Of all folk remedies for cockroaches boric acid is probably more well known. There are so many recipes of poisonous mixtures with it that it is fit to call pests true gourmets.
Boric acid is applicable practically in any rooms and situations. However, with all its versatility, this powder has its own characteristics, positive and negative. Therefore know how poison cockroaches boric acid, it is necessary before deciding whether to use it: in some cases it may be better to use other methods.
Boric acid under normal conditions is a white grain, like flakes. It has no smell and taste, melts at 170 ° С, at the same time gradually losing water and changing 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 the cure for cockroaches with boric acid or with borax will work equally well.
In nature, the reserves of pure boric acid are very limited. It is part of the mineral sassoline, which is found in small quantities in the Mediterranean and the Middle East. The dissolved substance is present in the composition of many mineral waters.
The so-called "boric powder" is a well-known antiseptic, and therefore is sold in pharmacies both in powder form and in dissolved water or alcohol form. Its solution in 70% ethyl alcohol is called boric alcohol.
On a note
Boric alcohol from cockroaches is significantly less effective than other forms of boric acid. This is due to the fact that Prusak is deterred by the smell of alcohol itself, and therefore they cannot poison themselves with acid. At the same time, boric powder from cockroaches is almost imperceptible to them, and the principle of the drug action is based on this.
The effectiveness of boric acid against cockroaches
For cockroaches, like for most other insects, boric acid is a strong poison. The effect of boric acid on cockroaches is that, getting into the digestive tract of an insect,it then penetrates through the blood into the nervous system and causes severe irritation of the peripheral nerves of the insect. When the lethal dose is exceeded, the pest begins paralysis and dies from suffocation.
Accordingly, in order for boric acid to be effective against cockroaches, it is necessary for Prusac to swallow it, and preferably in large quantities by the standards of an insect. Therefore, any remedy for cockroaches with boric acid is used so as to make the insects eat it., and questions like “How to kill cockroaches with boric acid?” are incorrect in principle - these pests do not wrinkle with powder, but poison themselves, so to speak, with pleasure.
It is not necessary to cook boron balls from cockroaches with the addition of eggs, flour, vanilla or other components, enticing them with smell and taste. In most cases, it will be sufficient to scatter the substance in places where pests often move around the baseboards, around the base of the bedside tables, under the sink. After the pest runs over the powder, the particles will remain on its paws. Then, at the shelter, the insect will begin to clean the paws with its jaws and unwittingly swallow the powder itself. With all the outgoing consequences.
A solution of boric acid from cockroaches is also quite effective if introduced into the composition of edible baits.
For the poisoning of one pest, 2-3 mg of an agent is sufficient. Consequently, a 10 gram bag sold in a pharmacy, in theory, would be enough to kill many thousands of insects. However, in practice, the control of boric acid cockroaches requires significantly greater costs of poison, since the main part of the preparation is consumed "idle", and insects with it never occur.
It is interesting
In addition to Prusak, this tool effectively destroys domestic ants, working on the same principle. But against domestic bugs, boric powder is absolutely useless: these parasites can eat only by sucking blood with the help of their proboscis. Accordingly, even with a strong desire, bugs will not be able to eat such a poison.
Today, due to the frequent and widespread use of boric acid, it is increasingly becoming known cases when it does not help. This is primarily due to improper use of the substance (insects do not develop resistance to it, therefore, with the right approach, they are always successfully etched).However, in such cases it makes sense to use more modern and easy-to-use products against pests.
“And when we entered the hostel, we literally poured this boric powder under the beds in kilograms. It does not work against Russian cockroaches, only powerful German preparations are needed ... ”
Rules of application
In order for the cockroaches and boric acid to meet in the apartment, it is necessary either to attract pests to it, or to place the poison where the insects are constantly moving.
In the simplest case, it is enough to scatter the substance in thin paths around the sinks, toilet bowl and bath. It is from these reservoirs that cockroaches constantly drink water, and when they “go to the water” through the placers of poison, they are likely to be infected.
On a note
Sometimes it will be effective to put a saucer with a solution around the sink. If the shell itself, before poisoning cockroaches with boric acid, is wiped dry, depriving the insects of another source of water, you can make them drink poison - the cockroaches are in need of regular drinking.
