Quick and effective extermination of Prussians in an apartment


After getting rid of red cockroaches, do not rush to celebrate your victory. Take care that they do not enter your home again. The appearance of Prussians in a house or apartment is a real disaster. People have been fighting these beetles for years, but victory remains theirs, despite the huge losses in their ranks. Many desperate residential property owners have a question: why, despite all the means used, they cannot get rid of these annoying insects; how to get rid of the Prussians once and for all? If this question is considered comprehensively, then the answer is not difficult to find.

Cockroaches don't like cleanliness

Prussians (red cockroaches) are living creatures, they need to eat something. If there is something to eat in the kitchen, they will always find ways to get to their food base. Before starting the next military operations against them, you need to assess the sanitary condition of the room where food is prepared.

  • There should be no leftover food, bread crumbs, or containers of liquid left in the kitchen overnight. All products should be placed out of reach of insects or packaged in plastic bags.
  • Don't forget about the trash can. If the family does not have a rule to take out the garbage in the evening, then the bag of garbage should be tightly tied.
  • Floors must be kept properly clean. The presence of crumbs on the surface is unacceptable.

A clean kitchen will not be attractive to Prussians; there will be fewer of them. But, of course, they will not disappear completely. However, now the fight against these insects will be more successful.


Prussians cannot stand the smell of ammonia. If you add a few drops to a bucket of water and wash the floor or wipe the places that the described pests especially love, then these insects will leave you for a while

Reasons for appearance

When you find cockroaches in your home, it’s worth thinking about why they settled in your apartment. The answer is very simple - optimal conditions have been created for the habitat of these insects, namely:

  1. Affordable food. This could be crumbs on the kitchen counter, cereal spilled in a kitchen drawer, or open garbage bags. A cockroach can feel quite normal even if it eats once within 3 days. Therefore, if you sprinkle a handful of flour, it will be enough to feed a colony of Prussians for several weeks.
  2. Water is freely available. Cockroaches, like any living creatures, cannot survive without water for long. Therefore, they can often be found in the sink at night, where they are content with drops of moisture on the walls or bottom of the sink. And, if your faucet is leaking a little, then this is a real abundance of water for the red insect.
  3. Neighbors have food and water for cockroaches. If you have careless neighbors who do not clean the apartment, then you will not be able to get rid of cockroaches alone. We'll have to try to join forces with them in the fight. In the event that the neighbors do not want to engage in a joint fight, the only option left for you to limit the inter-apartment migration of insects is by sealing all the cracks and cracks in the walls, ceiling and floor of your apartment.
  4. Warm. Prussians are not adapted for living in cold rooms, so they live only in heated dwellings. And, if these rooms have places for shelter, food and water, then this place looks like a real paradise for cockroaches.

Important! Fighting the Prussians in an apartment building will not be successful if you fight them alone. Only by uniting with neighbors can this complex problem be solved.

What is sold in stores from the Prussians

It is easier to kill cockroaches in a private house than in an apartment, since they do not escape from neighboring apartments, through ventilation grilles or other means available to them.

Poisoning insects in the house and apartment

Poisoning insects in a house or apartment can be done using different methods. The following methods are effective:

  • treating the room with borax, its alternative is boric acid;
  • freezing of premises;
  • the use of plants and preparations with appropriate components in the composition;
  • the use of products with a very pungent odor, including denatured alcohol, ammonia, turpentine or kerosene;
  • recipes with flour mixed with cement, alabaster or gypsum;
  • choosing traps that are made with your own hands or bought in a store;
  • use of purchased funds.

You need to be careful with chemicals, as they can be dangerous to humans. They should be avoided in cases where children or pets may have access to them. The use of chemical poisons can have a negative impact on household members. In this case, the optimal solution is folk remedies. However, you should not expect a miraculous result. Prussians are the most difficult insects to remove.

What is more effective against Prussians?

All means available to the buyer for exterminating cockroaches have their advantages and disadvantages.

  • The aerosol product will destroy all individuals in the house very quickly. But after treating the premises with insecticides, all residents will need to move somewhere for at least one day. Then you will need to thoroughly clean your apartment or house. The aerosol product is suitable for combating large numbers of Prussians.
  • If the Prussians manage the kitchen in small quantities, you can limit yourself to a pencil, powder or gel. When using these products, there is no need to leave your living space. But their validity period is longer. They are especially effective if you need to free a specific place from the presence of cockroaches, for example, a bedside table, pantry, closet, etc. Then just draw a line with a pencil or gel, and uninvited neighbors will no longer visit this place.
  • Traps are used when there is a small concentration of insects. They are equipped with bait, the smell of which attracts insects, and Velcro, upon which the pests die.
  • The most drastic way to rid a living space of Prussians is to call a pest control service. But due to the high cost of professional services, people rarely order them.

If we talk about the cost of all the above products used to kill insects in an apartment, then the price of an aerosol in comparison with gels and pencils used for the same area is much higher.


Traps are used when there is a small concentration of insects

The Mashenka pencil earned good reviews from consumers. People like it because of its affordable price, safety and ease of use. This is a fairly effective remedy if the problem with the Prussians is not global.

Freezing the premises

Freezing a room is one of the most effective methods. People have used it at home since ancient times. Its effectiveness is explained by the fact that the Prussians originally originated from hot tropical latitudes. That is why they can live exclusively in relatively warm temperatures. These mustachioed creatures are completely unsuited to frost.

It is enough to freeze the room at a temperature of -5 degrees. This is enough for the insects to die within 5 minutes. However, if there is a warmer room nearby, then during such persecution the Prussians will run there. That is why it is recommended to freeze at a temperature of -10 degrees, then the insects die after 2 minutes.

