Of all the folk remedies for cockroaches, boric acid is known, perhaps, more than anyone else. There are so many recipes for poisonous mixtures with her that it is just right to call pests true gourmets.
Boric acid is applicable in almost any premises and situations. However, for all its versatility, this powder has its own characteristics, positive and negative. Therefore, it is necessary to know how to poison cockroaches with boric acid even before deciding whether to use it: in some cases it may be more appropriate to use other methods.
General properties
Boric acid, under normal conditions, is 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 borax or borax roach repellent will work equally well.
In nature, the reserves of pure boric acid are very limited. It is part of the mineral sassolina, 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 "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 for cockroaches is significantly less effective 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 will not be able to poison themselves with acid. At the same time, boric powder from cockroaches is practically invisible to them, and the principle of the drug's action is based on this.
The effectiveness of boric acid against cockroaches
For cockroaches, as well as for most other insects, boric acid is a strong poison. The effect of boric acid on cockroaches is that, getting into the insect's digestive tract, it then penetrates through the blood into the nervous system and causes severe irritation of the insect's peripheral nerves. When the lethal dose is exceeded, the pest begins paralysis and dies from suffocation.
Accordingly, in order for boric acid against cockroaches to be effective, it is necessary that the Prussian swallow it, and preferably in a large amount by the standards of an insect. Therefore, any remedy for cockroaches with boric acid is used in such a way as to force insects to eat it., and questions like “How to kill cockroaches with boric acid?” are in principle incorrect - these pests do not wash themselves with powder, but are poisoned, so to speak, themselves and with pleasure.
It is not at all 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 - near the baseboards, along the perimeter of the base of the bedside tables, under the sink. After the pest runs over the powder, the particles will remain on its paws. Then, in the shelter, the insect will begin to clean its paws with its jaws and involuntarily swallow the powder itself. With all the consequences.
A solution of boric acid from cockroaches is also quite effective if you introduce it into the composition of edible baits.
For the poisoning of one pest, 2-3 mg of the agent 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, the fight against cockroaches with boric acid requires much more poison, since the main part of the drug is spent "idle", and insects never meet with it.
It is interesting
In addition to the Prussians, this tool effectively destroys domestic ants, working on the same principle.But against domestic bugs, boron powder is absolutely useless: these parasites can only feed by sucking blood with their proboscis. Accordingly, even with a strong desire, the bugs will not be able to eat such poison.
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 the improper use of the substance (insects do not develop resistance to it, therefore, with the right approach, they are always successfully poisoned). However, in such cases, it makes sense to use more modern and easy-to-use means against pests.
Review
“And when we entered the hostel, literally kilograms of this boron powder were scattered under the beds. It does not work against Russian cockroaches, only powerful German drugs are needed ... "
Oleg, Tyumen
Application rules
In order for cockroaches and boric acid to meet in an apartment, it is necessary either to attract pests to it, or to place poison where insects constantly move.
In the simplest case, it is enough to scatter the substance in thin paths around sinks, toilets and bathrooms. It is from these reservoirs that cockroaches constantly drink water, and having gone “to the watering place” through placers of poison, they are likely to be infected.
On a note
Sometimes it will be effective to put a saucer with a solution of the product near the sink.If the sink itself is wiped dry before poisoning the cockroaches with boric acid, depriving the insects of another source of water, you can force them to drink poison - cockroaches are in great need of regular drinking.
In any case, the paths of the drug should be scattered where cockroaches are most 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 poison should be placed.
Feedback on the use of boric acid:
“When I saw cockroaches in the apartment, I almost died of horror. I generally don't look at them. I immediately went to the pharmacy, bought boron powder, as advised on the forum, scattered it around the sink and toilet bowl, and did not wash it off 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 a result: the main part of cockroaches should die out, others, not poisoned, will simply leave the apartment. But if the room is too heavily infected, the fight against cockroaches in the apartment with boric acid should also be carried out with the help of special poisoned baits.
There are a lot of recipes for baits with boron powder, and you can invent them yourself. The simplest and most famous of them are:
- 40-50 grams of powder is 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, after which it is kneaded in water to obtain a dough.
- 200 grams of boric acid are mixed with 60 gr.powdered sugar, 60 grams of starch and 20-30 grams of vanilla sugar, so much water is added to them to make a thick and sticky mass.
- One potato is boiled in their skins and peeled. The egg is boiled, the shell is removed from it. Potatoes and eggs are mashed into a puree, to which 1 tablespoon of boric acid is added.
From the resulting mixtures, small balls or cakes roll, which are laid out in those places where it is easiest for cockroaches to find them. At the same time, it is necessary to carefully monitor that, in addition to such sweets, there is no other food for cockroaches in the room: all products must be hidden in the refrigerator, closed in jars or plastic bags, wipe the crumbs from the table, and take out the garbage 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 drinkers: if cockroaches have a choice - to drink from a new drinker or their usual flower pot or toilet bowl - they will prefer the option they are used to. So cleanliness is the key to success.
