There is no doubt that none of us likes to see a cockroach in the house, but apparently, they are not easy to be destroyed.
Namely, they can vanish and reappear again soon. Moreover, they leave a horrible odor after them, and the commercial products on the market against cockroaches are simply loaded with dangerous chemicals.
Yet, there is a recipe that effectively eliminates cockroaches, and does not include any of those toxic ingredients. This is how to prepare it:
In a raw egg yolk, pour 30-50 grams of boric acid powder (borax or boric powder acid), and stir well, in order to get a slurry mixture. Then, make small balls from the mixture, with a diameter of 1cm, and leave them to dry.
After an hour, when they are completely dry, you can place them all around the house, on common areas for these unpleasant visitors, corners, in the kitchen, in the bathroom.
Yet, you should keep in mind that these places should be visible from the point of cockroaches, like kitchen cabinets, shelves, closets, and racks.
Initially, cockroaches will come out of curiosity, and will go and investigate the boric ball. They will start to touch them with the mustache, and that is all that is needed for them to be destroyed, even before they can warn the others about the danger.
What is best about it all is the fact that these balls are not dangerous for you or your pets, so you can distribute them freely around the house and close to your dogs, cats, or children.
Boric acid is used for disinfection and is not toxic. 3% boric acid is actually acidi borici, eye wash solution. Hence, if you cannot find boric acid powder, a 3% solution of boric acid can also be used and provide the same effects.
Furthermore, these balls will attract more and more bugs, and make them severely ill, so they can even infect other healthy counterparts by touching them only.
At first, you may get the impression that the boric balls do not work as cockroaches will move calmly, but in 3-4 weeks, you will get rid of all f them!
Every day, you will have to clean a pile of dead bugs, and you will finally solve this unpleasant issue.
Yet, if they appear again in 6 months, it means that female cockroaches have succeeded to lay eggs, and that is their new generation. However, you can get rid of it, in the same way, using the miraculous boric balls.