To get wet, you should provide a draft in the rooms. To do this, open all windows and doors for 3-5 hours.

This method also has disadvantages:

  • possible damage to household appliances due to condensation accumulation;
  • problems with wallpaper and other finishing materials;
  • possible negative consequences for the heating system.

In other words, this is a rather risky, but very effective way of fighting the Prussians. If other methods are ineffective, it's worth taking the risk.

How to remove Prussians using improvised means

There are quite a lot of people who are afraid and do not trust the ready-made remedies for Prussians offered by manufacturers, so they want to know how to get rid of Prussians without using insecticides.

  • Prussians cannot stand the smell of ammonia. If you add a few drops of water to a bucket and wash the floor or wipe the places that these pests especially love, then these insects will leave you for a while.
  • There is another proven folk remedy that can be used to combat insects crawling around your apartment. You will need: boiled eggs and potatoes, as well as boric acid. Finely chop the eggs and potatoes, add boric acid and make small balls from the resulting mixture.

Poisonous balls should be placed in places where insects crawl. Prussians who feast on such balls die over time. But when using this method, make sure that your poison balls are out of the reach of children and pets.

Step-by-step instructions for exterminating cockroaches

If the pests have already tired you so much that you have decided to thoroughly approach the issue of exterminating them, take appropriate measures. To do this, proceed step by step in this way.

Step 1: Understand the situation

Understand that cockroaches appear in an apartment for a reason. If they have started and, moreover, are actively reproducing, it means that conditions suitable for them have been created.

Important! In the apartment, insects are similar to a human disease. In fact, removing cockroaches can be done quickly and easily. But preventing their reappearance indoors is much more difficult.

Cockroach removal should begin by assessing the scale of the problem. Moreover, not in the apartment, but on the scale of the entire house.

Step 2: Chat with your neighbors

As a rule, it is from neighboring apartments that the infestation of cockroaches begins. Therefore, go around at least 2-3 apartments with which you have common walls. If you get into a rage, go around the whole house. Agree with the residents of other apartments to get rid of the Prussians once and for all at home through joint efforts and targeted comprehensive actions. This way you won’t give pests a single chance.

Step 3. Eliminate the reasons for cockroaches moving into your apartment

This is the most important task. Without solving it, even a powerful insecticide will only work for a short period of time. And by making the room unsuitable for cockroaches, you can ensure cockroach removal at home without additional means and measures.

What will it take? Quite a bit:

  • Remove leftover food out of reach and pack it in a plastic bag.
  • It is important to limit insects' access to leftover food.
  • Wipe sinks and bathtubs before going to bed - cockroaches require regular drinking.
  • Thoroughly clean your nightstands, sweep away any rubbish from under all furniture.

Step 4: Eliminate existing cockroaches

This stage is a step of action as well as result. You can remove cockroaches in different ways and at different times. And for each method there are optimal means and methods. We have already given you information about some of them above. Now let’s give one more example of how to get rid of Prussians once and for all at home.

Freezing cockroaches is an almost ideal solution for those who live in the northern part of the hemisphere and for those who can organize a reduced room temperature lower than minus 8 degrees C without any risk to the plumbing systems.

This operation is incredibly simple:

  1. Open all the windows in your room on a frosty day.
  2. Turn off all heaters.
  3. Leave your apartment to cool down for half a day.
  4. If the frost outside is lower than minus 12 C.

Important! It will take 5-6 hours to achieve the required temperature in the room, as well as the death of insects. To be safe, freeze the apartment for 9-10 hours.

This method has a lot of advantages - safety for people and pets, 0 financial investments, simplicity. Just take care of aquariums and terrariums in advance.

But it also has disadvantages: in heated apartments, the cold can lead to damage to radiators and pipes. At the same time, this method is not available to everyone and not all year round, and this is what significantly limits its use.

Step 5. Make the apartment safe for all other inhabitants

When using any poisonous drugs, take care of the safety of children and pets. Even though a significant part of the insecticides against cockroaches that are sold on the market are not highly toxic, they can still cause various disorders:

  • allergies due to skin contact;
  • diarrhea, as well as vomiting when ingested by the human body;
  • individual reactions.

Rules for using funds to remove Prussians from the apartment at home:

  1. Place products that contain borax and boric acid in places where they cannot be reached by animals and children.
  2. When calling pest control services, carefully follow all their recommendations.
  3. As a rule, each anti-Prussian product is sold with instructions, strict adherence to which guarantees safe and harmless disinfestation.

Step 6. Don't let cockroaches re-enter your apartment

To prevent the re-introduction of cockroaches into your apartment, carefully monitor its cleanliness and sanitary condition. In addition, it will be useful to do the following:

  • Install screens on your vents, or use a roach-proof pencil on the inside of them.
  • Place cockroach traps in the waiting rooms.
  • Use a pencil to draw stripes along the entire outer perimeter of your apartment windows.
  • Give a good and proven substance to your neighbors. But after this, be prepared for the fact that some of the cockroaches will try to escape in a cleaned room - that is, in your apartment.

Don't let your guard down - cockroaches may return

After getting rid of red cockroaches, do not rush to celebrate your victory. Make sure they don't sneak in again. We recommend learning about the types of domestic cockroaches.

To do this, cover the ventilation grilles in the apartment with a mesh with small cells through which insects cannot penetrate. Disinfect the room periodically and be sure to keep the apartment clean, especially in areas where you cook, dine, and feed your pets.
