Boric acid against cockroaches firmly ranks first or second in the conditional ranking of the most effective and available funds fight against apartment "Prussians". Only special Chinese “pencils” can compete with the folk recipe in terms of effectiveness, which, unlike the relatively harmless and clean pharmacy “boring”, are made from unknown ingredients, often from products of processing chemical waste and toxic substances.

If you have to choose, it is better to use a cockroach repellent with boric acid than, who knows, with traces of mercury or lead salts.

Causes of pests in the apartment

Sanitary and epidemiological station specialists, professional insect fighters and simply sellers of insecticides unanimously claim that the reason for the appearance of cockroaches is unsanitary conditions, improper storage of food and untimely removal of garbage and food debris.

At least three more conditions must be added to unsanitary conditions:

• The presence of free water, which is extremely important for maintaining the metabolism of the insect body;
• Problems with sewer lines. Putrid fumes, traces of sewage leaks, places with the characteristic smell of missing food attract cockroaches like a magnet, even if the room is treated with the product;
• Devices with built-in open electric and gas heaters. A cockroach needs warmth, just like water and food.

Heaters most often become nesting sites for insects, even if the apartment is cleaned fairly regularly and food is carefully stored. Cockroaches have a good chemical memory, finding their traces even several weeks after spring cleaning premises.

Therefore we have to look chemical substances, capable of influencing the metabolism and chemistry of cockroaches. By the best means Preparations based on siloxanes are considered, but they are too expensive compared to boric acid.

Effects of boric acid on cockroaches

Formula boric acid H 3 BO 3 is a white crystalline powder with a slight antiseptic effect, most often used as an additive to an alcohol solution to enhance the antimicrobial effect. Pure boric acid is relatively safe, although if used uncontrolled, it can cause burns and severe irritation of the mucous membranes.

When powdered boric acid enters the body of a cockroach, the weak and non-toxic acid base has a dual effect:

• Partial binding of water occurs in the tissues of the insect, which leads to dehydration of the body;
• Boric acid 100% destroys the microflora, bacteria and fungi present in the digestive tract of the cockroach, destroys the senses and the ability to smell in the first place.

Important! An acidic solution, as an antiseptic, with a weak overall effect, is highly effective against a certain type of microorganism, the death of which leads to the death of the cockroach.

Many experts claim that boric acid burns the chemical marks or memory the cockroach leaves on paths in its habitats. How more cockroaches They spread boric acid along the paths, the greater the chance of their effective destruction.

Cockroach poison with boric acid

You can win the fight against cockroaches only if all residents apartment building actively participate in the process chemical extermination"Prussians". If there is at least one apartment left with unsanitary conditions and cockroaches, the effect of using the poison will be much less, and you will have to use the product constantly.

Cockroaches need warmth and moisture, their body is 40-50% bound water, so the insect can be killed much more quickly effective way. A private house, occupied by cockroaches, are cooled down in winter so that the room temperature drops to 7-10 degrees below zero. If you combine frost with boric acid poison, you can forget about cockroaches seriously and for a long time.

When using bait, you should remove all sources of water from the room, blot condensation in the bathroom, and dry wet shoes from the street in a box with a tight lid.

Boric acid with egg

One of the most popular recipes for boric acid poison is prepared using the white or yolk of a chicken egg.

One egg is boiled until soft-boiled, the shell and cooked white are carefully peeled. Add 10-15 g of dry powder to a semi-liquid yolk, mix into a dough, roll out a thin layer on wax paper and dry to a firm consistency.

It is best to cut a leaf with an acid-based poison into ribbons or small squares. The prepared bait is pinned on cockroach paths using invisible pins or wallpaper tacks. If there is no moisture or drafts in the places where the poison is placed, then you can simply spread the bait on the floor.

After about three days, the poison based on the acidic mixture must be replaced with a fresh one; as soon as the yolk weathers and dries, the cockroaches will stop reacting to it. Do not use a mixture of egg and chemical in its pure form, without paper base, the remaining mixture will only ruin the floor covering over time.

