Borax—scientifically known as sodium borate—is a naturally occurring mineral that has been used for more than a century in household cleaning, deodorizing, and pest management. Thanks to its versatility, affordability, and effectiveness, borax remains a staple in many homes around the world. Among its lesser-known but highly practical uses is a simple trick: sprinkling borax on wax paper and sliding it under your refrigerator. This surprisingly effective method helps address hidden problems that often occur in the dark, hard-to-reach space beneath kitchen appliances.

In this SEO-optimized article, we dive into the science behind borax, how this method works, and why homeowners continue to rely on this natural mineral. Supported by trusted sources such as the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention (CDC), and University of Florida IFAS Extension, this guide will show you exactly how borax can improve your home environment safely and efficiently.

What Makes Borax So Useful? An Overview of Its Properties

Borax is a fine, white powder with mild alkaline properties. It dissolves easily in water and enhances the performance of soaps, detergents, and cleaning agents. According to the EPA, borates are highly effective at controlling mold, neutralizing odors, and deterring certain household pests.

Some of borax’s most important features include:

• Deodorizing ability: Neutralizes acidic and bacterial odors

• Mild disinfecting power: Helps reduce microbial buildup

• Pest-repelling properties: Interferes with insect digestive systems

• Water softening effects: Improves cleaning performance

Because of these characteristics, borax has remained a trusted household helper for generations.

Why Put Borax Under the Fridge? The Benefits Explained

Placing borax on wax paper and sliding it beneath your fridge offers several practical benefits:

1. Effective Pest Control

Warm, dark spaces—like the area beneath refrigerators—often attract ants, cockroaches, and other insects. According to University of Florida IFAS Extension, borax disrupts insects’ digestive systems when ingested. This makes borax a powerful tool for discouraging pest activity in hidden areas.

2. Odor Absorption and Air Freshening

Food particles, spills, and moisture can accumulate under the fridge over time, causing unpleasant odors. The CDC notes that borates help neutralize odor-causing molecules. When placed under the fridge, borax absorbs lingering smells and helps keep your kitchen environment fresh.

3. Low-Maintenance and Easy to Replace

Using wax paper beneath the borax allows for effortless cleanup. Simply remove the sheet and replace it every few weeks or months as needed.

Step-by-Step Guide: How to Use Borax Under Your Fridge

Here’s how to apply this trick safely and effectively:

1. Cut a piece of wax paper large enough to cover the width of the fridge bottom.

2. Sprinkle a thin, even layer of borax across the wax paper.

3. Slide the sheet under the fridge, pushing it fully to the back.

4. Check and replace the sheet every 4–8 weeks depending on odor and pest levels.

The wax paper helps keep the borax contained while still allowing insects to come into contact with it.

How Borax Works Against Pests

Borax is toxic to insects but generally safe for adults when handled properly. According to the EPA:

• Borax works as a stomach poison when insects ingest it.

• It destroys essential enzymes in their digestive systems.

• Over time, it wipes out pest populations that crawl through or eat it.

Although not an instantaneous solution, borax is highly effective when used consistently, making it a popular natural alternative to harsh chemical pesticides.

Odor Control: Why Borax Neutralizes Smells

Odors under appliances typically come from acidic byproducts of food decomposition. Borax neutralizes these acids on contact. This makes it especially helpful in:

• Kitchens

• Utility rooms

• Damp or enclosed areas

By absorbing moisture and odor compounds, borax helps maintain a cleaner, fresher-smelling kitchen without the need for perfumed sprays.

• Avoid inhaling the powder during application.

• Use gloves if you have sensitive skin.

• Store borax in a tightly sealed container.

• Do not use borax directly on food-preparation surfaces.

Following these guidelines ensures borax remains a safe and effective home remedy.
