Why cockroaches appear in apartments: main causes and conditions

Good day! Once upon a time, a couple of centuries ago, people were sure that the mice in the house were made of dust and old rags. Of course, not a single living creature is taken from nowhere.

However, many people sometimes wonder why cockroaches appear in apartments if the house is clean and there are no leftovers. I will show you several options why parasites can choose this or that dwelling, even if it maintains perfect cleanliness!

8 main reasons for the appearance of cockroaches in your apartment

Cockroaches are the most common parasites on the premises. They are able to survive in the most adverse conditions, will settle further. It is important to understand the reason for the appearance of parasites in your home in order to exclude their appearance.

Insect features

Cockroaches are striking in their vitality. In the absence of normal food, they feed on dust, dirt, sweat-dried sweatshirts, fallen hair, glue in binding books, insulation from wires. Not suitable for food only glass, iron, some types of plastics.

Without food, pests can live up to two months. Parasites without water do poorly, one drop is enough for several days. Absolutely without water, the insects will last one week.

Increased radiation levels do not have a lethal effect on domestic pests. In such conditions, they even continue to multiply.

An interesting fact - cockroaches are able to pretend to be dead. But they do it not consciously. A special gene was discovered in the body of the insect that causes the parasite to turn off when it eats poison or smells it.

If a dead-looking pest is found, it is swept into a scoop, thrown into the bin. There the insect comes to its senses, crawls away. That is why it is recommended to wash dead insects in the toilet, do not throw them in the trash!

Conditions for the appearance of cockroaches

Domestic parasites appear in those places where there are comfortable conditions for them. For their nests, choose cluttered places where little sunlight penetrates.

It is desirable that it was damp, there was food nearby. The kitchen has always been a favorite place; it meets all the requirements.Behind the bin near the sink, you can get drunk, eat.

They do not like pests cold, often settle behind batteries, near the stove. Close to the litter of pets (cats, dogs), cockroaches will not settle, do not tolerate such a neighborhood.

They like insects to climb into electrical appliances - televisions, computers, microwaves, toasters. By laying eggs there, complex equipment can be destroyed.

Why do cockroaches appear in a clean apartment?

Sometimes, even in a perfectly clean apartment, home parasites appear. So they came from other places. If there are no comfortable conditions for them, they will not linger.

Domestic parasites constantly migrate. The breeding of cockroaches is around the clock, the new generation needs the territory that you have to look for. Even if the owners are confident in the cleanliness of the house, preventive measures must be taken. Uninvited guests may like the apartment.

Cockroaches in a clean apartment may appear:

• through common sewer or water pipes;
• through general ventilation;
• from the general garbage chute;
• with old things when moving;
• with things of someone who came to visit;
• with postal parcel;
• with the delivery of furniture from a furniture store;
• with things from the trip.

Penetration from neighbors

This is the most difficult case. There are two options. Cockroaches run because neighbors have unsanitary conditions, the insect has become crowded. Another option is that neighbors constantly get rid of parasites who seek shelter in other places.

When neighbors do not want to starve domestic pests, they can be forced to do so in court. First you need to get a document that confirms the unsanitary conditions in the neighboring apartment.

Insects can climb through cracks in the floor / ceiling, cracks in the walls, skirted boards loosely nailed through sockets. They move on the porch, live in attics, in basements.

Penetration through the chute

The best place for cockroaches is considered the garbage chute. This is an abundance of food, moisture, good shelter. They are unlikely to want to run to the apartment from such a comfortable corner, if only too many of them have divorced. Parasites can enter from the garbage chute into apartments to settle in new territories.

For this, a scout cockroach inspects the premises, if it finds it suitable, then several dozen individuals move to a new living space. But the cleanliness, lack of moisture and affordable food may not appeal to the scout.

When moving

Penetration of cockroaches is possible when moving from an old apartment to a new one. So you can capture old residents with your things. It is enough to take the eggs of parasites, and not adults.

When moving, it is difficult to maintain cleanliness. And patient parasites can survive long journeys in poor conditions. They will find for themselves something inedible, but suitable for satisfying their hunger.

Introducing guest things

In some cases, guests with their things bring more insects. This does not happen on purpose, because small parasites do not climb into bags for the purpose of traveling.

