Why autumn attracts rodents

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

Often you only notice them when it's already too late – typical signs are gnaw marks, droppings, or noises in 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 pipe penetrations
  • Basement shafts and garages
  • Cable passages and gaps in masonry or baseboards

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


Why an infestation should be taken seriously

An infestation of rodents is not only unpleasant but can also bring health and hygiene risks.
Mice and rats transmit pathogens, contaminate food, and can gnaw on electrical wiring – which poses a fire hazard.

In gastronomy and business: Even one sighting obliges action to comply with legal hygiene requirements (HACCP).


This is how you prevent an infestation in autumn

  1. Seal the building:
    Seal cracks, joints, and openings in walls, doors, and pipes. Especially check transitions to the outside regularly.
  2. Cleanliness in the storage area:
    Store food sealed 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. Tidy up storage:
    Old boxes, textiles, or insulation material are popular nesting sites – so check regularly.
  5. Early detection through monitoring:
    Use bait stations or snap traps for monitoring to detect early signs of activity.