Boric acid with potatoes

According to some experts, cockroaches prefer mainly a carbohydrate and protein base, if possible moist. The bait made from yolk and acid powder dries quickly and loses its attractiveness, so to enhance the smell, carbohydrates are added to the composition, preferably grated boiled potatoes with a small addition of boiled yolk.

Raw grated and squeezed potatoes, mixed with 10 g of boric acid and an egg, have a better effect on cockroaches, but their shelf life is only a few hours, or half a day at most. Then the bait will have to be removed or replaced with a new one.

Boric acid with sugar

Cockroaches, like most insects, love glucose and sucrose in any form. If there is a a large number of sweets, pastries and cakes, crumbs from which can spill onto the floor or covering, furniture, the risk of cockroaches increases by an order of magnitude.

You can prepare a remedy for cockroaches from sugar and boric acid in a ratio of 1:3. Granulated sugar and acid can be ground to powder and the mixture applied to the edge of the baseboard, along the paths under the refrigerator and near the heaters.

Boron bait with sugar, in addition to cockroaches, attracts ants and wasps, so its condition must be checked periodically; if ants appear, the acid with powdered sugar must be removed urgently.

A sugar mixture with boron powder has the best damaging effect, but the bait easily absorbs water, so its use is limited to the kitchen and pantry.

Advice! If it is necessary to enhance the poisonous effect, instead of boric acid, you can use its sodium salt - borax, its damaging properties are several times higher than those of acid powder.

Boric acid with sunflower oil

Cockroach repellents based on sunflower oil and boric acid are used mainly in summer time. The smell of fresh oil attracts cockroaches no worse than carbohydrate and protein bait.

For one boiled and crushed potato, take 10 g of borax, 5-15 g of starch or flour and one tablespoon of oil. The mixture is pounded with a spoon to form a dough, rolled into thin noodles, dried for a couple of hours and laid out in the kitchen.

In winter and autumn, mixtures based on sunflower oil are usually not used, strong smell attracts not only cockroaches, but, first of all, mice. Therefore, getting rid of insects can lead to a serious rodent problem.

Liquid products

A solution of boric acid is more convenient and easier to use; dissolve 25 g of powder in 100 ml of water. Liquid acid mass is used primarily as a supplement to solid bait. After two to three days of a “dry” diet, cockroaches look for sources of water, so a cloth tape soaked in an acid solution kills no worse than branded boric acid against cockroaches.

There is no point in installing saucers or bowls with the solution; “Prussians” usually avoid them, even if sugar is added to the mixture. Acidic poison precipitates as a dense sediment that is difficult to clean up and reuse.

How to make boric acid balls

Even if there are cockroaches in the house, no one wants to walk on bait poisoned with boric acid, so the poison is given a more or less compact form:

• Granules or balls;
• In the form of individual blots or “spots” pasted onto paper;
• In the form of adhesive cords or strips.

The easiest way is to make “piglets”. It is enough to knead a mixture of acid powder or borax with flour and a small amount of sugar, and lay out the mixture in separate blots on a sheet of thick paper. A creamy mixture for cockroaches can be applied to the threshold or baseboard using a large-capacity medical syringe.

To make granules, the dough is flavored with boric acid. sunflower oil, rolled into thin cords, cut into tiny pieces and rolled with a wooden plank to a round shape.

How to poison cockroaches with boric acid

In order to kill cockroaches with boric acid, you must adhere to two simple rules. Firstly, the premises should not be stored in open form no food or water, only bait granules should be available for cockroaches.

Secondly, bait with boric acid in the form of granules and finely ground powder is scattered over the cracks and passages of insects. Periodically, areas with dead insects must be removed and sprinkled with dry boron powder. Crystals of poison stick to the paws, and sooner or later they are eaten by insects.

Boric acid for cockroaches: reviews

The effectiveness of the bait depends not only on a successful recipe, but also on the experience of using the acid mixture in the fight against the cockroach tribe.

Boric acid for cockroaches recipe with egg and reviews about this tool are presented in this article, it is used as poison from harmful insects that have settled in the house. It's very effective means which will be discussed in this article. We'll tell you how to prepare boric acid against cockroaches where to place the poison and how quickly it acts.

