The principle of action and recipes for the use of boric

The fact that in the apartment or house cockroaches started is pleasant enough. These insects cause disgust in humans. But their harm is not only in this. Cockroaches can be carriers of dangerous diseases. There are many tools that will help you get rid of such an unpleasant neighborhood. When choosing an insect repellent, try using boric powder (acid). This is an inexpensive drug that can help you, if used correctly, solve this problem.

How does boric acid act on cockroaches?

How does boric acid act on cockroaches?

When buying boric acid, you will see that it looks like a white powder, consisting of grains. Acid grains differ in size and shape. As a poison for cockroaches, boric acid is good because it has no taste or smell. However, for insects it is toxic. In addition, boric acid has a good antiseptic effect.

Each person can buy such acid in the pharmacy. On the shelves it can be found in 2 types. One of them is packing bags, which contain white powder, the other is an alcohol solution in a vial of dark glass. It should be said here that a solution of boric acid, which is called boric alcohol, is not as effective in its properties as a powder. It is better not to use boric alcohol to fight cockroaches, as its smell repels insects.

As you know, cockroaches can survive even radiation exposure, but simple boric acid is poison for them. When it enters the insect's digestive system and then through the blood into the nervous system. Here the acid provokes paralysis in the cockroach, and then suffocation occurs. It is clear that in order for the poison to begin to have an effect, it must get inside. To do this, it is necessary to make the poisonous substance, in this case, boric acid powder, work like a bait. Moreover, the cockroach should eat the bait with poison in large quantities. To do this, it is not necessary to mix different foods with acid; you can simply sprinkle the powder in the places where insects are most concentrated. Most often, cockroaches are located near the baseboard, by the bedside table or in the area of ​​the trash can. Therefore, poisoning agents are best placed in such places.

If the powder remains simply on the limbs of a cockroach, this will be quite enough. In this case, the poison will still enter the body to the insect when the insect begins cleaning its limbs. Theoretically, in order to get rid of a large number of cockroaches, 5 g of boric acid would be enough. But in fact, more raw materials are needed, because it is not at all necessary for the cockroach to crawl exactly to the place where the poison is scattered.

Actually, the dispersion of boric acid in places where cockroaches accumulate is the first way to combat them with this substance.

The feedback on this method of dealing with these insects is mostly positive. People say that after they scattered boric powder around the sink and the toilet bowl, the cockroaches were gone forever. The tool may not work if it is used incorrectly. If there are cockroaches that have not received the necessary amount of poison, they will feel the danger and leave the apartment. If the home is hit too hard by the cockroaches, you should add boric acid to various baits and place such tools in different places of the apartment.
