Doubt you even need to try the peroxide. For one thing what are the "centipede type things" you have? Size, color, damage if any? And when it comes to fungus gnats, pull back on how you water. The simplest thing to do is to allow the soil surface to dry. But to get a running start on stopping the gnat's life cycle, use Bacillus thuringiensis israelensis (either Mosquito Dunks or the granular form) in the water you give to your plants. Realize that it takes several weeks to stop the life cycle. And those "unknown yellow round clusters of eggs" may well be Osmocote, a slow-release fertilizer.

About the stabilizer chemicals in the 3% HP. From what I have read, these chemicals accumulate and are toxic to humans. If they are being sprayed on plants would it not have the same effect? Poison? I will not be using 3% anywhere in my home and am looking for a supplier of 35% food grade. I will also use it as an alternative to chlorine in my pool. Here are the differences for your readers. An excerpt from: The Many Benefits of Hydrogen Peroxide By Dr. David G. Williams http://educate-yourself.org/cancer/benefitsofhydrogenperozide17jul03.shtml Posted July 17, 2003 (Original title: Hydrogen Peroxide - Curse or Cure?) Grades of Hydrogen Peroxide Hydrogen peroxide is available in various strengths and grades. A) 3.5% Pharmaceutical Grade: This is the grade sold at your local drugstore or supermarket. This product is not recommended for internal use. It contains an assortment of stabilizers which shouldn't be ingested. Various stabilizers include: acetanilide, phenol, sodium stanate and tertrasodium phosphate. B) 6% Beautician Grade: This is used in beauty shops to color hair and is not recommended for internal use. C) 30% Reagent Grade: This is used for various scientific experimentation and also contains stabilizers. It is also not for internal use. D) 30% to 32% Electronic Grade: This is used to clean electronic parts and not for internal use. E) 35% Technical Grade: This is a more concentrated product than the Reagent Grade and differs slightly in that phosphorus is added to help neutralize any chlorine from the water used to dilute it. F) 35% Food Grade: This is used in the production of foods like cheese, eggs, and whey-containing products. It is also sprayed on the foil lining of aseptic packages containing fruit juices and milk products. THIS IS THE ONLY GRADE RECOMMENDED FOR INTERNAL USE. It is available in pints, quarts, gallons or even drums. Various suppliers are mentioned later in this article. G) 90%: This is used as an oxygen source for rocket fuel. Only 35% Food Grade hydrogen peroxide is recommended for internal use. At this concentration, however, hydrogen peroxide is a very strong oxidizer and if not diluted, it can be extremely dangerous or even fatal. Any concentrations over 10% can cause neurological reactions and damage to the upper gastrointestinal tract. There have been two known fatalities in children who ingested 27% and 40% concentrations of H202. Recently, a 26 month old female swallowed one mouthful of 35% H202. She immediately began vomiting, followed by fainting and respiratory arrest. Fortunately, she was under emergency room care and although she experienced erosion and bleeding of the stomach and esophagus, she survived the incident. When she was re-examined 12 days later, the areas involved had healed (J Toxicol Clin Toxicol 90;28(1):95-100).

I have a custom made tray for whitening my teeth. I used to get the whitening solution from the dentist but found I could buy it on Amazon for much less. One time I ordered the extra strength variety and left it on for about an hour. I almost flipped when I took off the tray and looked in the mirror. I had bleached my gums in front totally white! Fortunately the pink color came back in about 20 minutes but I was afraid I would have to walk around looking like that. The whitening agent has peroxide in it. I use something called Opalescence. The extra strength is 35% peroxide. I don't think it's a good idea to use straight peroxide on your teeth for any length of time. Swooshing is okay. I remember that some people use it to treat gum disease, a cause of bad breath. Before I whiten my teeth I brush them with baking soda to get them extra clean. Another good time to whiten is right after they have been cleaned. For me, baking soda is too abrasive for every day use. My dentist does not recommend it. He does recommend rinsing with Listerine.

Hydrogen peroxide works on fairly fresh stains but you still need to test on an inconspicuous area. DH has a beautiful white terry cloth robe that the kids gave him for father's day and he managed to get some blood on it. He used hydrogen peroxide which took out the blood stain but it also yellowed the robe. I've never had that happen before. The robe was 100% cotton and the label tag said not to use a chlorine bleach. I've had positive experiences with Clorox totally Spotless Feminine Stain Remover. I hate the name and wrote them a letter complaining about it but the product does work. According to the label it contains Hydrogen Peroxide, Nonionic Surfactant. I have no idea why it should work any better that plain hydrogen peroxide but it has even removed some older blood stains.
