You’re sipping your morning coffee, feeling peaceful — until you notice a trail of ants marching across your kitchen counter. Or maybe it’s the faint buzz of fruit flies hovering near the sink, or a line of tiny invaders sneaking under the door. You sigh, knowing what comes next: the chemical smell of sprays, the sticky traps, the endless cycle of wiping, spraying, and hoping.

But what if there was a simpler, safer way — using ingredients you already have in your home?
Believe it or not, two humble household staples — Epsom salt and baking soda — might be the eco-friendly solution you’ve been overlooking. Together, they can help deter, dehydrate, and disrupt pests naturally, without filling your home with toxins.
Sound too good to be true? Let’s uncover how these two pantry heroes could become your new secret weapons against common household pests — and how to use them effectively.
The Hidden Problem With Chemical Pest Control
For decades, the answer to pests has been simple: spray, trap, repeat. But commercial pesticides can do more harm than good. They may leave behind residues that irritate skin, trigger allergies, or even harm pets. Some studies suggest prolonged exposure may affect air quality inside your home.
Beyond that, pests often adapt. Many insect species develop resistance to common chemical treatments, making them less effective over time. So even as you spray, your problem might just be growing.
That’s why more homeowners are turning to natural alternatives — solutions that disrupt pests without harming people, pets, or the planet. And surprisingly, two of the most powerful tools in your arsenal may already be sitting in your bathroom cabinet and pantry.
Meet the Dynamic Duo: Epsom Salt & Baking Soda
At first glance, these ingredients seem unrelated. One is a mineral compound, the other a mild alkali. But when used strategically, they form a potent combination that attacks pests on multiple fronts — from repelling and dehydrating insects to neutralizing odors that attract them in the first place.
Here’s a closer look at what makes each one special.
| Ingredient | Composition | Main Pest-Control Effect | Bonus Benefit |
|---|---|---|---|
| Epsom Salt (Magnesium Sulfate) | Magnesium + Sulfate | Dehydrates and deters soft-bodied pests | Fertilizes plants when used outdoors |
| Baking Soda (Sodium Bicarbonate) | Alkaline compound | Disrupts pest digestion and neutralizes odors | Cleans surfaces naturally |
Together, they create a dual-action effect — drying out pests and eliminating the attractants that keep them coming back.
9 Ways Epsom Salt and Baking Soda Help You Reclaim Your Home

