Noise nuisance from animals in the attic can turn into a nightmare. It gets loudest in the evenings and at night, and sleep is sometimes almost impossible to think of. In order to be able to take effective action against troublemakers, it is important to identify who is looking for shelter in your roof.

  • Rats
  • Dormouse
  • Pigeons


Martens are particularly loud. They turn night into day. Sleep is hard to think of when a marten has lost its way into your attic. Martens can only be found in the attic or on the sloping ceilings, the false ceiling or the partition walls remain quiet. Marten often leave fur behind.

Other signs of a marten in the roof are thumb-sized excrement on the floor and the large amounts of urine the animals leave behind. Marten excretions smell very strong, in the worst case they seep into and through the ceilings. Martens especially like to gnaw on cables and electrical installations, and pipes are not safe from the sharp teeth either.

If a live trap is not accepted by the animal with the appropriate attractants, you only have to go to the professional exterminator - due to the high risk that these animals pose, you should definitely take action and try to get rid of the uninvited guest as soon as possible. However, you are not allowed to kill the animal - martens are protected.

To avoid a renewed infestation with martens, you can attach marten brushes in the rain gutters and on the downpipe. The hard, upward-pointing bristles ensure that martens, raccoons and other animals do not walk over them because of their sensitive paws.


The nimble, skillful rodents find their way into the building through even the smallest crevices. Squirrels are diurnal, so it often takes a long time for homeowners to realize that squirrels have taken shelter in their home. Their potential for destruction is relatively low - so you don't necessarily have to move heaven and earth to drive the animals away.


Only 2 of the 25 bat species in Germany seek protection in human dwellings. The nocturnal animals only make noises before they fly off to hunt at night, otherwise the winged roommates are quite calm. You can use your leftovers as fertilizer for the garden. Bats are under nature protection, as a rule you have to come to terms with the useful animals.

If you feel severely disturbed, you should consult the local conservation association and ask a bat expert for advice. Relocating bats is usually not possible. In autumn the animals will leave your attic anyway, next year you can seal the building envelope to prevent re-colonization.

Mice and rats

The nocturnal animals cause great damage in residential buildings. They are not only in the roof but also in false ceilings and walls. The rodents' excrement leave a strong, pungent odor. To an even greater extent than mice, rats can transmit diseases to humans. You should take steps as soon as possible to get rid of the uninvited guests.

In most cases, however, only going to the exterminator helps in the event of an infestation with mice or rats. In order to avoid resettlement, you often have to undertake major renovation and refurbishment measures in order to seal the building envelope accordingly. But even that is no guarantee that you can permanently exclude the intelligent pests.


Today raccoons are widespread in Germany. Raccoons are very persistent, they even jiggle loose tiles to gain access to a roof. Once moved in, it is very difficult to get rid of a raccoon. The animals are extremely loud and cause great damage to electrical installations, but also to the building itself. They tear up and destroy insulation, the strong-smelling excrement quickly penetrate ceilings and beams.

A raccoon's bite is very painful, and the animals are often carriers of rabies. Contact an exterminator - they will catch the animal with a live trap and release it back into the wild a long way away from your home.


Dormice are also nocturnal and usually travel in large groups. They leave visible damage to cables, insulation and insulation. Like martens, dormice are under nature protection, so you can only use live traps against the animals. Dormice are quite harmless to humans, but a professional can help with a stubborn infestation.


Pigeons are not only very loud, they also cause great damage to the structure of the building. The aggressive faeces of the animals not only attack the building materials, it also contains pathogens that remain active for up to a year and cause pneumonia or meningitis in humans.

Pigeons are extremely difficult to drive away, you should consult an expert in pigeon control who can install the appropriate defense systems.

In order to keep pests away in the long term, after the animals have been successfully driven out of the roof, you definitely have to take sealing measures on the building envelope - otherwise the stubborn roommates are always looking for ways back to the warm, comfortable quarters in the human dwelling.
