Boric acid is a common product used to control harmful insects. Cockroaches, which have been annoying humans since ancient times, are carriers of foodborne infections. There are numerous drugs on sale, but people often turn to folk remedies, among which boric acid is very popular.

Drug safety

Boric acid does not irritate the skin of the hands and does not leave chemical burns on them. This product is used to bait cockroaches, even if there are children or pets in the house. The acid poses little danger and was previously used as a disinfectant, but has since been replaced by other means. Basic caution must be exercised when working with the chemical.

Children under 3 years of age are prohibited from coming into contact with boric acid. Contact with the product should be avoided by women expecting a child, nursing mothers, people predisposed to allergic skin diseases, and those with kidney disease.

If animals get to the bait, nothing bad will happen to them, but it is better to exclude such a situation and remove the product away from children and animals. The powder may cause an allergic reaction. If acid enters the body, the following symptoms may appear:

• headache;
• nausea;
• vomit

Acid powder is less dangerous than other chemicals for baiting pests, and therefore is often used for urgent treatment of premises. What are the properties of the substance?

Precautionary measures

In general, the substance does not fully correspond to the universal concept of acid. Under the influence of boric acid, there are no chemical burns on the body. However, certain precautions must be taken when using the product.

The use of such poison is allowed even when children and pets are present in the room. Boric acid is not as dangerous when compared with Karbofos and Executioner, and for some time it was used as an antiseptic. Although in some cases, when using the substance, an allergy appears.

The drug, in comparison with specialized insecticidal products for protection against cockroaches, practically does not harm children, however, children under 3 years of age should not come into contact with it. If a cat or dog eats “bait” with boron powder, death does not occur, however, it is recommended to avoid such a situation.

Contact with the drug should be avoided during pregnancy and lactation, as well as people suffering from kidney failure, skin ailments of inflammatory etiology in the acute stage. If the powder gets inside, the development of vomiting, headaches, and rashes is observed. Do not forget that when choosing a drug to exterminate parasites in a residential area, you first need to think about the safety of the people living in it. Proven, harmless, fragrance-free insecticides are Global and Forsyth gel preparations.

Properties of boric acid, effect of the drug on insects

Boric acid is a crystalline powder, poorly soluble in water, odorless. The white grains are similar to scales. The product can melt and change its composition at a temperature of 170 degrees. The substance is found in the mineral sassolin, found in the Middle East and Mediterranean. More information about the substance is on Wikipedia.

In the pharmacy, the product is sold in alcoholic form, diluted with water, or in powder form. A solution of acid in 70% ethyl alcohol is called boric alcohol. It has a pungent odor. Alcohol is not the best option for pest control. The specific smell scares insects, so they do not touch the bait. The powder is completely invisible to cockroaches. The method of dealing with them is based on this. Pests carry it to their shelter on their paws or eat it with food.

Boric acid is a strong poison for cockroaches. Pests are unpretentious in food, and this factor can be used when baiting Prussians. Once in the insect’s digestive tract, the acid affects the pest’s nervous system through the blood, causing severe irritation of the nerve endings. If the dose exceeds the permissible level, paralysis occurs in the pests and they die from suffocation.

Cockroaches that come into contact with the powder can become poisoned. Particles of the product will stick to the paws of cockroaches after the pests run through the powder. Returning to the shelter, the insects will begin to clean their legs and swallow the powder. To poison 1 insect, 2-3 mg of powder is enough. A sachet sold in pharmacies, weighing 10 g, is enough to kill 1000 parasites.

As practice shows , the toxic substance is consumed in larger quantities. Part of the product goes unnoticed by the cockroaches and is wasted. For boric acid to be effective, the insects must ingest as much of the powder as possible. Therefore, it is necessary to prepare attractive baits for them.

Effectiveness of anti-cockroach product

Cockroaches, like many other parasites, perceive boron powder as a strong poison. The substance enters the insect’s digestive organs and subsequently affects the peripheral nervous system. If the lethal dosage is exceeded, the pest develops paralysis and dies from asphyxia.

As a result, for a cockroach to die, it must eat the poison, and the dose must be significant in relation to the weight of the pest. In this regard, any drug with powdered boric acid against cockroaches is prepared so that the insects eat it.

How to kill cockroaches with boric acid? It is not always necessary to mix eggs, flour, vanillin or other components with boric acid in order to attract cockroaches with the aroma and taste of the poison. Sometimes you can simply sprinkle the substance on areas of maximum concentration of parasites - along baseboards, along the edges of furniture, near sewer drains. Running along paths, the pest picks up poison on chitin. When cleaning the shell, involuntary ingestion of the substance will occur, which will ultimately lead to the death of the insect. Boron powder in liquid form is also quite effective in exterminating parasites when used as a component of edible “bait.”

To poison one insect, you only need 2–3 mg of the substance. As a result, a package of 10 grams of the substance helps to destroy a significant number of pests. Although practice has proven that to exterminate parasites, a significantly larger volume of poisonous powder will be needed, since cockroaches do not even encounter most of the product on their way.