In any case, the paths of the drug should be scattered where cockroaches occur most frequently.Even before fighting with cockroaches with boric acid, you can visit your kitchen and bathroom a couple of times at night and check where the baleen run away when the lights are turned on - these are the entry points to their shelters, near which poison should be placed.
Feedback on the use of boric acid:
“When I saw cockroaches in an apartment, I almost died of horror. In general, they can not stand to look. I went to the pharmacy right away, bought boric powder, as advised at the forum, scattered around the sink and the toilet bowl, did not wash it off for several days. After that, I did not see them, even though there were few of them at all. ”
Already such measures should give the result: the main part of the cockroaches should die out, others, unfinished, just leave the apartment. But if the room is infected too much, the fight against cockroaches in the apartment with the help of boric acid should also be carried out with the help of special poison baits.
There are a lot of recipes for boron powder baits, and you can invent them yourself. The simplest and most famous of them are:
- In one raw egg yolk, 40-50 grams of powder is added and everything is thoroughly mixed until a thick pasty mass is obtained.
- Boric acid disperses in equal proportions with powdered sugar and flour, after which it is kneaded in water to form a dough.
- 200 grams of boric acid mixed with 60 grams. powdered sugar, 60 grams of starch and 20-30 grams of vanilla sugar, they add enough water to form a thick and sticky mass.
- One potato is boiled and cleaned. Boiled egg, shells are removed from it. Potatoes and eggs are mashed into mashed potatoes, in which 1 tablespoon of boric acid is added.
From the resulting mixtures roll small balls or pellets, which are displayed in those places where the cockroaches are the easiest to find them. It should be carefully monitored so that in addition to such snacks, there was no longer any other food for cockroaches in the room: all products should be hidden in the refrigerator, covered in jars or plastic bags, crumbs should be wiped off the table and taken out at night.
It is advisable before poisoning cockroaches with boric acid, to carry out a thorough cleaning and to clean the floors and walls behind and under the bedside tables and kitchen furniture.
The same is true when cooking poisoneddrinking bowls: if cockroaches have a choice - to drink from a new drinker or a flower pot or a toilet bowl they are accustomed to - they will prefer the usual option. So cleanliness is the key to success.
The extermination of cockroaches with boric acid never gives a 100% result: insects will always remain in the room, finding other sources of food and water, or skilfully bypassing the poisoned paths. However, if there are very few pests in the apartment, and on the whole the apartment is clean and well maintained, it makes sense to resort to this particular tool.
In filthy old flats abounding in cockroaches and surrounded by equally contaminated premises, boric acid will at best help to slightly reduce the number of insects. Therefore, before bring cockroaches boric acid should clean up the room.
Boric acid in the apartment: dangerous or not?
For all its toxicity to cockroaches, boric acid is low-hazardous to humans 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 with this use, it often leads to allergies.Therefore, today this substance is replaced by more effective and safe substances.
“It’s ridiculous for me to hear how mommies are afraid of buying boric acid from cockroaches. Like, poisonous. In childhood we used scratches on them instead of greens, and no one came up with anything. Poison and do not be afraid, nothing will happen to children. "
Marina Vitalevna, Ust-Kamenogorsk
In any case, this weak acid will not cause poisoning in a child or a four-legged friend who accidentally finds a cockroach ball or loose powder. Therefore, it can be safely used, getting rid of cockroaches.
It is interesting
Borax is as low toxic as boric acid. Both of these substances are registered as a food additive E284. On the territory of the Russian Federation, this additive is prohibited to use, but with an accidental use of harm to the body does not cause.
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 bag of 10 grams is about 50 rubles, and about 250-500 rubles will be enough to prepare a poison, which is enough to accommodate throughout the apartment.
It makes sense, starting the fight against cockroaches, to buy several packages at once in order to prepare a sufficient number of baits.
In general, compared with the currently popular gels and aerosols, boric acid, of course, is not very effective. Its action is stretched in time and very rarely only with its help it turns out to get rid of all the cockroaches in the apartment. But the availability, safety and low cost makes it one of the most widely used tools from cockroaches in everyday life.
If you want to use something much more effective - pay attention to the modern drug from the cockroaches "Lambda Zone". This insecticidal agent is practically odorless, safe to use and in practice it is effective even when cockroaches are resistant to other insecticides.
Good luck to you in the fight against insects!
Will boric acid help to get rid of cockroaches
5 rules for choosing the service for the destruction of cockroaches
Thank you, informative. I have no cockroaches, but my brother just had horror, found your website, dropped the link for him.
