Report rat infestation - Tips to avoid rat infestation

Information about what to do if you have detected/observed a rat infestation.

According to § 2 No. 12 of the Infection Protection Act, rats are health pests because they can transmit pathogens to humans.

Rats, like other animals, usually occur where they find sufficient food, shelter and nesting opportunities. Your feces and urine lead to odor nuisance and health hazards.

If you have detected a rat infestation, it is important to note the following:

  • In principle, the property owner, beneficial owner and other owner of land, residential and commercial premises, ships and other means of transport is obliged to detect and control rat infestation. You must immediately notify it to the competent authority in whose area the infestation occurred.
  • According to § 17 of the Infection Protection Act, the competent authority must take or order necessary measures to combat health pests. Control shall include measures to prevent the occurrence, reproduction and spread and destruction.

Help to sustainably reduce the number of rats living with us so that a rat infestation does not occur in the first place:

  • Keep the waste bins tightly closed. Have defective waste bins repaired or replaced.
  • Dispose of garbage exclusively in the designated waste bins never next to them.
    Store the yellow bags out of the reach of rats until regular collection.
  • Dispose of food waste in the organic bin, not on the compost or in the toilet.
  • Do not leave any food source intended for pets or birds open uncontrollably.
  • Pay attention to hygiene and cleanliness in your living environment. Close open areas of any kind (such as openings for ventilation) near the ground with close-meshed grids so that rats cannot enter the buildings.
  • Do not feed animals in parks, green spaces or in public places. The remaining remains are a found food for rats.


In addition to rodents (e.B. wandering rats, domestic rats and house mice), vermin (arthropods, e.B cockroaches, flour moths, bacon beetles) also belong to hygien pests that contaminate food and / or buildings, destroyers of supplies and food and ultimately also cause technical defects.

§ 2 No. 12, § 17 Act on the Prevention and Control of Infectious Diseases in Humans (Infection Protection Act - IfSG).

According to § 17 paragraph 5 of the Infection Protection Act (IfSG) in conjunction with Article 1 paragraph 2 of the State Ordinance on the Transfer of Authorisations and Provisions of Responsibilities under the Infection Protection Act (IfSGErmÜV), the districts / the district-free cities can issue corresponding ordinances.