Insects are constantly looking for food, water, this leads them to different places, including bags to a person. They crawl out in a completely different apartment.

Do not be afraid that with your hand in your bag, you can stumble upon a cockroach. If he is there, then he hides, does not find his presence.His task is to go unnoticed. Domestic cockroaches are nocturnal parasites. They prefer to go out in the dark, when it is quiet around.

When purchasing used equipment

When buying used equipment, one must be careful. There may be unpleasant surprises in the form of cockroaches or their eggs. It is not clear what attracts parasites in electronic devices but they prefer to live in:

1. TVs
2. system units of computers;
3. toasters;
4. microwave ovens;
5. laptops.

It is very important to remember that to expel the pests of these devices, you can not use household chemicals, folk recipes. Expensive equipment may break.

You can expose it to severe frost or disassemble and clean if there are suspicions of the presence of parasites inside. The microwave oven can be turned on at full power, cockroaches will run away from it.

Brought from a trip

It is quite possible to bring parasite travelers from a business trip, travel, vacation. A female cockroach could have chosen a suitcase or travel bag for laying eggs.

Parasites constantly poison. This must be done by all organizations that deal with products. But cockroaches can appear again if the place is comfortable, and the toxic substances are not too poisonous.

Receive by mail

Currently, online shopping is very popular. They are delivered via mail. This type of delivery can bring mustachioed parasites to the house.

Previously, this is how these parasites settled around the world. So in our latitudes appeared not at all characteristic black, American representatives.

With the purchase

You can bring pests home with products from the store, supermarket, from the market. They can easily get into the bag, wait for the right hour to get out.

When buying things or other non-food items, insects fall into bags by accident. In departments with products can occur constantly. This is especially true for markets that are poorly controlled.

Causes of pest survival

If we succeeded in finding out why cockroaches were started in the apartment, then we need to decide why they take root. Before their penetration there were no such pests, why did these settle?

Usually residents in apartment buildings do not take preventive measures, although there may be nests with domestic parasites nearby. In order to live and breed, a cockroach needs only three conditions:

• food;
• access to water;
• comfortable temperature.

All this is in human habitation. In addition, all the apartments in the house are connected by communications, you can safely move from one to another, traveling through an apartment building, going down to the basement, going up to the attic. If parasites are driven out of one room, they sit out in another, return again.

Why appear again

In some cases, after the treatment of the premises with poisonous agents against domestic parasites, they again appear. The owners blame it on low-quality poison, dishonest work of specialists. Although the reason may be different.

After a certain time, a new generation of pests is born. They scatter around the territory. They are seen by the owners of the apartment, who think that their former cockroaches returned to them.

Ongoing prevention

In a cozy beautiful apartment, I want to live not only for a person, but also for some types of insects - cockroaches. In order not to share housing with them, it is necessary to constantly apply preventive measures, even if parasites have not been seen for a long time, they can appear suddenly. The table shows simple preventative agents against domestic parasites.

Constantly ensuring cleanliness in the house, still sometimes you have to face the appearance of cockroaches. Now knowing the reason for this, you can take measures to get rid of unwanted guests. It’s better to prepare - to take preventative measures, this will protect the house from many pests.

What causes cockroaches and how they penetrate the room

Cockroaches are insects that can survive even an atomic war. The presence of such guests in a house or apartment is unpleasant and requires action, because they are carriers of dangerous infectious diseases and worsen the sanitary condition of the room.

Unpleasant guests are subject to different types of housing: old dormitories, and new multi-storey buildings, and apartments, and private buildings on separate plots, and housing, and industrial premises. We'll figure out where the cockroaches come from and how to deal with them yourself.

Why appear in apartments

An important factor in answering the question of why cockroaches appear in an apartment is the condition of the room. Dirt and debris will surely attract the mustachioed guests, and the cracks in the floor and the wallpaper behind the wall will be an excellent refuge.

The insect remains to live where favorable conditions for nutrition and reproduction are created. The reasons why the cockroaches decided to stay with you:

Availability of free access to water

Individuals are tenacious and can do without food for a long time, but they just need fluid daily. If plumbing is faulty in the house, wet rags and sponges are on the sink, condensation appears somewhere, water is dripping from the tap or pipes are leaking, and indoor flowers are in trays of water, such conditions will be perceived by insects as ideal.

