Effectively Pursuing and Fighting Rats in the House

Most people have a natural aversion to rats. No wonder, because the small rodents can bring parasites into the house, transmit diseases and damage the equipment and the electrical wiring in the house. In this guidebook, we'll tell you what you can do to prevent rat infestation in the house.

How to detect a rat infestation

A clear sign of rat infestation in the house is fresh feces. A single rat excretes about 40 bugs each day, which are typically spindle-shaped. Especially if the feces are still shiny and soft, there is an active infestation. Often a pungent odor of ammonia and the finding of dead animals indicate a considerable attack of the rat.

How do rats get into the house?

In Germany, it is primarily the wandering rat and the house rat who invade houses and their houses Mischief. Both species are good climbers. The brown rat can also swim well, which is why she often lives in sewers and penetrates into buildings. Joints, cracks and door cracks are suitable loopholes for the small rodents. They often settle in dark areas such as elevator shafts, attics, and cellars.

Preventing rat infestation with structural measures

The best way to prevent rat infestation is therefore to eliminate all access for small rodents:

  • Close Door Gates with Rubber or Brush Seals
  • Attach Fine Mesh Lattices to Air and Light Shafts
  • Gasket Ceiling and Wall Breakthroughs through which Lines and Tubes Run Clean
  • Install Back Valves with them the rats can not enter the house through the toilet.

All other drains, such as those found in some basements and laundry rooms in the ground, should be secured with a grille.

Rats are best used with live and non-domestic animals Fighting Traps

Once you find that you have one or more rats in the house, you should act before the animals multiply and turn into a mas sive infestation is coming. In some animals it is still possible to use punch and life traps. These are available at hardware stores and in specialized shops.

Rats like to use the same paths again and again. Therefore, you should place the traps where you have found smears or feces.

Basically, traps are always the better solution than biocide products. However, they can lose the effect of a larger infestation, because the animals are highly intelligent and no longer accept the bait. Then it helps to change the bait and choose a different location for the traps.

Rat venom should only be used by professionals

You will hardly be able to eliminate a massive infestation simply by using traps. Many consumers then resort to poison, which is not dangerous. The effect must occur with a time delay, so that the surviving rats are not able to associate the death of the conspecific with the eating of the bait. Effective rat poison therefore works with anti-coagulant substances that kill the animals after a few days.

Many rat poisons contain biocides that are not allowed to be used by private consumers. This applies to Difenacoum, Brodifacoum, Difethialon, Flocoumafen and Bromadiolone. Nevertheless, they are sold in free trade. On the packaging, however, it can be read that only professionals with proof of competence may use them.

For private users, only poisons that are active with warfarin, sodium warfarin, chlorophacinone or coumatetralyl are authorized. However, they are also associated with significant risks. Although bitter substances are often added to prevent pets or children from taking in the baits, secondary poisoning is possible. Your pets or other wildlife may eat a poisoned rodent before it dies from the effects of the poison, poisoning it and, in the worst case, dying from it. Therefore, we recommend using a professional pest controller with poison for rat control who has the appropriate expertise. This reduces the risk to humans and animals.

Which home remedies help rats?

Not infrequently, various home remedies are recommended, with which it is supposed to be possible to expel rats. It is clear that many cats prove to be good rat hunters. They are helping to stem existing rat infestation in rural areas.

There are some home remedies that are supposed to drive rats out of the way, as they disturb the animals' sensitive sense of smell. Recommended are, for example, essential oils, cloves, mint, turpentine, cayenne pepper and chillies.

The actual effectiveness of the home remedies is not proven.


The best advice against rat infestation in the house is, with structural measures Prevent and ensure that the rodents do not get inside the house. For the elimination of individual animals, bats and live traps are well suited. Rat venom should only be used by professionals with proof of competence, as it poses a number of risks for humans and animals.
