store firewood in the garden should be particularly vigilant right now. According to Nabu Hamburg, bats often look for protected crevices and cavities to hibernate—and they frequently find these inside a woodpile.
Smaller species, such as the Nathusius’ pipistrelle, are especially easy to overlook. Their brown fur and small size make them nearly invisible among the logs. Additionally, due to their winter torpor, they cannot alert anyone to their presence or quickly escape.

Danger from the Fireplace
The inconspicuous hiding place poses significant risks for the animals. If a log with a hibernating bat is placed in the fire, it can be fatal. Even if the bats fall to the ground when the wood is pulled out, they often appear lifeless at first glance—but in most cases, they are merely in winter torpor and not dead.

How Animal Lovers Can Help
To prevent such tragedies, experts advise special caution. It’s important to look carefully and from all sides when taking wood from the pile to avoid any accidents. If you discover a hibernating bat, do not disturb it under any circumstances.
Checking the fireplace itself can also be useful: Some animals get lost in their search for a warm refuge and end up in the chimney. The BUND Bat Center in Hanover recommends regularly inspecting not only the firewood but also the empty fireplace.
How to Act in an Emergency
If a disturbance or injury occurs, expert help should be sought quickly. Regional bat stations or centers can provide assistance. The Nabu Bat Phone at 030 284984 5000 can also help assess the situation or refer you to the appropriate place.
Until help arrives, a bat can be placed in an emergency box—a closed, empty box with air holes. According to Nabu Hamburg, “Always wear gloves when picking up a bat,” explains Ilka Bodmann. “You can place the box with the animal in a dark corner where it is quiet and undisturbed.”