The 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 bypassing poisoned paths. Nevertheless, if there are very few pests in the apartment, and in general the apartment is clean and well-groomed, it makes sense to resort to this particular remedy.
In dirty old apartments, teeming with cockroaches and surrounded by equally infested rooms, boric acid will at best help to reduce the number of insects a little. Therefore, before removing cockroaches with boric acid, you should clean up the room.
Boric acid in the apartment: is it dangerous or not?
For all its toxicity to cockroaches, boric acid is of little danger 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 when used in this way, it often leads to allergies. Therefore, today this substance is being replaced by more effective and safe substances.
Review
“It’s so funny for me to hear how moms are afraid to buy boric acid from cockroaches. Like, poisonous. In childhood, instead of green paint, they smeared scratches with it, and nothing arose from anyone. Harass and do not 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, 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 food additive E284. On the territory of the Russian Federation, this additive is prohibited for use, but if accidentally used, it will not harm 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 bag of 10 grams is approximately 50 rubles, and about 250-500 rubles will be enough to prepare a poison that is enough to be placed throughout the apartment.
It makes sense, starting the fight against cockroaches, to buy several bags at once in order to prepare a sufficient number of baits.
In general, compared to the currently popular gels and aerosols, boric acid, of course, is not a very effective tool. Its action is extended in time and very rarely only with its help it turns out 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 home remedies for cockroaches.
If you want to use something much more effective, pay attention to the modern preparation for cockroaches "Lambda Zone". This insecticidal product is practically odorless, safe to use and in practice it turns out to be effective even when cockroaches are resistant to other insecticides.
Good luck with your pest control!
Will boric acid help get rid of cockroaches
And here is a clear example of how GEKTOR powder with boric acid in the composition acts on cockroaches
Thanks, educational. I don’t have cockroaches, but my brother just has a horror, I found your site, dropped the link to him.
Everything is just perfect 😉
Thank you for the information, everything is so detailed. We haven’t had cockroaches for seven years, and then some kind of invasion. I took the advice and now I'm waiting for the results. Thank you!
I live with my wife in a hostel. Cockroaches - darkness. Today poured boron powder. The main place of residence of cockroaches is behind the refrigerator. Let's see what will happen. We keep our fingers crossed, well, we are very tired of them.
We are waiting for the result
Just a powder scattered in paths is ineffective. But balls of yolk and boric acid powder will help a lot. Even if instead of balls you get a liquid, you can spread it on cardboard and spread it out. They did this in a hostel - there were fewer cockroaches (all over the hostel, and not just in our room).
In a two-story fire station with parquet floors, boric acid was sprinkled in the kitchen and in the bedroom, on the baseboards behind the refrigerator. And they didn't wash the floors for a month. And they disappeared once and for all.
Thanks for the advice, I'll try to use it!
I took your advice and am waiting for the result. I made boric acid with an egg 30 gr. for 1 yolk.
So tell me, are you waiting for the result?
Where did you buy boric acid?
At the pharmacy.
Boric acid is better to buy in companies that sell chemical reagents. We have Reakhim in Samara, boric acid costs around 100 rubles per kg.
Thank you.
Thanks everyone for the great advice 😉
Will boric acid help get rid of black cockroaches?
We had black cockroaches climbing out of the sewers. Then ordinary street frogs appeared (we lived in the village), and the cockroaches disappeared on their own, and the frogs too.
Thank you very much, we'll try it
It is best to mix the boiled yolk with boric alcohol, they slowly leave, and they will not be there until they climb in the cellars. It just needs to be refreshed sometimes.
Thanks for the recipe. I hope everything goes well for us.
Only you need to take village eggs, they are tastier)) For seed ...
And if boric acid (powder) is diluted with water and sprayed on the places where they usually live, will it help? And in what proportion?
Maybe someone knows and will tell us ... We have some kind of insects, they are not visible, but traces of their vital activity are everywhere (terrible yellow dots), all things, furniture, etc. sit up with them. All I do is mine and rewash. SES didn't help. This is terrible, I blocked the entire Internet, I can’t find anything, there is a problem, but I don’t know who creates it and how to deal with it ((
Maybe it's a moth.
Boric acid helps, but cockroaches do not disappear completely, then after 2-3 years they reappear.
Best cockroach repellant!
And we have cockroaches in a private house. Probably, my aunt brought it, becauseshe has been fighting with them in the apartment for decades already. There seem to be few of them, but I burned 15 pieces in January in the stove, both large and fat ones, and a couple of small ones.
So, on February 2, I bought boric acid in the evening, mixed 30 g with boiled egg yolk, well, and a little water, for consistency. Spread out everywhere where I saw and did not see cockroaches.
