Boric acid is practically one of the best remedies for cockroaches. If you are curious to know how to get rid of the insects with this, all you have to do is dust a small amount of it on corners and floors and let it sit. Preferably over the night. Another spot where they prefer to stay is under the sink, so be careful to take care of your pipes.
It wouldn’t hurt if you poured a bit of boric acid behind the back of the oven too! But make sure the surface is clean and dry.
Because one thing you should keep in mind is that boric acid is not efficient when it’s wet.
Don’t forget to wash your hands after using it! It’s toxic and it should be kept away from your pets or children.
