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!
