Why autumn attracts rodents

When temperatures drop, mice, rats and other rodents begin searching for warm shelter.
Basements, storage rooms, garages or suspended ceilings offer them ideal conditions: warmth, protection and access to food.

Often you don't notice them until it's already too late - typical signs are gnaw marks, droppings or noises in the walls and ceilings .


Where mice and rats hide

Rodents are true climbing artists and use even the smallest openings.
The most common entry points include:

  • Leaky doors or windows
  • Ventilation shafts and cable penetrations
  • Cellar shafts and garages
  • Cable passages and gaps in masonry or baseboards

A mouse hole doesn't have to be big – an opening of just 6-8 millimeters is enough for them to fit through.


Why an infestation should be taken seriously

A rodent infestation is not only unpleasant, but can also pose health and hygiene risks .
Mice and rats transmit pathogens, contaminate food, and can chew on electrical wires—posing a fire hazard.

In the catering and commercial sectors, the following applies: Just one inspection obliges you to take action to comply with legal hygiene regulations (HACCP).


How to prevent infestation in autumn

  1. Sealing buildings:
    Seal cracks, joints, and openings in walls, doors, and pipes. Regularly check any external transitions.
  2. Cleanliness in the storage area:
    Store food in sealed containers and clean regularly – crumbs and residues are a feast for mice.
  3. Waste disposal:
    Store waste in tightly sealed containers and dispose of it regularly.
  4. Clean up the warehouse:
    Old cardboard boxes, textiles or insulation material are popular nesting places – so check them regularly.
  5. Early detection through monitoring:
    Use bait stations or snap traps for monitoring to detect early signs of activity.
