Of all the folk remedies from cockroaches, boric acid is known, perhaps, more than all the others. Recipes of poisonous mixtures with it so much that pests can be called true gourmets.
Boric acid is applicable in almost all rooms and situations. However, for all its universality, this powder has its own characteristics, positive and negative. Therefore, it is necessary to know how to poison cockroaches with boric acid before deciding whether to use it: in some cases it may be more appropriate to use other methods.
Boric acid under ordinary conditions is white grains, similar to flakes. It has no smell and taste, melts at 170 ° C, while gradually losing water and changing the chemical composition.
On a note
Bura is a salt of boric acid, widely distributed in nature. Its formula is Na2B4O7 * 10H2O. The borax is as toxic to insects as the acid itself, and the remedy for cockroaches with boric acid or borax will work equally efficiently.
In nature, the reserves of pure boric acid are very limited. It is a part of the mineral sassolin, which is found in small quantities in the Mediterranean and the Middle East. Dissolved substance is present in many mineral waters.
The so-called "boron powder" is a known antiseptic, and therefore is sold in pharmacies in both powder form and in dissolved water or alcohol form. It is her solution in 70% ethyl alcohol called boric alcohol.
On a note
Boric alcohol from cockroaches is much less effective than other forms of boric acid. This is due to the fact that the Prusak deters the smell of alcohol itself, and therefore they can not poison acid. At the same time boric powder from cockroaches is almost invisible to them, and this is the basis for the principle of the drug.
The effectiveness of boric acid against cockroaches
For cockroaches, as for most other insects, boric acid is a strong poison. The action of boric acid on cockroaches is that, entering the digestive tract of an insect, 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 it dies of suffocation.
Accordingly, in order for boric acid against cockroaches to be effective, it is necessary that the cockroach swallow it, and preferably in a large number by the standards of insect. Therefore, any remedy for cockroaches with boric acid is used to make insects eat it , and questions like "How to stain cockroaches with boric acid?" Are in principle incorrect - these pests do not seethe powder, but are poisoned, so to speak, with pleasure.
It is not necessary to cook boron balls from cockroaches with the addition of eggs, flour, vanilla or other ingredients, 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 skirting, along the perimeter of the base of the bedside tables, under the sink. After the pest has run through the powder, the particles will remain on its paws. Then, in the shelter, the insect will begin to clean the feet with jaws and involuntarily swallow the powder itself. With all the outgoing consequences.
A solution of boric acid from cockroaches is also quite effective if it is introduced into edible baits.
To poison one pest, 2-3 mg of the drug is sufficient. Consequently, a 10 gram bag sold in a pharmacy, in theory, will be enough to destroy many thousands of insects. However, in practice, the control of cockroaches with boric acid requires significantly higher poison costs, since the bulk of the drug is consumed "idle," and insects never meet with it.
It is interesting
In addition to the Prussians, this means effectively destroys domestic ants, working on the same principle. But against bugs home boron powder is absolutely useless: these parasites can only eat by sucking blood with the help of their proboscis. Accordingly, even with a strong desire, bedbugs can not eat such a poison.
Today, because of the frequent and widespread application of boric acid, cases where it does not help are becoming increasingly common . This is due to both the misuse of the substance and the appearance of insects resistant to it. In such cases, there are meanings of application against pests of more modern means.
"And when we entered the hostel literally kilograms, this boric powder was scattered under the beds. It does not work against Russian cockroaches, only powerful German preparations are needed ... "
In order for cockroaches and boric acid to meet in the apartment, it is necessary either to attract pests to it, or to place poison where insects constantly move.
In the simplest case, it is sufficient to scatter the substance with thin tracks around the shells, the toilet bowl and the bathroom. It is from these tanks that cockroaches constantly drink water, and when they "go to the watering hole" through placers of poison, they are most likely to be infected.
On a note
Sometimes it will be effective to put a saucer near the sink with a solution of the remedy. If the shell itself before poisoning cockroaches with boric acid, wipe it dry, depriving insects of another source of water, you can force them to drink poison - cockroaches badly need regular drinking.