Everything is painted just perfect 😉
Thanks for the info, everything is written in such detail. We had no cockroaches for seven years, and then some kind of invasion. I used the tips, now I wait for the results. Thank!
My wife and I live in a hostel. Cockroaches - darkness. Today poured boric powder. The main place of residence is cockroaches behind the refrigerator. Let's see what will happen. Keep your fingers crossed, well, very much they are tired of us.
Waiting for the result
Just powder, scattered tracks, ineffective. But the balls of yolk and boric acid powder will help a lot. Even if you instead of balls turned zizhechka, then it can be spread on cardboard and spread out. They did this in a hostel - there were fewer cockroaches (throughout the hostel, and not just in our room).
In the fire station in two floors with parquet floors sprinkled with boric acid in the kitchen and in the dormitory, on baseboards behind the refrigerator. And they did not clean the floors for a month. And they disappeared once and for all.
Thanks for the advice, I will try to take advantage!
I take advantage of your advice, waiting for the result. Did boric acid with egg 30 gr. on 1 yolk.
Tell me, wait for the result?
Where did you buy boric acid?
In the pharmacy.
Boric acid is better to buy in firms trading chemical reagents. In Samara, we have Reakhim, boric acid costs around 100 rubles per kg.
Thank you all for the great advice 😉
And from black cockroaches boric acid will help get rid of?
We had black cockroaches, climbed out of the sewer. Then ordinary street frogs appeared (we lived in the village), and the cockroaches disappeared themselves, and the frogs, too.
Thank you very much, we will test)
It is best to mix the boiled yolk with boric alcohol, slowly go away, and they will not exist until they climb in the basements. Just sometimes the bait needs to be updated.
Thanks for the recipe. I hope everything will be fine with us.
Only eggs should be taken from the village, they are tastier)) For the seed ...
And if boric acid (powder) is diluted with water and sprayed the places where they usually live, will it help? And in what proportion to do it ???
Maybe, who knows and will tell us ... We have some insects, they are not visible, but there are traces of their vital activity everywhere (terrible yellow dots), all things, furniture, etc. linger on them. I just do what I wash and wash. SES did not help. This is horror, I blocked the whole Internet, I can not find anything, there is a problem, but I don’t know who creates it and how to deal with it ((
Perhaps it is a mole.
Boric acid helps, but cockroaches do not disappear for good, then after 2-3 years they appear again.
The best cure for cockroaches!
And in our private house cockroaches appeared. Probably, my aunt brought, because she has had a fight with them in the apartment for decades. They, it seems, are few, but I burned 15 pieces of January for January, both large and fatty, and a couple of small ones.
So, on February 2, I bought boric in the evening, mixed 30 g with boiled egg yolk, and some water for consistency. Laid out wherever she saw and did not see cockroaches.
Results for 3 days: February 3 - not a single reptile came to my eyes. February 4 - one “greeted” my sneaker, saw it in a crushed form - there was some white mess inside.February 5 - in the morning one lay shamelessly on his back, moving his paws, in the evening he was caught by the second, but he so cheerfully ran about his business - the insides were black-and-white-gray.
I will unsubscribe in a couple of weeks about the result. So far, only boric acid is trying, for the purity of the experiment and to identify the effectiveness of the method.
Waiting for your result. I like a cockroach in the apartment will fall - immediately processed the gels. What just did not try, briefly. Spray special treated, half a year was not visible. Appeared again. Has smeared with chalk, so them became even more. Yesterday, that's everywhere for the plinth, for the cabinets poured boric acid. Hope on her.
One cockroach was sent on February 15 and forgot about them. I literally just killed one more petty and remembered my feedback here. Apparently, these balls need to be updated more often than once a month: /
The bottom line: the result is there, but MUST BE SUPPORTED.
For the last two I can not vouch that appeared in the house, perhaps, as a relative brought ...
Tell me, please, can I just mix potatoes with boric acid, without eggs?
I have a very large number of these friends, which I have not tried! And with all sorts of newfangled preparations she sprayed the apartment, and she also smeared various kinds of glue, and even the Regent, who was poisoned by the Colorado potato beetle, did not help. Here, I read tips about boric acid, dribble balls, I'm waiting! Tell me, is it at least effective?
I'll try. Thank.