Optimal living conditions

A temperature of 20-23 ° C and an air humidity of 50-65% are comfortable not only for humans, but for most types of cockroaches. The presence of secluded places inaccessible to the human eye will strengthen the desire of guests to stay in the house forever.

Quite often, they hide on the back walls of furniture, under the baseboard, in household appliances, in the cracks of floor coverings, in ventilation ducts, under the sink in the kitchen or in the bathroom near pipes, in grates.

Access to food

Cockroaches are not picky. If there is no treat on the table, they will eat pieces of food on the floor and in the bin. Food and fat, burnt to the stove, food residues in the drain hole, crumbs falling over the kitchen set - all this is perfect for a balanced diet of pests.

A lot of reasons provoke the appearance of unpleasant insects, but compliance with preventive measures will avoid this. A clean and dry wiped sink will ensure a lack of food and the insects will go away.

If the incident occurred, find out where the cockroaches come from in order to plan an effective action. The measures taken in time will stop the increase in the population and drive away the pests.

Where do cockroaches come from and how do they get into premises

Almost every family came across cockroaches, but not everyone understands where they come from. Knowing the reasons, you can protect yourself from trouble.

Insects can start on your territory, regardless of where you live, whether it is a separate section or area in an apartment building.It is important to be careful about what you bring with you.

In the House

People living in the private sector are often perplexed by what causes cockroaches. The house will protect your family from the settlement of the colony between neighbors, but the occurrence of a problem is not excluded. There are several other reasons why cockroaches can start:

1. Shoes or clothing. The guest or the immediate owner, without knowing it, can bring an insect on his shoes or clothes;
2. Food from the supermarket or from the market. Most stores are teeming with cockroaches. Once in a bag or bag, the individual perfectly tolerates transportation and, in the presence of favorable conditions, continues to breed in the kitchen already in the house;
3. Purchase of equipment, furniture and things in places with unfavorable sanitary conditions;
4. Baggage, after a trip and a business trip. Cockroaches are more than frequent hotel guests around the world. Crawling into a suitcase, individuals of insects travel with its owner, from where they climb into a person’s dwelling. Before you go home, check your suitcase and items for parasites and their eggs.
5. Postal items. The spread and mixing of insect species occurred precisely due to the presence of baleen individuals in the mail. A black American cockroach entered the territory of other countries in the package.

It is enough to appear to one female and 2-3 males. If the conditions are favorable for reproduction, and there is enough food and water, then in a week the population will reach several dozen red-headed guests.

In the apartment

In an apartment building, the resettlement of cockroaches is much simpler and faster. Ventilation hatches and slots between the ceilings make it possible to freely move between rooms if necessary.

It is very important to monitor the cleanliness of the entrance and the condition of the garbage chute.

How cockroaches start in an apartment:

• Resettlement of the population from neighbors. The most popular way for pests to enter a home. If there are too many insects in one territory and they do not have enough food or space for laying eggs and raising offspring, they develop new territories. It is important for cockroaches to have a certain area for successful breeding.
• Disinsection in the neighbors. Active sole control of red parasites causes insects to seek refuge in nearby apartments. First, “scouts” set off on a survey of the new area. If the conditions are suitable, then the entire colony is resettled.
• Poor sanitary condition. The main reason why cockroaches start. Availability of conditions for nutrition and reproduction. Crumbs on the table or floor, dirty dishes in the sink, naked foods and wet rags are ideal for the safe existence of uninvited guests.

Cockroaches can periodically appear in the house. They may be near you in the apartment for a long time, but it is not easy to find them until the colony has become too large.

To drive pests out of the equipment, you can turn on the device for heating for half an hour, remove the equipment to freeze or put a cotton wool soaked in boric acid into the device.

If the living conditions are unbearable, and there is not enough space for breeding, the insects will go looking for a new home, examining all the nearest apartments.

In order not to become a victim of the mustachioed guests, it is enough to adhere to cleanliness and not leave water and food in the public domain.

In a couple of months, small cockroaches will turn into prolific adult individuals and continue to multiply a colony of relatives.

How to get rid of at home

You can avoid the emergence of such “friends” using preventive measures, so you should know why cockroaches start.

