Why rats move into heating units and boiler rooms in winter: dangers and solutions

During the winter, rats look for warm, safe places to hide from the cold, and heating units, boiler rooms, and other technical rooms are ideal for this. In such places, they not only quickly settle, but can also cause serious problems for both apartment buildings and private homes.

Why do rats choose heat nodes?

  • High temperature – heating devices ensure a warm environment even on the coldest days.

  • Low human traffic – these rooms are often rarely visited.

  • Lots of hiding places – pipelines, cables, open cavities create perfect places for nests.

  • Food sources – Garbage or leaky pipes can provide rats with water and food debris.

What danger do rats pose in these premises?

  • Wire gnawing : can cause a short circuit or even a fire.

  • Damage to water and heating systems : rats can cause leaks by gnawing at insulation.

  • Diseases and infections : Rats spread leptospirosis, salmonellosis, and other dangerous diseases.

  • Unstable heating : damaged systems can disrupt the heating performance of a building.

How to recognize the presence of rats?

  • Sounds of squeaking or running are heard behind the walls;

  • Bite marks on insulation, cables or pipes;

  • Stool and specific pungent odor;

  • Collapsed sockets or paper cuts.

Prevention measures:

  1. Seal entry points – especially around pipes and vents.

  2. Ensure cleanliness – no debris or water accumulation.

  3. Regularly inspect technical rooms - early detection of signs helps prevent major damage.

  4. Use professional measures – rodent control stations, traps or repellers.