He lived in a hostel for 6 years. This is the only effective remedy for cockroaches, it is also very cheap. They poisoned the whole block, it was enough for 6-7 balls per room + kitchen and toilet. They disappear for a long time.
Tell me please! Approximately how they disappear, subject to constant maintenance of cleanliness in the room? He also settled down in a hostel and got acquainted with such bad guys ((Like, he cleaned the room completely, but they don’t want to leave.
Tell me please. Today I spread two small yolks with one packet of boric acid and spread it all over the apartment. I understand that this bag will not be enough for them? Can they divorce even more? And how to be now? ((
I also used boric acid today, processed the whole house, even prepared them porridge. Now I am waiting for the result ...
And I messed up, I used white instead of yolk, it doesn't work anymore, yes, people?
Dana, you need a yolk!
And I am a raw egg with bread mixed up to a thick mixture and 70 grams of boric acid sprinkled. I rolled the balls and laid them out in their habitats, waiting for the result.
Bought a cottage with cockroaches. There were many. A lot is to go out to the kitchen at night, turn on the light and see 20-30 individuals. Began to poison boric acid with yolk. Mixed 4 yolks and 3 pharmaceutical bags, spread out balls everywhere. I didn’t notice the effect right away, after two weeks I didn’t see it at 20-30, but at a maximum of 10, after a week - there were a maximum of a couple, after two more - there are none. In general, no one was alive again, but there were just crowds.
Knowledgeable people advise to update this bait every couple of months and constantly keep half a year.
Well, is the result of boric acid?
And today I poured boric acid on fried potatoes, they gathered on it. This method will help ?!
A bag of 10 grams of acid in the pharmacy, we have 47 rubles. In the shop "Seeds" - 18 rubles. In the chemical retailers, a whole kilogram costs only 85 rubles.
Also today spread everywhere, even behind the toilet and in the bathroom. They got strong, I open kitchen cabinets, and they fall on my head! I tried 1000 means, at night everything is dry, not a crumb! And they such lean, run!
And we rented an apartment, of course, during the day we looked, there were 1-5 cockroaches. The owner, I see, scattered the poison, he said, before this was not, the former tenants did not poison. Came in the evening with her husband to send a marafet. They turned on the light and ... They ran everywhere: in the kitchen, in the room, and in the bathroom. There are 20 pieces. I'm 8 months pregnant, I urgently need an apartment, there’s no other option to look for another. In general, I went, I bought a gel, I was given some kind of thing to dissolve. In general, I sprinkled this thing, smeared it with a gel, still sprinkled with dichlorvos, ran away, not breathing. Now I'll go buy some boric acid and roll the balls. See the result. Then I will write.
Incidentally, I lived in a hostel, it seemed to me that I had not seen so many cockroaches. And there every month in the morning before work, she passed the gel over the baseboards, behind the fridge, and squirted with a raid and left, by the evening everything would erode and cockroaches are smaller, 1-2 pieces
I will poison, I make 5 types. Maybe something will help.
Cockroaches this way is easy to bring in a private house. But from the apartment they are not derived from me. I live on the 1st floor. In the basement, fleas are constantly being poisoned with some kind of gas, and it can be seen that the Prussians also live there. So, they come to us and run after the persecution. 4 years can not withdraw ((
From fleas there is a very effective and very safe remedy - alcohol tincture of wormwood. Internet to help you. Only I did not measure with spoons - poured half a bottle. And that's it! Never seen again.
Where to pour?
We live on the 5th floor of the five-story building, these reptiles climb to us from ventilation. Nothing takes them - gel, dichlorvos, sticky gel ... Let's try acid. Zadolbali.
It is necessary to glue the small plastic mesh. Instead of hoods, use a vent.
Our neighbor started repairing from above and from that moment cockroaches went. Already 2-3 months of suffering. The ventilation was closed with a net, but we have pipes and counters behind a wooden door and in no way tightly close ((I try boric acid today ...
Very interesting, thank you all.Also, for ten years, there was no cockroach, but after the heat of 37 degrees this summer, they would break! Is there any connection?
Also after the heat appeared, before there was.