Boric acid is not expensive, does not harm home residents and pets, but has a detrimental effect on cockroaches within a week. This time is enough to completely remove these insects from your home.

General characteristics and principle of action on insects

Boric acid has the chemical formula H3BO3, which everyone studies in school in chemistry lessons. This substance has weak acidic properties. Boric acid is a powder in the form of small crystals white odorless and tasteless. Slightly soluble in cold water and soluble in hot water. In nature, this substance is found in the form of a mineral - sassolin, mineral waters and geysers, as well as hot springs.

Boric acid has been widely used by humans: from nuclear reactors to disinfectants. Boric acid is also used as an effective folk remedy anti-cockroach remedy which belongs to hazard class III.

It is used as a basis for preparing insect poison or used in its pure form.

A substance with antiseptic properties is sold in pharmacies in 10 gram bags, included in boric alcohol, which is not effective against cockroaches due to its pungent odor, which repels the insects from the poison. But in powder form, this remedy is simply irreplaceable in the fight against cockroaches, as it is a strong poison for them.

When it enters the pest’s digestive system, the acid is absorbed into the blood and has a paralytic effect on its central nervous system, causing the cockroach to die from suffocation. It is enough for an insect to eat 2-3 mg of the substance, so 1 sachet is enough to destroy an entire colony of Prussians.

For effective fight with cockroaches you can use the following methods:

• use of powder in its pure form;
• preparation of boric acid-based baits;
• the use of solutions of a substance as a poison.

Often, to get rid of cockroaches, it is enough to sprinkle the powder in places where they move: baseboards, under furniture, under the sink. If a cockroach walks through the powder, its particles will remain on the insect's legs. Cleaning its paws with its jaws from contamination, the pest will eat the poison. To achieve maximum effect, it is necessary to block insects' access to water sources. After drinking water, he may not die. In addition, cockroaches cannot live long without water.

To prepare a liquid anti-cockroach agent, dry boric acid powder must be diluted in water and poured into small and shallow containers, which are placed in clean and dry sinks. If there is no other water, the cockroaches will start drinking the prepared liquid.

Advantages and disadvantages of using boric acid

Advantages:

• Cannot harm humans.
• Freely sold in pharmacies.
• Low cost.
• Highly effective remedy against cockroaches.
• Easy to prepare for bait.
• Long validity period.

Flaws:

• Do not place it in places accessible to pets and children.
• Once in the human gastrointestinal tract, it can cause an allergic reaction or poisoning.
• It is necessary to work with it wearing gloves and a respirator.

Edible baits

There are many recipes based on boric acid that can fight cockroaches. You can prepare insect poison yourself at home. All folk recipes based on egg yolk, which neutralizes the odor of boric acid and stimulates appetite in cockroaches.

Important! In order for a cockroach to eat the bait, there should be no food sources or debris in the kitchen.

The poison of boric acid with an egg, according to many reviews, the comma is very effective means in the fight against cockroaches.

Precautionary measures

When working with boric acid without protective equipment, the substance can get on the skin and cause an allergic reaction. the substance can harm a person or animal if ingested only in large doses. In general, boric acid is considered one of the safest insecticides for controlling cockroaches in apartments and houses where there are children and animals. However, do not forget about precautions when working with this substance:

• Wear rubber gloves and a respirator.
• Place the poison in places that are hard to reach for animals and children.
• If the substance gets on the mucous membrane, rinse with plenty of clean water.
• If it gets into the digestive or respiratory system, immediately seek help from a doctor.

Watch the video! Boric acid for cockroaches

Of all, boric acid is perhaps the most famous. There are so many recipes for poisonous mixtures with it that pests can be called true gourmets.

Boric acid is applicable in almost any room and situation. However, for all its versatility, this powder has its own characteristics, positive and negative. Therefore, it is necessary to know how boric acid works even before deciding whether to use it: in some cases it may be more advisable to use other methods.

