A Simple Borax Trick to Keep Ants and Roaches Away
Household pests can quickly turn from a minor annoyance into a major headache. If you’ve ever battled an ant trail in the kitchen or spotted roaches darting under appliances, you know how hard it can be to keep your home truly pest-free.
One surprisingly effective and low-cost method uses just three things: borax, wax paper, and the space under your refrigerator. This old-school hack is becoming popular again because it’s simple, discreet, and can help control pests without relying on harsh chemical sprays.
Below is how it works and how to use it safely in your home.
What Is Borax?
Borax (sodium borate) is a naturally occurring mineral used in:
- Laundry boosters and cleaning products
- Homemade cleaners
- Certain insect control products
Because borax has strong insecticidal properties, many homeowners use it as part of a natural pest control strategy, especially against ants and cockroaches.
How Borax Affects Ants and Roaches
Borax doesn’t just repel insects—it helps eliminate them.
Here’s what it does:
-
Acts as a stomach poison
When ants or roaches ingest borax (usually mixed with something they’re attracted to, like crumbs or other food residues), it disrupts their digestive system, eventually killing them. -
Damages their exoskeleton
Borax is slightly abrasive. When insects crawl over it, it can scratch and damage their outer shell, causing them to lose moisture and dehydrate. -
Targets the colony, not just individual insects
Ants often carry tiny particles of borax back to their nest, spreading it to other ants, including the queen. Over time, this can help reduce or even wipe out the colony, not just the workers you see in your kitchen.
This combination of ingestion and dehydration makes borax a powerful tool for controlling household pests when used correctly.
Why Use Wax Paper with Borax?
Wax paper plays a practical and safety-focused role in this method:
- Easy to handle: It gives you a clean, flat surface to distribute the borax evenly.
- Reduces direct contact: The borax stays on the paper instead of directly on your floor, helping to limit accidental contact by children or pets.
- Prevents mess: Wax paper allows you to slide the treatment under your fridge without spilling powder everywhere.
- Controlled placement: You can place borax exactly where pests travel, rather than scattering it broadly around your kitchen.
Using wax paper turns borax into a contained and targeted pest control solution.
Why Place Borax Under the Fridge?
The space beneath your refrigerator is one of the most attractive spots in your kitchen for insects:
- Warmth: Fridges generate heat, creating a cozy environment for pests.
- Moisture: Condensation or minor leaks can provide water for insects.
- Food debris: Crumbs, spills, and grease often accumulate under appliances where they’re rarely cleaned.
This combination makes under the fridge a high-traffic zone for ants, roaches, and other insects. Placing borax there increases the chances that pests will walk through it or consume food particles mixed with it.
How to Use Borax and Wax Paper Under Your Fridge
Follow these simple steps to set up your borax trap safely and effectively.
1. Gather Your Supplies
You’ll need:
- Borax powder
- A sheet of wax paper
- Scissors
- A small spoon or a piece of cardboard for spreading
2. Cut the Wax Paper
- Cut a piece of wax paper large enough to cover part of the area under your fridge.
- A piece around 12 x 12 inches (30 x 30 cm) works for most refrigerators, but you can adjust based on the space available.
3. Spread a Thin Layer of Borax
- Sprinkle 1–2 tablespoons of borax over the wax paper.
- Use a spoon or cardboard to spread it into a thin, even layer.
- You don’t need a thick pile—just enough to lightly coat the surface.
4. Slide the Wax Paper Under the Fridge
- Carefully slide the wax paper under the refrigerator.
- Aim for an area where you suspect insects are traveling or where food debris tends to collect.
- Ensure the borax stays on the paper and doesn’t spill onto the floor.
5. Check and Replace Periodically
- Inspect the wax paper every few weeks.
- Replace it if:
- The borax looks dirty
- The paper is wet or damp
- There are visible signs of heavy insect activity
- To replace, carefully remove the old sheet, discard it, and slide in a fresh one.
Advantages of This Borax Method
Using borax on wax paper under the fridge offers several key benefits:
1. Lower Toxicity for Humans and Pets (When Used Properly)
- Borax is toxic to insects but is generally less harmful to humans and pets when handled correctly and kept out of reach.
- The wax paper barrier helps reduce direct contact with the powder.
Note: “Low toxicity” does not mean harmless—borax should still be handled with care and never ingested.
2. Budget-Friendly Pest Control
- Borax is inexpensive and widely available.
- A single box can last a long time compared with buying repeated doses of commercial sprays or hiring professional pest control.
3. More Environmentally Friendly Than Many Synthetic Pesticides
- Borax is a naturally occurring mineral, not a synthetic chemical.
- It doesn’t carry the same environmental concerns as many conventional insecticides when used responsibly.
4. Long-Lasting Protection
- Once placed, borax can remain effective for months, as long as it stays dry and relatively clean.
- This means you get ongoing pest control with minimal maintenance.
Safety Tips When Using Borax at Home
Even though borax is considered safer than many chemical pesticides, you should still treat it as a chemical substance and use it carefully.
Follow these precautions:
-
Keep it out of reach of children and pets
- Ensure kids and animals cannot reach under the fridge or pull out the wax paper.
-
Avoid breathing in the powder
- When handling borax, try not to create dust.
- If you’re sensitive, you can wear a simple mask and gloves while setting it up.
-
Do not ingest
- Borax should never be eaten or used on food surfaces.
- Wash your hands after handling it.
-
Store borax correctly
- Keep it in a tightly sealed container.
- Store it in a cool, dry place, away from food, drinks, and areas where it could be mistaken for something edible.
A Simple, Low-Cost Strategy for a Pest-Free Kitchen
Using borax on wax paper under your fridge is a straightforward, discreet, and affordable way to help control ants, roaches, and other crawling insects in your home. By targeting a spot where pests are naturally drawn—warm, dark, and often full of crumbs—you increase the chances of them encountering the borax and carrying it back to their nest.
With basic safety precautions and occasional monitoring, this method offers:
- Long-lasting protection
- Less reliance on harsh chemical sprays
- A cleaner, more pest-resistant home
By understanding how borax works and using it strategically, you can take a simple yet effective step toward keeping your kitchen cleaner, safer, and more comfortable.