Results for 3 days: February 3 - not a single reptile caught my eye. February 4 - one “greeted” my slipper, saw it in a crushed form - there was some kind of white mess inside. February 5 - in the morning one shamelessly lay on his back, moving his paws, in the evening the second was caught, but cheerfully ran about his business - the insides were black-white-gray.
I'll post back in a couple of weeks with the results. So far, I’m only trying boric acid, for the purity of the experiment and to determine the effectiveness of the method.
I'm waiting for your result. Like in an apartment, one cockroach will come across to me - I immediately processed it with gels. Which I have not tried, for a short time. They treated it with a special spray, it was not visible for half a year. They reappeared. I smeared it with chalk, so there were even more of them. Yesterday I poured boric acid everywhere behind the baseboards, behind the cabinets. I hope for her.
One cockroach was slapped on February 15 and forgotten about. I literally just killed another small one and remembered my review here. Apparently, these balls need to be updated more often than once a month :/
Outcome: the result is, but it is NECESSARY to SUPPORT.
I can’t vouch for the last two that they appeared in the house, perhaps a relative also brought ...
Tell me, please, can I just mix potatoes with boric acid, without an egg?
Can
I have a very large number of these friends, which I just have not tried! And she sprayed the apartment with all sorts of newfangled drugs, and also smeared all sorts of different glues, and even the Regent, who was poisoned by the Colorado potato beetle, did not help. Here, I read tips about boric acid, rolled balls, I'm sitting waiting! Tell me, is it effective?
I'll try. Thank you.
Lived in a dorm for 6 years. This is the only effective remedy for cockroaches, and 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 much do they disappear, provided that the room is constantly kept clean? He also just settled in a hostel and already met such bad guys ((It seems that he completely washed the room, but they don’t want to leave.
Tell me please. Today, I diluted it into two small yolks with one sachet of boric acid and spread it all over the apartment. I understand that this bag will not be enough for them? Can they get even more divorced? And how to be now? ((
I also used boric acid today, treated the whole house, even prepared porridge for them. Now I'm waiting for the result...
And I messed up, instead of the yolk I used protein, it doesn’t work anymore, right, people?
Dana, I need a yolk!
And I mixed a raw egg with bread until a thick mixture and poured 70 grams of boric acid. I rolled the balls and laid them out in their habitats, I'm waiting for the result.
We bought a cottage with cockroaches. There were many. A lot - you go out to the kitchen at night, turn on the light and see 20-30 individuals. They began to poison with boric acid with yolk.I mixed 4 yolks and 3 pharmacy bags, spread the balls everywhere. I didn’t notice the effect right away, after two weeks I didn’t see 20-30, but a maximum of 10, after another week - there were a maximum of a couple, after another two - they were gone. In general, I didn’t see a single living thing anymore, but there were just crowds.
Knowledgeable people advise updating this bait every couple of months and keeping it constantly for half a year.
Well, is there a result from boric acid?
And today I poured boric acid on fried potatoes, they gathered on it. Will this method help?
A bag of 10 grams of acid in our pharmacy costs 47 rubles. In the store "Seeds" - 18 rubles. In chemical stores, a whole kilogram costs only 85 rubles.
I also spread it everywhere today, even behind the toilet and in the bathroom. They got it hard, I open the kitchen cabinets, and they fall on my head! I tried 1000 products, everything is dry at night, not a crumb! And they are so lean, they run!
And we rented an apartment, naturally, during the day we looked, there were 1-5 cockroaches. The owner, I see, scattered the poison, says that this has never happened before, the former tenants did not poison. Came in the evening with my husband to bring a marafet. They turned on the light and ... They ran everywhere: in the kitchen, in the room, and in the bathroom. There are about 20 pieces. I am 8 months pregnant, I urgently need an apartment, there are no options to look for another. In general, I went, bought a gel, they gave me some kind of dilute. In general, I sprinkled this thing, smeared it with gel, sprayed it with dichlorvos, ran away without breathing. Now I’m going to go buy boric acid and roll the balls. I'll see the result. Then I'll write.
By the way, 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, I passed the gel on the baseboards, behind the refrigerator, and sprinkled the raid and left, by the evening everything would disappear and there were fewer cockroaches, 1-2 pieces.
I will poison, I make 5 types. Maybe something will help.
Cockroaches in this way are easy to remove in a private house. But they don't come out of my apartment. I live on the 1st floor. In the basement, fleas are constantly being poisoned with some kind of gas, and it is clear that the Prussians live there too. So, they run to us after the persecution. 4 years I can not withdraw ((
There is a very effective and completely safe remedy for fleas - alcohol tincture of wormwood. The Internet will help you. Only I did not begin to measure with spoons - I poured out half a bottle. And that's it! Never seen again.
Where to pour?