General properties

Boric acid at normal conditions represents white grains similar to scales. It is odorless and tasteless, melts at 170°C, while gradually losing water and changing its chemical composition.

On a note

Borax is a salt of boric acid, widely distributed in nature. Its formula is Na2B4O7*10H2O. Borax is just as toxic to insects as the acid itself, and a cockroach repellent with boric acid or borax will work equally well.

In nature, the reserves of pure boric acid are very limited. It is part of the mineral sassolin, which is found in small quantities in the Mediterranean and the Middle East. The dissolved substance is present in many mineral waters.

The so-called “boron powder” is a well-known antiseptic, and therefore is sold in pharmacies both in powder form and in dissolved water or alcohol form. It is its solution in 70% ethyl alcohol that is called boric alcohol.

On a note

Boric alcohol is significantly less effective against cockroaches than other forms of boric acid. This is due to the fact that the Prussians are repelled by the very smell of alcohol, and therefore they cannot be poisoned by acid. At the same time, boron powder from cockroaches is practically invisible to them, and the principle of action of the drug is based on this.

The effectiveness of boric acid against cockroaches

For cockroaches, as for most other insects, boric acid is a strong poison. The effect of boric acid on cockroaches is that, once it enters the insect’s digestive tract, it then enters the nervous system through the blood and causes severe irritation of the insect’s peripheral nerves. If the lethal dose is exceeded, the pest becomes paralyzed and dies from suffocation.

Accordingly, for boric acid to be effective against cockroaches, it is necessary for the Prussian to swallow it, and preferably in large quantities by insect standards. Therefore, any remedy for cockroaches with boric acid is used in such a way as to force the insects to eat it, and questions like “How to kill cockroaches with boric acid?” are fundamentally incorrect - these pests do not stain themselves with powder, but poison themselves, so to speak, with pleasure.

It is not at all necessary to prepare boron balls for cockroaches with the addition of eggs, flour, vanilla or other ingredients, enticing them with the smell and taste. In most cases, it will be sufficient to scatter the substance in places where pests often move - near baseboards, along the perimeter of the base of bedside tables, under the sink. After the pest runs through the powder, the particles will remain on its paws. Then, in the shelter, the insect will begin to clean its legs with its jaws and involuntarily swallow the powder itself. With all the emanating consequences.

A solution of boric acid against cockroaches is also quite effective if added to edible baits.

To poison one pest, 2-3 mg of the product is enough. Therefore, a 10-gram sachet sold in a pharmacy will, in theory, be enough to kill many thousands of insects. However, in practice, fighting cockroaches with boric acid requires much more poison, since the bulk of the drug is wasted, and the insects never encounter it.

This is interesting

Today, due to the frequent and widespread use of boric acid, cases are increasingly becoming known when it does not help. This is primarily due to improper use of the substance (insects do not develop resistance to it, so with the right approach they are always poisoned successfully). However, in such cases, it makes sense to use more modern and easy-to-use products against pests.

“And when we moved into the dorm, we scattered literally kilograms of this boron powder under the beds. It doesn’t work against Russian cockroaches, only powerful German drugs are needed...”

Oleg, Tyumen

Rules of application

In order for cockroaches and boric acid to occur in an apartment, it is necessary either to attract pests to it, or to place the poison where insects are constantly moving.

In the very simple case It is enough to scatter the substance in thin paths around sinks, toilets and bathtubs. It is from these reservoirs that cockroaches constantly drink water, and having gone “to a watering hole” through scatterings of poison, they will most likely become infected.

On a note

Sometimes it will be effective to place a saucer with a solution of the product near the sink. If you wipe the sink itself dry before poisoning the cockroaches with boric acid, depriving the insects of another source of water, you can force them to drink the poison - the cockroaches are in great need of regular drinking.

In any case, tracks of the drug should be scattered where cockroaches are especially common. Even before you fight cockroaches with boric acid, you can visit your kitchen and bathroom a couple of times at night and check where the mustaches scatter when the light is turned on - these are the entry points to their shelters, near which the poison should be placed.

