How to Kill Bacteria Naturally

While chemical disinfectants will kill most bacteria found in the home, you may wonder whether using them is worth the risk and expense. Harsh chemical ingredients in disinfectants can be dangerous if ingested, particularly for children, and may cause skin and respiratory problems. Many people look to natural solutions to kill bacteria. For most households, natural disinfectants are a safe and efficient alternative to chemical disinfectants.

Instructions

1

Fill a clean spray bottle with straight vinegar or create a mixture with water. A 5 percent solution of vinegar, found in most supermarkets, kills 99 percent of all bacteria, according to Annie B. Bond on Care2. For best results, spray the infected area and let the vinegar sit overnight before wiping down. The smell will dissipate after a few hours.

2

Mix hydrogen peroxide and water in equal parts in a clean spray bottle. The bottle should be opaque because light will break down hydrogen peroxide. If the bottle is not opaque, store it in a dark place, such as under the sink. Then check the mixture for bubbles before using to ensure the hydrogen peroxide is still active. Hydrogen peroxide has been recognized as an effective disinfectant by the Environmental Protection Agency since 1977. Spray the mixture on a hard, nonporous surface and let it sit for several hours before wiping away.

3

Shake baking soda onto the infected area and let it sit for several hours before wiping away. Another option is to mix baking soda with water, then use the mixture to scrub down infected areas.

4

Keep spray bottles of hydrogen peroxide and vinegar handy to disinfect counters and food, such as vegetables and fruit. Spray vinegar on the surface first, then spray on hydrogen peroxide (or vice versa). Rinse thoroughly with water.
