A crackling fireplace brings cozy warmth during the cold season. But those who fetch firewood from the garden should be cautious, as a bat may have nestled in the quiet stacks for hibernation. Often, the wood appears completely lifeless, even though it contains a protected wintering spot—and that’s precisely why the animals face great danger during transport or burning.
Hibernation in the Firewood Stack
Homeowners who store firewood in the garden should be particularly vigilant right now. According to Nabu Hamburg, bats like to find protected crevices and cavities for hibernation—and they often 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 draw attention to themselves 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 at all.

How Animal Lovers Can Help
To avoid such tragedies, experts advise special caution. Above all, look carefully and from all sides when taking wood from the stack to prevent 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 search of a warm shelter and end up in the chimney. The BUND Bat Center in Hanover, therefore, recommends regularly checking not only the firewood but also the empty fireplace.
Acting Correctly in an Emergency
If a disturbance or even injury occurs, expert help should be sought quickly. Regional bat stations or centers offer support. The Nabu Bat Phone at 030 284984 5000 can also help assess the situation or refer you to an appropriate place.
Until help arrives, an animal can be placed in an emergency box—an empty, closed box with air holes. According to Nabu Hamburg, “Always wear gloves to pick up a bat,” explains Ilka Bodmann. “You can place the box with the animal in a dark corner where it is quiet and undisturbed.”