1. Perform general cleaning at least once every 2 weeks, use disinfectants for surface treatment. Pay particular attention to inaccessible places;
2. Coat all possible cracks and cracks, glue the wallpaper;
3. Throw out garbage at least 1 time per day, cover the bucket with a lid;
4. Do not leave dirty dishes. Wash plates and utensils after each meal;
5. Clean the sink and drain every time you use. Dry rags and sponges well;
6. Clean the stove after each cooking. Old fat on the hob or in the oven is a favorite treat for cockroaches;
7. Do not leave food and water in the public domain. Keep all possible foods in the refrigerator. Wipe the surface dry before putting the washed dishes into the cabinet.
8. Dry the bath and sink overnight before going to bed, as cockroaches often lead a nocturnal lifestyle.

What to do if cockroaches are already wound up

If the trouble has not passed you, you should immediately begin to take measures to eliminate it. Bring the sanitary condition of the apartment or house in perfect condition.

Use traps to kill the population. Make them from matchboxes. Leave a small gap. Once in a secluded place, the cockroach will not be able to get back. All that remains is to dispose of the boxes.

Add boric acid to bait or water, place in places of occurrence. For pets and humans, this remedy does not harm, and cockroaches after it will not be able to survive.

The chemical industry offers effective methods for home use. Crayons, sprays, aerosols, powders, gels with insecticides will scare off and destroy the cockroach colony, but the egg clutches will remain intact.

It is necessary to use the poison according to the instructions for use. When poisoning, avoid places where children and pets can enter.

Other traps work on the principle of adhesive tape. When hunting for a tasty bait, the cockroach gets into the sticky composition, which processed the trap from the inside. Sometimes their use is most convenient, because Suitable for any area and sold in every store.

Conclusion

Cockroaches can be the source of such serious diseases as tuberculosis, hepatitis, tetanus, etc. If you find only a couple of individuals, take care of the sanitary treatment of the room, check all ventilation hatches for nets, set traps and poisonous baits.

When you can’t cope with pests yourself, you need to contact professionals. An experienced disinfector will help get rid of uninvited guests quickly and efficiently. Strong insecticides will discourage insects from visiting your home for a long time.

If the cockroaches still come back, fight together with your neighbors, only in this way you can overcome the problem.

Remember that prevention is the best way to prevent the appearance of red-headed guests.

Where do cockroaches come from?

There are several ways for pests to enter a house:

• From the neighboring apartment. Cockroaches often populate new areas after pest control. Insects make their way through garbage chutes, ventilation passages, through cracks and crevices in the walls.
• With things.Household items, appliances, clothing brought from a business trip or used by friends often become a haven for fertilized female cockroaches. In the presence of suitable conditions for reproduction, even one individual is able to give life to a vast population of pests.
• With shopping. Cockroaches are able to quietly climb into a grocery bag or bag both in the store and on the market.
• With the package. A means of transporting cockroaches can be goods ordered via the Internet. It is proved that the development of the sphere of services for the delivery of products from continent to continent is one of the main reasons for the resettlement of exotic insect pests throughout the globe. This is the answer to the question of where the large black cockroaches come from in the apartment.

Risk factors

There are a number of unfavorable factors that contribute to population growth and the preservation of cockroach colonies in the house. First of all, it is worth noting the unhindered access of insects to food.

As practice shows, cockroaches are extremely illegible in food. For their propagation, the presence of breadcrumbs, rotten garbage, etc. is enough.

But! It’s hard for cockroaches to do without water. In apartments, any source of moisture concentration can serve as a source of drinking for insects.

This may be insufficiently tight joints of the water supply system, puddles on the floor, kitchen items, a wet sink and the like. In case of blocking access to the alleged sources of water, pests often get it from the ground, which is located in flower pots.

After finding out where the cockroaches come from in the apartment, try to regularly wipe the damp surfaces, and also water the indoor plants early in the morning so that the liquid has time to properly absorb into the soil at dusk.

In conditions of maintaining a stable microclimate in the premises, cockroaches feel great, waiting for the daylight hours in dark nooks and crannies. On the contrary, a temporary decrease in temperature even to -1 ° C can significantly reduce the number of insects in the house.

How many cockroaches live

Cockroaches are extremely tenacious creatures. In the presence of comfortable conditions, adults are able to exist in the house for a year and a half. Large black cockroaches can do without food for up to 40 days.

