What to do when black cockroaches appear in the house?

Garbage disposal and uncleanliness of your neighbors are the main reasons for the appearance of parasites in your home. Even if you maintain perfect cleanliness in the apartment, do not leave food on the table and monitor the health of the plumbing, black cockroaches are sure to will visit your home. Propagating very intensively, they are constantly in search of new sources of nutrition, so it is necessary to display them by joint efforts.

Black cockroach, like him red relative (Prusak), and overseas brother - american cockroach, refers to home cockroaches. The number of black cockroaches is growing somewhat slower than the Prussians. This is due to several factors:

• these insects are cannibals and can eat eggs left by the female unattended;
• their puberty comes much later than that of a red cockroach.

But this does not mean at all that when they appear, you can behave lightly, since large colonies will appear soon. It is necessary to act immediately. Adults can reach about three, sometimes five centimeters in length and emit an unpleasant odor. They move very quickly, which makes them difficult to capture mechanically.

Important! A black cockroach is capable of causing quite serious damage, not only to your health, but also to utilities - individuals can damage the electrical wiring and disable kitchen appliances.

Do not forget that parasites come to your home after visiting sewer drains, garbage bins and cellars. On their paws they carry a huge number of pathogenic bacteria, the presence of which can adversely affect not only your health, but also the health of your children.

How to recognize

As mentioned above, black cockroaches are impressive in size and exude an unpleasant characteristic aroma. They have a hard chitin cover, painted black. Crushing an insect is quite problematic, since the shell is very durable and serves as a reliable protection for parasites.

Cockroaches have a flat body, and this structural feature helps to easily hide in narrow crevices, which makes them inaccessible to humans. Females differ from males by short elytra, which do not reach the base of the abdomen, and the presence of two folds on the last segment of the body.

Habitat

Black cockroaches are found both in apartments and in the wild. But in the latter case, their habitat will always be close to a person’s home. They prefer to settle in heated rooms, coal mines, sewer manholes, garbage collectors and basements.

In nature, they settle mainly in secluded places. They are attracted by cracks in old buildings and cracks under the stones. And since they are heat-loving insects, in the southern regions they can be seen most often.

In the daytime, they hide in their shelters, and when it gets dark they get out of shelters and begin to search for food.A black cockroach is omnivorous and can consume both ordinary food products, and the remains of its relatives and even the corpses of some vertebrates.

Methods for killing parasites

As soon as a person began to realize that black cockroaches do huge harm, he immediately wondered how to get rid of these insects. We can immediately say that the modern market is full of various drugs for their destruction, so this task is quite feasible. It is enough to familiarize yourself with the basic methods of struggle and choose the most suitable.

Mechanical way

Mechanical extermination involves the use of improvised means - slippers or a vacuum cleaner. But in this way you cannot destroy large colonies.

• Firstly, to see them, you need light, but, as you know, cockroaches are mostly nocturnal. In addition, they develop incredible speed, so even if several individuals appear in the field of view, not all will be able to kill.
  
• Secondly, their chitinous cover is very strong and it is quite difficult to kill an insect from the first attempt with a slipper or a twisted newspaper.
• Thirdly, young eggs will hatch soon from the laid eggs that the females securely hide in places inaccessible to humans, and a new invasion of parasites will await you.

Heat treatment of the room

Cockroaches die at low temperatures. The critical point for them is -10 ° C. Insects lose their ability to move and soon die.

But this method can be applied only when the street is cold. In the summer months, this task is not feasible. In addition, in houses with central heating, freezing cockroaches is not technically feasible, since penetration of too low temperatures into the room can cause serious problems - sewer and heating pipes will simply burst.

Natural repellers

Popular methods of disposal include the use of natural repellents. These include bay leaves, flowering rye, feverfew and elderberry. All of them have a sharp aroma that should scare off the parasites.

But practice shows that this method is ineffective. Perhaps a large black cockroach does not respond to these smells or, over time, acquired immunity to them, since quite often parasite columns are quietly marching around the apartment, stepping over the spread out bouquets.

Trap

Two types can be distinguished parasite traps - These are folk home-made and modern purchased.

Hand-made traps can look like this:

• glass jar, the neck and walls of which are lubricated with some kind of oil. An edible bait is placed inside. Climbing into the jar, the cockroach eats a treat, but can’t get out again;
• sticky trap - the same can, but instead of oil, an adhesive mass or a sheet of thick paper is applied, on which double-sided tape is glued around the perimeter. The principle of operation is similar to the previous one - the insect gets into a trap to eat the bait, sticks with all its paws and loses its ability to move.

Traps of the modern type can act as follows:

• kill insects by the discharge of electric current;
• have a poison bait inside;
• the mechanism does not allow the parasite to get out.

Insecticides

The action of chemicals is directed to the body of an insect. After direct contact of the parasite and the insecticide, he dies. The modern market can offer a huge selection of such tools, among which:

• aerosols;
• dusts;
• gels.

Each of the species has distinctive characteristics and impact characteristics. They resort to them when all of the above methods are ineffective.

Important! Inadequate use of these funds can lead to the fact that cockroaches will gain immunity, and serious damage will be caused to their own health. Therefore, it is always necessary to study the instructions and follow all the rules of use.

The most popular aerosols:

• Raptor
• Raid;
• Combat
• Get
• Sinusan;
• Tetrix.

All of them are characterized by a high speed of defeat. The poison enters the body of the insect along with air and causes its immediate death. Modern aerosols can be flavored or completely odorless. Spraying them is very convenient and simple, besides there is no need to pre-dilute the concentrate.

Gels are more effective. They enter the digestive tract of the insect and kill it. These funds are of low risk to human health and are relatively inexpensive, which allows you to test several brands. The most popular are:

• Storm;
• Fas
• Globol.

Dusts are crayons and powders. For example, crayon "Mashenka". He paralyzes the insect, but is unable to cope with a large invasion of parasites. This means you can mark the boundaries of the territory where the cockroach should not fall, but no more.

Advice! Remember, after using any chemical, care must be taken that insects do not find water. Even a single drop will help to neutralize or weaken the effectiveness of the poison that has entered the body.

But even if you managed to drive the hordes of black cockroaches out of your apartment - you should not relax. They will quickly find shelter in the kitchen next door and after a while they will come back to you again. remember, that bullying must be carried out jointly. Without the support of neighbors, you simply physically cannot completely exterminate the parasites, and all your efforts will have a short-term effect.

Coordinate actions with all the residents of the house, and it is better to invite specialists who, using reliable proven methods, will permanently rid your house of harmful insects. Disinfestation workers will harass not only the living rooms, but also the garbage collector, as well as the basement. Only then will you gain confidence that you will never see black cockroaches in your home again.
