Given the above summary, write a detailed text in English for it.
Make sure it is clean, inert, clearly labelled container and free of moisture. Proper storage and labeling is key to maintaining safety and avoiding accidentally ingesting the product, as it is visually quite similar to table salt. Avoiding moisture will prevent unwanted large chunks from forming.  A recycled ketchup bottle can be used as a kind of bellows to distribute the insecticide powder in the tight space of an electrical outlet with minimal risk. Squeeze the bottle to test and make sure dust comes out (take care to not get any in your eyes, mouth or nose). Make sure the hole of the bottle you’re using is large enough for the borax crystals to go through freely. Borax is soluble in hot water, as is boric acid and can be dissolved and put in a spray bottle, and the dried residue of aqueous boric acid is essentially undetectable to the insect and low risk to humans.  However, if you are applying it near electrical outlets use it as a powder. It is unnecessary to mix it with bait, as it is not repellant to insects normally, and is tracked by the insect and spread as a surface toxin to other insects.  Once you have covered the areas take care that no food preparation or dusting occurs to prevent accidental ingestion. This is an easy access to interior spaces in walls where roaches live and lay eggs. Spray the borax into the space using your bottle like a bellows, squeezing repeatedly. Replace the outlet covers when done. Do not use dissolved borax. The insecticide will spread among the colony through contact. Complete coverage is desirable, but if any targeted areas have infestations, the insecticide will spread to other insects and kill them, and will not affect the desirability of food to the insects considerably. The borax will destroy eggs and larvae in the carpet. Vacuum up the powder some 20 minutes after application. Any eggs or insects killed will go up with them. Follow any rug care instructions. If you targeted carpeted areas, vacuum a short time after application. Any eggs will be killed in short...