However, as already noted, it is quite difficult for them to live without water. Usually insects, which are tormented by hunger and thirst, become extremely aggressive, eating relatives. Often, the deterioration of living conditions leads to the fact that pests begin to bite pets and even people.

In the latter case, insect respiration and fluid intake occur through special pores on the abdomen. Therefore, the physical impact on cockroaches does not always lead to their death.

Cockroach Control Methods

Among the most effective solutions that contribute to the destruction of insect colonies, it is worth noting the following:

1. aerosols;
2. traps
3. toxic bait;
4. folk remedies (ammonia, boric acid, arsenic).

Aerosols

Such aerosol products have proven themselves well in the fight against cockroaches: Raptor, Raid, Dichlorvos Neo, Extrazole. These drugs are quite expensive.

However, the costs in this case are fully justified, because cockroaches quickly get used to the smell of cheap aerosols. In addition, unverified funds can be harmful to human health. Be that as it may, when treating the premises with aerosols it is recommended to leave the apartment for a while.

Toxic bait

In this category of insecticides, bulk and gel-like toxic substances are presented. And it’s not so important where the black cockroaches come from in the apartment.

You can use “Absolute-gel”, “Dohloks”, “Raptor-gel”, “Trap-gel”, “Adamant-gel” for area processing. These drugs are more effective than aerosols.

Proper placement of toxic baits in the apartment containing a small amount of loose or gel-like substances makes it possible for a long time to forget about annoying "neighbors".

Trap

Special traps are the most innovative and extremely effective means in the fight against small baleen pests.

Falling into a trap through small holes, pests not only eat poison, but also collect its particles on the body, later infecting a colony of relatives.

Having determined where the cockroaches come from in the apartment, you can place another type of trap in the distribution points - in the form of labyrinths.

Once inside this device, the insect moves along the tangled corridors on the way to the food bait (not necessarily toxic).

The absence of a light source and the presence of food makes the cockroach remain in the maze, where, in fact, it dies without water in a few days.

Folk remedies

The use of chemical insecticides to control cockroaches entails the spread of unpleasant odors in the premises, as well as toxic substances that are potentially harmful to human health.

Given these nuances, some homeowners prefer the following proven folk methods of controlling insect pests:

• Boric acid. About a teaspoon of the chemical is mixed with a hard-boiled egg (take the yolk). The bait is prepared in the form of small balls, which are laid out in potentially dangerous places, that is, where the red cockroaches come from in the apartment.
• Ammonia. A small amount of this product is added to mopping water. A thorough cleaning of baseboards and alleys is carried out, in which large cockroaches can live (where small individuals come from in the apartment, probably you can not explain).
• Arsenic. Powdered chemical mixed with icing sugar. The prepared composition is scattered around the perimeter of the premises infected with pests. After a few days, the floors are thoroughly washed. At the same time, it is important to exclude the ingress of poison on household items, food, dishes.

Preventative measures

To prevent the re-distribution of cockroaches in the apartment, you should adhere to such rules:

1. conduct regular high-quality cleaning of housing;
2. empty the bin until it is completely filled, pull a piece of plastic film tightly over the edges of the container;
3. hide food in the refrigerator, remove leftover food from the table;
4. thoroughly wipe the sink, bath, surface in the bathroom from moisture during the period of disinsection;
5. seal cracks, cracks in walls and ceilings, which can become a habitat and movement of cockroaches.

Finally

If the owners have figured out where the cockroaches come from in the apartment, everything should be done in order to expel uninvited guests and prevent their repeated invasion.

To neutralize insect colonies, it is worth closing all the cracks in the house, isolating the ventilation ducts, and after the destruction of the pests, it is recommended to monitor the sanitary condition of the premises.

All this will make it possible to forget forever what cockroaches are, where small "parasites" come from in the apartment and how to deal with them.

How and where in the apartment appear cockroaches

Cockroaches in the apartment - a problem that is familiar to many firsthand. These insects are the most common pests in apartments, houses and utility rooms.

And although cockroaches do not harm a person directly, they are extremely undesirable insects in the house, contributing to the spread of diseases and generally worsening the sanitary condition of the home.

How and where do cockroaches enter the room?

