The House lives!
Bat species who live in buildings are for example Eptesicus serotinus and Pipistrellus pipistrellus. But many other bat species can live in buildings. They use for example gaps and cracks as quarters and attics are gladly accepted, too. Also Myotis myotis belong to the bat species living in buildings: they populated large attics of churches, monasteries and palaces.
The bat populations, however, are greatly diminished in the last 40 years. Causes of their extreme decline are mainly lack of food due to the use of pesticides in agriculture; poisoning by wood preservatives used in buildings and the destruction of quarters due to roof works, renovations and thermal insulations.
Typical Bat Quarter possibilities
Homeless in the freezing cold! Bats don't find Winter-quarters
With the start of cold in northern Germany many bats are looking for a frost-free place for the winter. But unfortunately due to tree fellings and house renovations there is hardly any space for bats. In Winter many bats can be seen flying around in a desperate attempt to save there lives. Sometimes they fly right into buildings or freeze to death. Please help the bats to survive. – Take action for the conservation and creation of winter quarters. – Please, spread the word! Thank you for your help.
Roof tarpaulin / Construction tarpaulin
Bats can also roost in the crevices of buildings, roof crevices and attics - this applies to both individual animals and colonies. Please make sure that the construction plans do not close off any quarters when covering for roof work / building work.

Beware of renovation work, building demolations and thermal insulation
During renovation and thermal insulation of facades and roofs, many - usually barely visible - bat quarters are lost because the entrances are closed or because the cavity disappears as a result of the measure. In the worst case, the animals are seriously injured or walled in during the work. Another problem is that the heat is kept inside the building after insulation, but outside, where the wintering bats are sitting, it is no longer sufficiently warm, so that the area is no longer suitable for hibernation in severe frost.
Attention when renovating the attic of buildings!
Bats love to stay in the attic of buildings: the animals crawl under the attic and look for suitable sites there. Even Winter quarters may be located under an attic. In the photo the bat droppings can be seen after the attic was removed. For attica renovations there are solutions to preserve the bat roosts or to provide new quarter at the same place.
Due to renovations and insulations of facades and roofs, many - usually barely visible - bat roosts got lost because the entrances to the quarters get sealed or the quarter gets totally destroyed. In the worst case, the animals are immured alive. Another problem is that after isolation the heat is kept inside the building, so the bat quarters gets too cold in Winter and the quarter is no longer suitable for bats.
How can I recognise bat quarters in buildings?
What to do when you have a bat quarter in your house?
If no changes to the house are planned, then nothing is to do. If possible, please try to minimize the threads for bats at your house.
If you are planning renovations, thermal-isolations or any other changes at the house, it is very important to pay attention to the quarter / quarters. Therefore bat experts should examine the building, even if you only suppose that there could be a bat quarter. This is the only way to avoid that the bat quarter gets destroyed or sealed.
Remodeling / renovation / demolition despite bat quarters?
Injured bat by roof renovation
With heavy, severely inflamed abrasions on the shoulder and face that contained grains of sand and wood chips, this bat came to our ward one week ago in mid-March 2018. In the wound cleaning and removal of the foreign body was also found out that under the neck and scalp an air emphysema was. Presumably, she is the victim of a roof renovation, where she sat between stones and was squeezed. Fortunately, the lung injury is probably already stuck, the emphysema is now no bigger and the breath sounds have disappeared after the antibiotic treatment also. The one photo was taken after the initial treatment, now the healing is even more advanced and she eats without end! In the first flight exercises in about 2 weeks will show whether the lung function is sufficient for longer flights.
We hope the best, so that she can go back to freedom in the summer - but she will have to look for a new winter home next winter ...