Feedback on the use of boric acid:

“When I saw cockroaches in the apartment, I almost died of horror. In general, I can’t stand the look of them. I immediately went to the pharmacy, bought boron powder, as advised on the forum, scattered it around the sink and toilet, and did not flush it for several days. After that I didn’t see them, even though there weren’t many of them at all.”

Anna, Yaroslavl

Already such measures should give results: the main part of the cockroaches should die out, others, not poisoned, will simply leave the apartment. But if the premises are too heavily infested, the fight against cockroaches in the apartment using boric acid should also be carried out using special poisoned baits.

There are a lot of recipes for baits with boron powder, and you can come up with them yourself. The simplest and most famous of them are:

• 40-50 grams of powder are added to one raw egg yolk and everything is thoroughly mixed until a thick, mushy mass is obtained.
• Boric acid is mixed in equal proportions with powdered sugar and flour, and then kneaded with water to form a dough.
• 200 grams of boric acid are mixed with 60 grams. powdered sugar, 60 grams of starch and 20-30 grams of vanilla sugar, add enough water to make a thick and sticky mass.
• One potato is boiled in its jacket and peeled. The egg is boiled and the shell is removed. Potatoes and eggs are ground into puree, to which 1 tablespoon of boric acid is added.

From the resulting mixtures, small balls or cakes are rolled, which are laid out in those places where it is easiest for cockroaches to find them. At the same time, you must carefully ensure that, in addition to such delicacies, there is no other food for cockroaches in the room: all products must be hidden in the refrigerator, sealed in jars or plastic bags, wipe the crumbs off the table, and take out the trash at night.

It is advisable to carry out a thorough cleaning and wash the floors and walls behind and under the bedside tables and kitchen furniture before poisoning the cockroaches with boric acid.

The same is true when preparing poisoned drinking bowls: if cockroaches have a choice - to drink from a new drinking bowl or a familiar one flower pot or a toilet - they will prefer the option they are familiar with. So cleanliness is the key to success.

Destruction of cockroaches with boric acid never gives a 100% result: insects will definitely remain in the room, finding other sources of food and water, or skillfully avoiding poisoned paths. However, if there are very few pests in the apartment, and in general the apartment is clean and tidy, it makes sense to resort to this particular remedy.

In dirty old apartments, infested with cockroaches and surrounded by equally infested rooms, boric acid will, at best, help slightly reduce the number of insects. Therefore, before using boric acid, you should clean up the room.

Boric acid in the apartment: dangerous or not?

For all its toxicity to cockroaches, boric acid is of little danger to people and other warm-blooded inhabitants of the apartment - mammals and birds. At one time, pure boric acid was even used to treat wounds as an antiseptic, but doctors found that when used in this way it often leads to allergies. Therefore, today this substance is being replaced with more effective and safe substances.

“It’s so funny for me to listen to how mothers are afraid to buy boric acid for cockroaches. Like, poisonous. When we were kids, we used it to smear it on our scratches instead of green paint, and no one had any problems. Poison and don’t be afraid, nothing will happen to the children.”

Marina Vitalievna, Ust-Kamenogorsk

In any case, this weak acid will not cause poisoning in a child or four-legged friend who accidentally finds a cockroach ball or scattered powder. Therefore, you can safely use it when getting rid of cockroaches.

This is interesting

Borax is as low-toxic as boric acid. Both of these substances are registered as food additives E284. This additive is prohibited for use on the territory of the Russian Federation, but if accidentally used it will not cause harm to the body.

Where to buy and how much does boric acid cost?

Boric acid in the form of a powder or solution is sold in almost all pharmacies, including on the Internet. The price of a 10-gram bag is approximately 50 rubles, and to prepare poison, which is enough to be placed throughout the entire apartment, about 250-500 rubles will be enough.

It makes sense, when starting the fight against cockroaches, to buy several packages at once in order to prepare a sufficient amount of bait.

In general, compared to the currently popular gels and aerosols, boric acid, of course, is not a very effective remedy. Its action is extended over time and very rarely only with its help it is possible to get rid of all the cockroaches in the apartment. But its availability, safety and low cost make it one of the most widely used remedies for cockroaches in everyday life.