In addition to cockroaches, the substance helps in the fight against house ants. But such a remedy is useless for eliminating house bugs, because these insects feed only by sucking blood through their proboscis. So the poison does not affect bedbugs.

Today, boric acid is used frequently and everywhere, so people often complain about the ineffectiveness of the substance. This is due to improper use of the drug; the pest does not form a habit of the substance. However, in such cases, you need to think about exterminating pests using other, more effective drugs.

Baits for cockroaches, recipes, methods of using products

The powder should be poured in insect habitats:

• cracks along the baseboards;
• area under furniture;
• places near the bathroom, under the sink.

In addition to the kitchen, cockroaches are attracted to the bathroom. Insects cannot exist without water, this place is dark, no one causes disturbance. The scattered product sticks to the paws of pests and, entering the body of insects, leads to death. Pour the powder in small piles to create the impression that granulated sugar or flour has been spilled, otherwise the insects will bypass the bait. The disadvantage of this product is that the acid is ineffective in killing insect eggs.

When fighting cockroaches, the following methods are used:

• use of powder without impurities;
• production of baits;
• use of solutions.

Recipe for boric acid with egg against cockroaches

There are various recipes for baiting insects using boric acid. It is not difficult to make a poisonous insecticide; we list the basic recipes.

Recipe 1. Take a raw egg and separate the yolk, combine with 50 g of acid. Mix the composition until a homogeneous mass is obtained. Form into balls and place in cockroach habitats.

Recipe 2. Boil 1 potato and 1 egg. Mash the potatoes, add 40g of powder, egg yolk and sunflower oil.

Recipe 3. Take raw yolk, 2 tbsp. spoons of granulated sugar, 40 g of powder. Then pour in water or add flour to form a viscous mass.

Recipe 4. For this recipe you need to take 200 g of acid, 60 g of starch and the same amount of powdered sugar, a packet of vanillin. Mix everything and dilute with water until a thick mass is obtained.

Recipe 5. Mix 1 boiled potato with 4 packets of acid, add 1 boiled egg yolk and a little kefir.8

Balls are prepared from the resulting mixtures and placed in pest habitats. The yolk of the egg eliminates the smell of acid and stimulates the appetite of insects. Humans do not smell, but cockroaches have a fairly developed sense of smell.

Ask a Question

The number of components can be changed depending on the volume of the area being cleaned. The prepared composition according to 1 recipe is enough to exterminate cockroaches in 1 room. If you need to prepare a product to get rid of insects throughout the house, increase the amount of ingredients. The death of cockroaches occurs a few days after they eat the bait. Usually it is 2-3 days.

To kill as many cockroaches as possible, you will need more chemicals. In order for the insects to get hungry and decide to eat the balls, it is necessary to remove all food and crumbs from the kitchen and take out the trash. In addition to dry bait, liquid poison is prepared for pests.

The best recipes with boric acid

During the period of struggle against harmful insects, man came up with a large number of techniques and baits.

Balloons

A well-known method is balls from cockroaches and prussians with boric acid and egg or other products.

They are small in size, easy to form, and the ball lasts for a long time without falling apart. It is convenient for cockroaches not only to consume such bait, but also to move it to their colony.

An important point is the aroma so that the treat does not go unnoticed by parasites. It is preferable to use products that will have a “delicious” smell.

Bait with egg

The eggs help bind the powdery substance together and give it a pleasant taste. To prepare the bait you will need 50 grams of acid and one yolk. Boil the egg hard and separate the yolk. The ingredients should be mashed and mixed thoroughly. Then you can form balls 5 mm in diameter from the resulting mass.

A cockroach repellent with boric acid and egg is used more often than others in pest control.

Yolk and potatoes

This recipe requires a whole egg (yolk), one potato and 250 grams of poison. Here's the step-by-step preparation. After the products are boiled, they are peeled and shelled and finely ground. Then the powder is added and a homogeneous mass, reminiscent of puree, is prepared. Be sure to mix the resulting consistency well.

At the final stage, you can sculpt balls. In this case, more poisonous bait is obtained, therefore, it is designed for a larger number of individuals.

With flour and powdered sugar

The most spoiled cockroach will not refuse such a treat. For poisoned bait you will need granulated sugar, flour, egg and acid.

Compound:

• Boric acid powder – 4 packs (40 grams);
• Egg – 1 pc.;
• Sugar – 2 tbsp. l.

How to cook:

1. Mix raw egg yolk with sugar.
2. Add acid.
3. If the mixture is too thick, add a little water. If you need to thicken it, add a little flour.
4. Form small balls and place them in the desired place.

Liquid solution of boric acid against cockroaches

In order to make a liquid poison for pests, several bags of powder are poured into a container of water. The more saturated the solution, the more effective the result. The prepared mixture is poured into small saucers or jar lids and placed in the far corners of the kitchen under the furniture. Cockroaches will try the bait in the absence of water. To do this, carry out the following actions:

• thoroughly wipe the sink;
• close the taps well;
• At night, remove all wet wipes and sponges.
• pots and vases with flowers are moved to another room, because insects are accustomed to taking water from the soil.