9. Epsom Salt for Ant Control
Ever wondered why ants keep returning to the same spot? They leave behind invisible scent trails to guide others. Epsom salt interferes with that pathway.
Sprinkle it along windowsills, door frames, and baseboards where ants enter. The salt’s texture irritates their bodies and disrupts communication, encouraging them to find another route.
Tip: Mix one part Epsom salt with one part water and spray it directly on entry points for added protection.
8. Baking Soda for Roach Defense
Cockroaches despise baking soda — and not just because it’s messy. When ingested, baking soda reacts with the acids in their stomachs, creating internal pressure they can’t survive.
Mix equal parts baking soda and sugar, then place small amounts near dark corners or behind appliances. The sugar lures them in, while the soda does its work quietly.
7. Natural Fly Deterrent
Flies are drawn to damp areas and odors. Epsom salt helps dry out those environments while baking soda neutralizes smells. Combine both in a shallow dish and place near sinks or trash bins.
You’ll notice fewer buzzing visitors within a few days — and a fresher-smelling kitchen, too.
6. Keep Slugs Away From Your Garden
If your garden looks like an overnight buffet for slugs, sprinkle Epsom salt around the perimeter. The granules act like tiny crystals that irritate soft-bodied pests, making them retreat.
Bonus: Epsom salt provides magnesium for your plants, promoting stronger leaves and richer color.
5. Say Goodbye to Odorous Trails
Many pests — especially ants and roaches — navigate by smell. Baking soda is a natural deodorizer that erases those invisible scent trails.
After cleaning, wipe affected surfaces with a damp cloth and a light dusting of baking soda. You’ll remove not only the grime but also the chemical “breadcrumbs” pests follow.
4. Keep Your Trash Area Fresh
Trash cans are a pest’s paradise: food scraps, moisture, and heat. To keep it under control, sprinkle baking soda at the bottom of your bin and a handful of Epsom salt near the base.
This simple mix absorbs odors and moisture — two major attractants for pests like flies and gnats.
3. Neutralize Moisture-Loving Bugs
Silverfish and earwigs thrive in humid bathrooms and basements. Place open containers filled with Epsom salt in those damp corners to absorb excess moisture and deter these creepy crawlers.
For an extra touch, mix in a few drops of essential oil like lavender or peppermint to add a pleasant scent that pests avoid.
2. Baking Soda for Pantry Protection
Stored grains, flour, and cereals are magnets for pantry moths and weevils. Keep them at bay by storing dry goods with a small sachet of baking soda.
It doesn’t just absorb odors — it creates an environment less appealing to larvae and pests seeking warmth.
1. A Whole-Home Refresh
Here’s where it all comes together. Once a month, do a “salt and soda reset.” Mix one cup of baking soda and one cup of Epsom salt into warm water, and use it to mop floors or wipe surfaces.
This not only cleans deeply but also leaves a fine mineral barrier that naturally discourages insects. It’s a safe, chemical-free routine that protects your home and keeps it smelling clean.
Two Real-Life Success Stories
Case 1: Nora, 53 – The Ant Battle That Ended Naturally
Nora’s kitchen was under siege every spring. After trying sprays and traps, she switched to Epsom salt. “I sprinkled it along the baseboards and under the sink,” she said. “Within days, the ants were gone — and they never came back.”
Case 2: Michael, 45 – The Night the Roaches Disappeared
Living in a warm, humid city, Michael struggled with roaches despite regular cleaning. “I used the baking soda and sugar trick,” he explains. “It felt too easy, but after a week, I didn’t see a single one. I was honestly shocked.”
Both homeowners discovered that simple, natural remedies could outperform harsh chemicals — without risk to pets or kids.
Why This Works: The Science Behind the Simplicity
Epsom salt draws out moisture through osmosis, dehydrating pests on contact. It’s especially effective on soft-bodied insects like slugs and larvae. Baking soda, on the other hand, disrupts a pest’s pH balance, creating an environment they can’t thrive in.
When used together, they address both cause and effect: deterring future infestations while eliminating current ones safely.

| Problem | Recommended Use | How It Works |
|---|---|---|
| Ants | Sprinkle Epsom salt at entry points | Breaks scent trails |
| Roaches | Mix baking soda with sugar | Internal reaction after ingestion |
| Flies | Combine both in dishes near sinks | Absorbs moisture, neutralizes odors |
| Slugs | Scatter Epsom salt outdoors | Dehydrates pests |
| Odor issues | Baking soda wipe-down | Erases attractant smells |
Safety Tips and Best Practices
Natural doesn’t mean careless. Here’s how to use these ingredients safely and effectively:
| Tip | Why It Matters |
|---|---|
| Keep mixtures dry | Moisture reduces effectiveness |
| Avoid overuse in soil | Too much salt can affect plant roots |
| Reapply weekly | Natural treatments need consistency |
| Store in airtight containers | Prevent clumping and contamination |
| Keep away from pets’ bowls | Especially when used indoors |
The Bigger Picture: Why Natural Pest Control Matters
Using natural alternatives isn’t just about convenience — it’s about responsibility. Every time we choose a chemical spray, we introduce substances that may linger in the air and seep into soil or waterways.
By switching to Epsom salt and baking soda, you’re not just protecting your home — you’re helping the environment and reducing unnecessary exposure for your family.
And perhaps the most satisfying part? You’ll see results without that sharp, synthetic odor that screams “pesticide.” Just a clean, fresh space that feels as safe as it looks.

Final Thought
Pests may be persistent, but nature gives us clever tools to fight back. Epsom salt and baking soda prove that the simplest ingredients can often deliver the most powerful results — safely, affordably, and sustainably.
So before you reach for another can of chemical spray, try what’s already in your home. A sprinkle here, a wipe there, and within days, you’ll notice the difference — fewer pests, fresher air, and peace of mind knowing your home is truly clean.
Sometimes the best solutions don’t come from the store — they come from your own kitchen shelf.