In any case, the path of the drug should be scattered wherever cockroaches are found especially often. Even before fighting cockroaches with boric acid, you can visit your kitchen and bathroom a couple of times at night and check where the mustachians run away when the light is turned on - these are the places to enter their shelters, near which you should put poison.
Feedback on the use of boric acid:
"When I saw the cockroaches in the apartment, I almost died of horror. In general, I can not stand them. Immediately went to the pharmacy, bought boric powder, as advised on the forum, scattered around the sink and toilet, a few days did not wash off. After that, I did not see them, although there were not many of them at all. "
Already such measures should give the result: the main part of the cockroaches must die out, others, under-eaten, just leave the apartment. But if the room is infected too much, fighting with cockroaches in the apartment with the help of boric acid should also be carried out with the help of special poisoned baits.
There are a lot of bait recipes with boron powder, and they can be invented independently. The simplest and most famous of them are:
- One 40-50 grams of powder is added to one raw egg yolk and everything is thoroughly mixed until a thick, gruel-like mass is obtained.
- Boric acid in equal proportions is dismounted with powdered sugar and flour, after which it is kneaded on water to obtain a dough.
- 200 grams of boric acid are mixed with 60 grams. sugar powder, 60 grams of starch and 20-30 grams of vanilla sugar, they add water so much to make a thick and sticky mass.
- One potato is brewed in a uniform and cleaned. The egg is brewed, the shell is removed from it. Potatoes and eggs are rubbed in puree, in which 1 tablespoon of boric acid is added.
From the mixes rolled small balls or flat cakes that 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 yummies in the room, there is no longer any other food for cockroaches: all products must be hidden in the refrigerator, closed in jars or plastic bags, crumbs from the table wipe, and put the garbage out for the night.
It is advisable, before the cockroaches are soaked in boric acid, to carry out thorough cleaning and wash the floors and walls behind and under the bedside tables and kitchen furniture.
The same is true when preparing poisoned drinkers: if cockroaches have a choice - to drink from a new drinker or the usual flower pot or toilet bowl - they will prefer their usual option. So cleanliness is the key to success.
Destruction of cockroaches with boric acid never gives 100% result: insects that find other sources of food and water, or skilfully bypassing poisoned paths, will remain in the room. Nevertheless, if there are very few pests in the apartment, and as a whole the apartment is clean and tidy, it makes sense to resort to this facility.
In dirty old apartments, full of cockroaches and surrounded by no less infected rooms, boric acid at best will help to slightly reduce the number of insects. Therefore, before you remove the cockroaches with boric acid, you should restore order in the room.
Boric acid in the apartment: is it dangerous or not?
For all its toxicity for cockroaches, boric acid is not dangerous for people and other warm-blooded inhabitants of apartments - 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. Because today this substance is replaced by more effective and safe substances.
"I'm so funny to listen to how mummies are afraid of boric acid to buy from cockroaches. Like, poisonous. As a child, when we were young, instead of a green, the scratches were smeared, and nothing arose. Grasp and do not be afraid, nothing will happen to the children. "
Marina Vitalevna, Ust-Kamenogorsk
In any case, this weak acid will not cause poisoning in the child or a four-legged friend who accidentally finds a ball of cockroaches or scattered powder. Therefore, it can be safely used, getting rid of cockroaches.
It is interesting
Bura is just as low in toxicity 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 with accidental use of harm, the body will 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 the Internet. The price of a bag of 10 grams is about 50 rubles, and for cooking the poison, which is enough to accommodate the entire apartment, it will be enough about 250-500 rubles.
It makes sense, starting the fight with cockroaches, to buy several packages at once, in order to prepare enough baits.
In general, compared with popular today's gels and aerosols boric acid, of course, is not a very effective tool. 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 accessibility, safety and cheapness make it one of the most widely used means of cockroaches in everyday life.
Success to you in the fight against insects!
