Here's what I did:
You'll need spray bottle, metal scrubber and a bucket.
Put boric acid in the bucket and water, you want to make it a little bit thicker than a solution, scrub down every single tile floor, wall, soap holder, etc... in your bathroom, if you have any discolored areas, scrub them till they're gone, every home has mold and mildew in it, bleach does not kill 100% of mold and mildew, despite popular belief.
What it doesn't kill, it bleaches....great way to not solve a problem, plus it's toxic in confined areas.
Do not rinse it off, leave it for 20-30 mins, rinse it and air the place good to get rid of the humidity.
Also, on the carpeting, put the powder on the carpet, and brush it with your hand to make it go in, that will kill mold, mildew and boric acid is extremely toxic to insects.
Now, after your shower in the morning, put some boric acid in your shoe, sprinkle it over your feet, making sure it goes in toe nails, etc....
If you follow that, you will see results within a few days/week.
A few pointers:
-Boric acid is not toxic, it as "toxic" as table salt.
-You will notice less insects in your house.
-Most fruits have boric acid in them.
-Boric acid is the only acid beneficial to the human eyes. (DO NOT put it in your eyes though, it must be prepared to a certain concentration under sterile conditions)
-It's the only thing that ever worked for me without any side effects and minimal cost for Athletes foot and acne, it works great on acne, a little bit of powder with a few drops of water left on the face for a few hours or over night.