We live on the 5th floor of a five-story building, these bastards climb to us from the ventilation. Nothing takes them - gel, dichlorvos, sticky gel ... We will try acid. Zadolbali.
It must be sealed with a fine plastic mesh. Use a window instead of a hood.
Our upstairs neighbor started repairs and from that moment cockroaches went. We've been suffering for 2-3 months now. The ventilation was closed with a mesh, but we have pipes and meters behind a wooden door and there’s no way to close it tightly ((I’m trying boric acid today ...
Very interesting, thank you all. There were also no cockroaches for ten years, but after a heat of 37 degrees this summer, how they will rush! Is there any connection?
Also appeared after the heat, before it was not.
Anyone who is thinking whether to use boric acid against cockroaches or not? YES! It so happened that we had cockroaches at home, and not a couple, and not 20-30 pieces, as they say 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 me to use boric acid with boiled potatoes. And to my great surprise, cockroaches were dying out, well, just hundreds. I have two kids, so I put the poison at night, in the morning I went to the kitchen, and on the floor they lie in a whole camp! HOWEVER it needs to be supported. The effect is not seen immediately, somewhere on the 5th day. I fought with them for 2 weeks, six months passed, a couple appeared again. I will continue to fight.
Guys, we have +20 in winter in Tashkent, so cockroaches tortured us. I spend the generals every season, from ceiling to floor, every centimeter. After her 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 needs to be updated. 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.
As a child, they lived in a hostel. There were also a lot of them, then they moved, they crawled from their neighbors in the same way. So, the mother brought them out just with boric acid with an egg. Helped. Now, 2 years ago, I moved into a new apartment. Half a year ago, creeping midges divorced, in the summer they destroyed it with dust. Now a new misfortune, cockroaches rod. Negro neighbors. Pigs, everything crawls from them. I will fight with a proven method. Gels and traps don't help. Today poured, I will follow. In the afternoon I will roll more balls. Hate them. It's shaking when I see it.Vile creatures.
I called a chemist, processed for 2 thousand - and no result. I bought a Pest repeller, also for 2 thousand - it has been working for the third month and it’s no use, they don’t care, they run. So who wants to buy this garbage: think, money down the drain. Here, too, I'll try the old-fashioned boron. At least it's cheap.
Hello! Followed the advice and bought boric acid. I made balls, scattered them around their habitats. But the remedy doesn’t help ((There are even more of them in the kitchen than usual. Previously, they were afraid to climb out into the light, but now they are already running insolently and are not afraid. What should I do now if the remedy does not help?
Daria, there really are more of them at first, we ourselves got scared. It seemed to me that people from all over the house came to visit us)) Read my experience below.
Is an alcoholic solution of boric acid suitable?
Hello! I live in a Stalinist building, a communal apartment. As long as I can remember, there were so many cockroaches that goosebumps. If you go to the kitchen at night, then the whole riser was a carpet of cockroaches, and there were a lot of them in the rooms.
I was advised boric acid with an egg. They laid out around the perimeter of all rooms, every half a meter, half a teaspoon (in places where there were especially many of them, they put more). They even laid them out on cabinets and bedside tables. After 3 days, they took out 1.5 buckets of cockroaches. Repeated after 2-3 weeks, I do not remember exactly.
From 1999 to 2016 I HAVE NOT SEEN A SINGLE COCKROACH!
They told me that for 15 years they would forget the way to the apartment)) It is very important to repeat! Hope my advice helps.
Boric acid is the only drug to which the mustachioed cockroach has not yet adapted.To other poisons (any) cockroaches can develop resistance (if you use the same drug regularly).
And we have a problem. About 10 years ago, we brought out the whole horde with boric acid. Now one of the neighbors again divorced. Darkness is dark. I made, like that time, balls with boric acid, yolk and potatoes. Those bastards don't eat them. They just ignore
Raw eggs or boiled?
They write here that cockroaches were brought out for ten years. So they were nowhere to be found! They completely disappeared for about 10 years, from 2000 until recently. Everyone wondered where they had gone, what kind of radiation) Really? Or maybe I thought so, and somewhere they still were. Just wondering. I was already glad that it was forever they disappeared from the face of the earth. But here they are again.
Our cockroaches also disappeared about 12 years ago, and about 7 years ago they began to slowly appear, but then I installed wi fi for myself and they disappeared, maybe not for that reason, but I heard several similar stories. They reappeared about 5 years ago. 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, what started, just a darkness of cockroaches, and at the same time - both small and large, and thin, and fat. I will use boric acid again. Dusta powder also helped me, but the stench is impossible, and it’s still poison, 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 are scattered.They really liked the yolk with butter, but the boric acid remained untouched)) Maybe I got one, or ants with armor protection ...
Tell me, please, is technical boric acid suitable for cockroaches?
Yes, that's exactly what it was! And now it seems like new, more stable ones have returned (((