The product will not work if the pests taste the poison and then drink the water.

When preparing and spreading poison for cockroaches, you must wear a protective mask and gloves. Although acid poses a slight danger, it is still a chemical and should not be allowed to come into contact with the surface of the skin. Only after protective measures do they proceed to chemical treatment at home.

Room treatment

To get rid of cockroaches, you need to carefully prepare the room for the planned event. To exterminate insects, the following measures are taken:

• preparing the apartment for pest persecution;
• preparing poison for insects;
• decomposition of bait.

Before you start killing cockroaches, you need to clean the room. Pests will be able to eat the poisoned bait if there is no food or water nearby. The balls must be placed in the favorite habitats of the parasites. The poison affects the behavior of insects. Cockroaches emerge from hiding during the day. They become leisurely in their movements. The death of insects will occur in a few days.

Prevention of re-infection of the premises

When the house is cleared of pests, you should not stop at the achieved result. If insects persist in neighboring apartments, they can enter the cleaned room. Boric acid will help in carrying out preventive measures against the return of Prussians. The following conditions must be observed:

• make and place insect bait in far corners;
• maintain order in your home.

It is necessary to study the instructions for use of the drug indicated on the packaging. A large number of baits that affect insects are prepared from the powder. When there are a lot of cockroaches in a room, you should resort to store-bought preparations, and then use boron powder to prevent re-infestation of the room with insects.

Recipes for making baits

Poison for cockroaches with boric acid is prepared only with a powder product. Alcohol tincture is not used for these purposes. The simplest method of using the drug is to create a thin path near baseboards, sinks, furniture, sewerage and water supply. However, this method of use is characterized by insignificant effectiveness. In this regard, it is recommended to make poisonous “bait” with a powdery substance. How to prepare poison for cockroaches?

With added egg yolk

The most common way to exterminate cockroaches is to prepare bait from egg yolk with boron powder:

1. Hard boil one egg.
2. Grind the yolk with a fork.
3. You need to add boron powder into the resulting slurry at the rate of 20 g of the substance per 1 yolk.
4. The composition is mixed with vanillin or vanilla sugar for flavor.

Boric acid has no taste or aroma, so you can safely use it to make poison - cockroaches will not smell it.

The resulting mixture is laid out in the form of small pellets in those areas where there is an accumulation of parasites, and kept for 7 days.

With potatoes

You can make bait with potatoes in a similar way:

• you need to boil 1 medium potato and mash it;
• to make the composition viscous, add 1 raw egg;
• 40–50 g of powdered boric acid is added to the composition;
• Vanillin is used for flavor.

The drug is distributed in the form of small balls on cellophane or paper in the cockroach habitat and kept for 7 days.

Liquid bait with sugar

Poison with added sugar in liquid form is administered before bedtime, and the room should be prepared beforehand. The purpose of this technique is to deprive parasites of access to water:

• Before going to bed, turn off the water, wipe sinks, bathtubs, and taps dry;
• the dishes are dried, damp rags, sponges, washcloths, pet bowls and other liquids are removed;
• flower pots are taken to another room.

Then the poison is prepared: boric acid (50 g) is added to clean water (0.1 l). Any sugar or honey (1 tablespoon) can be added to the mixture. The poison is poured into small containers and placed in the kitchen sink, sink and bathroom. In the morning the liquid is removed.

To exterminate cockroaches in this way, you will need to create a cumulative effect for at least 10 days. At the end of the 2-week break, the treatment is carried out a second time.

With sunflower oil

Sunflower oil is added to the bait to attract cockroaches with its aroma. As a result, it is recommended to use an unrefined product made from roasted sunflower seeds.

Sunflower oil can be added to any recipe - with eggs or potatoes.

Eg:

• mix powdered boric acid (30 g) and 1 boiled yolk;
• Vegetable oil (1/2 teaspoon) is added to the mixture.

Sunflower seed oil in poisonous insect bait can also be replaced with sesame oil.

Boric acid cost

How much money will you have to spend to purchase boric acid? The purchase will not require significant funds. A bottle containing 25 ml costs 10 rubles. A package of powder costs 50 rubles. It is advisable to purchase the product in sachets. It is recommended to buy several packets of powder. This will cost 200-250 rubles.

You should not expect quick results if you are trying to urgently destroy all the cockroaches in the house. The use of the product is effective when there are few insects and the apartment is kept clean. It happens that pests get used to the powder due to frequent or improper use of the product, or cockroaches that are resistant to it appear.

Sometimes you can use store-bought drugs and then use this folk remedy. Compared to modern aerosols and gels, acid is less effective. However, the availability, safety and low cost of the drug makes boric acid a popular tool in the fight against cockroaches in the home.