The owners of the house, who discovered unpleasant insects in their kitchen or in the bathroom, first think: where did they come from? In fact, there are a lot of ways for these parasites to enter the house. We single out the main ones:

• From the neighbors. Cockroaches can leave their former home en masse after being harassed or accidentally enter a new apartment through ventilation ducts, a chute, through cracks in the walls. If they are satisfied with the amount of food and drink, as well as the ambient temperature, then cockroaches will willingly settle in a new place.
• With shopping. A cockroach may well end up in a bag or shopping bag in a market or store. It happens that the insect "moves to a new place of residence" right in the purchased things: household appliances (computer system unit, microwave), furniture or clothes. Of course, a cockroach can get into such products only by accident, because they do not represent nutritional value for it. But in grocery stores it can be found very often.
• In things. Things brought from a business trip or used by someone can become a temporary shelter for a female cockroach, which will give life to a whole population of parasites.
• With the parcels. Nowadays, purchases via the Internet, which are delivered by mail parcels, are very popular. These parcels, especially from abroad, can become a "transport" for cockroaches and other insects. By the way, it was the development of communication routes between different countries and even continents that became the main reason for the settlement of cockroaches around the world. Now in our latitudes you can meet not only the red-haired kitchen cockroach “Prusak”, but also the black one, as well as the huge American cockroach.

A little more about the causes of cockroaches in the house

If everything about where the cockroaches come from in the apartment is more or less clear, then the reasons for their successful “fixing” and breeding in the room are not so obvious to most of us.

Cockroaches are insects that require a certain area to settle a population. If there are already too many cockroaches in the infected apartment and there is not enough food for everyone, some of them are sent to neighboring rooms in order to develop new territory.

If cockroaches appeared in the apartment, another option is possible: the neighbors are doing their best to get rid of the parasites, creating unsuitable living conditions.

Naturally, cockroaches are urgently trying to leave the apartment and move to a new, safer place of residence. In such cases, cockroaches usually migrate en masse, immediately populating the neighboring apartment with the entire surviving population.

Sometimes cockroaches populate a room from a female or a pair of cockroaches accidentally entered earlier. Most often, this problem occurs in people who travel a lot or go on business trips, staying in various hotels. Sometimes cockroaches get into the house with food purchased at the supermarket.

Cockroaches in the house - a sign of unsanitary conditions

Regardless of the cause of the appearance of cockroaches, the preservation and increase of their population is possible only if there are a number of favorable factors:

1. Free access to food. Cockroaches are very unpretentious creatures. They can eat not only fresh high-quality products, but also rotten garbage, paper, leather. A cockroach can do without food for a long time - up to several weeks. But even if you leave an uncleaned table, stove, dirty bin in the kitchen - this will be enough for the normal nutrition of a whole colony of pests. Therefore, to counter insects, you need to literally achieve the ideal order, hide all food at night and take out the trash every day. Cockroaches are mostly nocturnal, so it’s important to hide all food sources before going to bed.
2. The presence of water for drinking. The most important thing without which cockroaches cannot survive long is water. In modern apartments and houses there are a lot of sources. It can be a small puddle on a table or stove, a wet sink, a leaking tap or condensation of water on the tile. If all sources of water are carefully shut off, cockroaches can drink water from flower soil. Therefore, during the period of combating parasites, you need to water the flowers only in the morning or afternoon, so that the liquid is well absorbed. It is recommended to wipe the sink in the kitchen and bathroom with a dry cloth at night.
3. Comfortable room temperature and the presence of nooks. Ideal conditions for life - these are the reasons for the appearance of cockroaches in the apartment. Human housing is perfectly suited to the needs of these insects: it maintains relative humidity and warmth comfortable for them, there are many nooks where cockroaches can hide during the day. In addition, neighboring apartments are not isolated from each other, but are connected by communications, through which insects can freely move.

Often it remains unclear where the cockroaches came from, because there can be many options. However, these insects can continue to live and multiply only in conditions favorable to them.

Typically, cockroach infection begins with several individuals that become the ancestors of a whole population that occurs literally in a few weeks. Unsanitary conditions in the apartment are the main factor in the comfortable life of cockroaches.

By the way, after disinsection, cockroaches can return only if the owners do not care too much about the cleanliness of their home.
