Borax, or sodium borate, is a naturally occurring mineral long valued for its remarkable versatility in household care. For decades, it has been used for cleaning, deodorizing, laundry enhancement, and even light pest control. However, one lesser-known—but incredibly useful—application involves sprinkling borax on wax paper and sliding it beneath your refrigerator. Although simple, this clever method can tackle several common household concerns in a cost-effective and low-effort way. Below, we break down why this trick works and how to use it properly.

Understanding the Properties of Borax

Borax is a fine, powdery white mineral that dissolves readily in water. Mildly alkaline in nature, it serves as an excellent cleaning aid by breaking down grease, neutralizing acids, and boosting the performance of soaps and detergents. Its natural deodorizing qualities help eliminate unpleasant smells instead of masking them, and its ability to deter certain insects makes it a multifunctional tool in home care. Because it is both affordable and long-lasting, many households keep a box of borax on hand for a wide variety of maintenance tasks.

Why Place Borax Under the Fridge?

Sliding borax beneath the refrigerator may seem unconventional, but it delivers several practical advantages:

1. It helps deter common kitchen pests

Warm, dark areas under appliances are ideal hiding spots for cockroaches, ants, and other insects. Sprinkling borax in this zone creates a barrier that discourages pests from settling or traveling through these spaces.

2. It absorbs lingering odors

Food crumbs, spills, and moisture often accumulate under the fridge without homeowners realizing it. Over time, these can produce stale or sour smells. Borax acts as a natural deodorizer, neutralizing odors and helping keep your kitchen environment fresh even in areas you can’t easily reach.

3. It simplifies ongoing maintenance

Because the borax sits on wax paper rather than directly on the floor, you can easily slide it out, replace it, or refresh it whenever needed—no scrubbing required.

How to Use Borax Under the Fridge: Step-by-Step

1. Cut a piece of wax paper large enough to reach most of the area beneath the refrigerator.

2. Sprinkle a thin, even layer of borax across the surface of the wax paper. A light dusting is effective; you don’t need a thick pile.

3. Carefully slide the wax paper under the fridge, using a ruler or a thin piece of cardboard if necessary.

4. Replace it every 1–2 months, or sooner if you notice moisture or heavy dust accumulation.

This method keeps the borax contained while allowing it to work continuously without creating a mess.

How Borax Controls Pests

Borax is mildly toxic to insects like ants and cockroaches. When bugs walk through the borax powder, it clings to their bodies and is later ingested during grooming. This disrupts their digestive systems and ultimately kills them. While borax alone won’t eliminate large infestations, it serves as an effective deterrent and helps prevent pests from entering commonly affected areas, such as the space beneath your refrigerator.

How Borax Eliminates Odors

One of borax’s most powerful qualities is its ability to neutralize acidic odors. Instead of simply covering up smells, borax chemically balances and absorbs them. By sitting under the fridge—an area prone to unseen spills, moisture, and organic debris—borax helps keep the entire kitchen smelling cleaner and more pleasant without any strong artificial fragrance.

Safety Tips When Using Borax

Although borax is generally safe when used properly, you should:

• Keep it away from children and pets, as ingestion can be harmful.

• Avoid inhaling the powder when sprinkling it.

• Wear gloves if you have sensitive skin.

• Store borax in a tightly sealed container in a cool, dry place.

Using it responsibly will ensure you benefit from its effectiveness without unnecessary risks.

Other Useful Household Applications of Borax

Borax’s versatility goes far beyond pest control and odor removal. Many homeowners also rely on it for:

• Laundry boosting to improve detergent performance

• Removing stains from carpets, upholstery, and clothing

• Cleaning mold and mildew, especially in damp bathrooms

• Deodorizing garbage cans, drains, and refrigerators

• Scrubbing sinks, tubs, and tile grout thanks to its mild abrasiveness

Because it is both inexpensive and long lasting, borax remains a reliable staple for natural, non-synthetic cleaning routines.