Anyone who thinks to use boric acid against cockroaches or not? YES! It so happened that the cockroaches here bred at home, and not a couple, and not 20-30 pieces, as they write here, but a whole army! I used all sorts of gels, chalk, spray, the result was temporary, they disappeared for a while, and when they appeared, these funds did not work against them. One friend advised boric acid with boiled potatoes to use. And to my great surprise, cockroaches died out well, just hundreds. I have two kids, so I put poison at night, in the morning I went out to the kitchen, and on the floor lay the whole camp! HOWEVER you need to maintain. The effect is not seen immediately, somewhere on the 5th day. I fought with them for 2 weeks, half a year passed, and again a couple appeared. I will continue to fight.
Guys, we have +20 in Tashkent in winter, so cockroaches tortured us. I spend generals every season, from the ceiling to the floor, every centimeter. After it, day 2 cockroaches are not visible, and then all over again.And only boric acid with an egg helps for a long time, but it is necessary to update. Good luck to all.
Try mixing 50 grams of boric acid with 1 tablespoon of chicken seasoning. Cockroaches are very fond of spices, and with boric acid this will be their last meal.
In childhood, they lived in a hostel. Also their darkness was, then they moved, they also crawled from their neighbors. So, the mother brought them just boric acid with an egg. It helped. Now I moved to a new apartment 2 years ago. Half a year ago, creeping midges divorced, destroyed by dust in the summer. Now a new attack, cockroaches rod. Negro neighbors. Pigs, everything creeps from them. I will fight a proven method. Gels and traps do not help. Today poured, I will follow. In the afternoon I will roll more balls. Hate them. Already shakes when I see. Nasty creatures.
I called the chemist, processed for 2 thousand - and no result. I bought a Pest repeller, also for 2 thousand - the third month of work and no sense, they don't care, they run. So who wants to buy this garbage: think, money down the drain. Here too I will try in the old manner boric. At least cheap.
Hello! Followed the advice and bought boric acid. Has made balls, scattered in habitats. But here the tool does not help ((In the kitchen they became even more than usual. Previously, they were afraid to climb out into the light, but now they are already running around and are not afraid. What should I do now if the tool does not help?
Daria, they really get bigger first, we were scared ourselves. It seemed to me that from all over the house came to visit us)) Read my experience below.
Is a boric acid alcohol solution suitable?
Hello! I live in a Stalin-era building, a communal apartment. As far as I can remember, there were so many cockroaches that goosebumps. If you go into the kitchen at night, the whole tower was a carpet of cockroaches, and there were a lot of them in the rooms.
I was advised to boric acid with an egg. It was laid out on the perimeter of all the rooms, half a meter, half a teaspoonful (in places where there were especially many of them, more was laid). Laid out even on the cabinets and bedside tables. After 3 days, 1.5 buckets of cockroaches were carried out. Repeated after 2-3 weeks, I do not remember exactly.
From 1999 to 2016 I DIDN'T SEE ANY ONE TRACQUAN!
I was told that they would forget the way to the apartment for 15 years)) It is very important to repeat! I hope my advice will help.
Boric acid is the only drug to which the baleen has not yet adapted. The remaining poisons (any) in cockroaches can develop resistance (if you regularly use the same drug).
And we have a problem. About 10 years ago we brought out all the horde of boric acid. Now one of the neighbors again threw up. Darkness is darkness. I did the same with balls with boric, yolk and potatoes. And these bastards do not eat them. Just ignore ((
Raw or boiled eggs?
Here they write that for ten years they brought cockroaches. So they, like, were not anywhere! They completely disappeared in 10 years approximately, from 2000 until recently. Everyone wondered where they went, what type of radiation) Really? Or maybe it seemed to me that they were somewhere. Just wondering. I was already glad that it was forever they disappeared from the face of the earth. But here again appeared.
We also disappeared cockroaches about 12 years ago, and about 7 years ago they began to slowly appear, but then I installed wi fi and they disappeared, maybe not because of that, but I heard several similar stories. 5 years ago appeared again. I tried everything, but boric acid helped, and then sometimes I used purchased traps and everything was fine. But about 3 months ago, just a nightmare that started, just darkness of cockroaches, and at the same time - both small, and big, and thin, and thick. I will use boric acid again. I still helped dust powder, but the stench is impossible, and the poison is still, you can like it yourself.
And I tried to use such balls from small red ants. They gathered in a crowd at one of the balls, I just touched them - they scattered. They really liked the yolk and butter, but the boric acid remained untouched)) Maybe I got this, or ants with armor ...
Tell me, please, and technical boric acid is suitable from cockroaches?