If you want to use something much more effective, pay attention to the modern drug for cockroaches “Lambda Zone”. This insecticide is practically odorless, safe to use and in practice is effective even when cockroaches are resistant to other insecticides.

There are many remedies against cockroaches, and folk ones are very popular. One of them is boric acid. Is it really that effective? And how to use it to get rid of such pests?

What is boric acid?

Boric acid is a weak acid that appears as small, white, odorless crystals. This product has antiseptic activity and is used for disinfection. But our grandparents began to use it in pest control, so this product cannot be called new and unusual.

What boric acid should I use?

The product is available in the form of crystalline powder and solution. Both of these forms are effective, so you can choose either one. You can also find boric alcohol, but it is not as effective. The fact is that its smell will repel cockroaches, and the active substance will ultimately not achieve its goal.

Where can I buy?

You can purchase the product at any pharmacy; it is available without a prescription and has a more than affordable price.

How does boric acid work?

Will boric acid really help get rid of cockroaches? Yes, because it can have an impact in several directions:

Is acid dangerous for people?

Boric acid is really effective against cockroaches, this is confirmed by reviews. But isn't it dangerous for people? No, if you do not inhale it or eat it, then it is not capable of causing any harm at all. Upon contact with skin, it may cause a slight and barely noticeable tingling sensation. But nothing bad will definitely happen.

How to use?

How to poison cockroaches? There are several different ways:

The most common insects that have inhabited human homes since ancient times are cockroaches. In addition to hostility and disgust, they can cause dangerous diseases. This is a good reason to wage a serious war with such neighbors. Along with the funds industrial production there is a cost-effective, simple and effective method, based on the use of boric acid. Let's find out more about recipes based on this substance.

Why you can use boric acid as a means to bait cockroaches

This acid belongs to the category weak acids, does not enter into chemical reactions with other substances, dissolves in water, has no taste or smell. It is sold in pharmacies without a prescription and can be presented in the form of:

• white powder consisting of small crystals;
• alcohol solution;
• ointments.

Boric acid is an excellent antiseptic and an excellent remedy for cockroaches

Will alcohol or ointment help get rid of cockroaches?

The effectiveness of boric alcohol is significantly lower than acids due to the presence of a specific odor that is repulsive to insects. Cockroaches simply do not eat baits made on its basis, so it does not help kill them. You should not use ointment to bait cockroaches: it contains a small amount of active substance (usually 5%) and will not have any effect. Most The best way destroy the Prussians - use the product in powder form.

Boric alcohol is not used to control insects

How does poison affect insects and humans: consequences of poisoning

Toxic acid enters the body of cockroaches mainly through the digestive tract. Just 2–3 mg of this substance causes paralysis in insects, leading to death. The product containing this acid must be prepared in such a way that the insect swallows it. In this case, you can do without edible traps. By scattering the powder in places where cockroaches are most often found, it is easy to achieve the desired result. Running on it, insects will inevitably get their paws dirty in it. The moment they are cleansed by their jaws, they will be poisoned.

They often write on the Internet that the powder is not at all dangerous to people and there is no need to be afraid of using it. It's a delusion. Of course, it all depends on how much acid has entered the body, but it is a fact that baits will be poisonous to humans as well.

Important! You cannot sprinkle the powder if there are children and pets in the apartment. This chemical is absorbed through the mucous membranes and skin and causes serious poisoning, including death. Therefore, baits must be placed only in secluded places.

Boric acid affects the peripheral nervous system of insects, causing death by asphyxiation

The effect of this acid on cockroaches has a long-term effect. When they come into contact with the powder, they carry it on their body and paws to places that are difficult to reach for treatment, thus infecting their relatives. The insect dies a few hours after taking the poison. During this time, it manages to poison both a large number of brothers and the young generation that has just hatched from the eggs (the acid does not affect the eggs themselves). During long-term use of this substance, cockroaches experience impaired reproductive functions, which can significantly reduce their population.
