Borax is a relatively low-risk pesticide that is poisonous only by direct ingestion — that makes it an all-favourite tool for cockroach extermination. You can use either borax or boric acid, there’s not much difference in effect, but boric acid is more effective. Boric acid can be made from Borax and hydrochloric acid. Find other homemade recipes for dealing with cockroaches in our article.
Borax must be mixed with bait —it doesn’t attract roaches on its own— and then spread as a powder or sprayed in a mix with warm water. You may need to apply Borax several times, the exterminating process can be slow, but it will kill all the roaches eventually. Just make sure that you’ve spread it in all the infested areas and those that are preferable for infestation (kitchen and bathroom sinks, electrical outlets and anything that smells bad).
You can buy regular Borax like Milliard Borax powder or a Borax-based insecticide like Zap-a-Roach Boric Acid Roach and Ant Killer.
