Every year, American households spend billions on pest control products, from sprays to traps and poisons. According to the U.S. Environmental Protection Agency (EPA), chemical pesticides can pose risks not only to pests but also to children, pets, and the environment. But what if a simple, everyday item sitting in your bathroom could help deter unwanted intruders? Surprisingly, some homeowners claim that toothpaste—especially mint-flavored varieties—can keep ants, cockroaches, and even mice away.
This idea might sound unconventional, but it’s gaining attention among people seeking affordable, low-toxicity solutions. While toothpaste is not a replacement for professional pest control, it may serve as a quick, practical trick to discourage pests in certain areas of your home. In this article, we’ll break down why toothpaste might work, how to apply it safely, and when it’s best to call an expert.
Why Toothpaste Might Deter Pests
Toothpaste is not designed as a pest repellent, but some of its ingredients mimic natural deterrents used in DIY pest control. Here’s why it could have an effect:
- Mint oil and menthol: Ants, mice, and roaches dislike strong scents like peppermint or menthol, which can overwhelm their sensitive smell receptors.
- Strong aroma: Toothpaste’s chemical scent may mask food odors and disrupt insect scent trails.
- Sticky texture: Applied as a barrier, it can slow crawling insects or discourage them from crossing treated areas.
While there’s little formal research on toothpaste for pest control, the logic is similar to why peppermint oil sprays and other strong-smelling household items sometimes work as deterrents.
How to Use Toothpaste for Common Household Pests
For Ants
Ants rely on scent trails to find food. Breaking these trails can discourage them from returning.
How to apply:
- Identify entry points (windowsills, baseboards, cracks).
- Apply a thin line of mint toothpaste along these access areas.
- Reapply every day or after cleaning.
Extra tip: Mix toothpaste with baking soda and place small dabs on paper near ant trails.
For Cockroaches
Cockroaches are notoriously resilient, but they dislike strong minty smells.
Try this method:
- Mix toothpaste with a pinch of sugar and flour.
- Place the mixture on small pieces of cardboard and set them under sinks, stoves, or dark corners.
- The sugar lures them, while the toothpaste scent makes the area less attractive.
Note: This won’t eliminate roaches but may help discourage them while you work on deeper solutions.
For Mice
Mice use scent cues to navigate. Strong mint smells can disrupt their patterns.
How to use:
- Spread mint toothpaste along suspected entry points (cupboards, pantry edges, baseboards).
- Refresh every 2–3 days.
- Combine with steel wool or proper sealing for long-term prevention.
Safety Tips for Using Toothpaste Around the House
Toothpaste is generally safe, but some precautions are important:
- Pet safety: Avoid areas pets can lick, especially if the toothpaste contains xylitol, which is toxic to dogs.
- Food safety: Never apply toothpaste on food prep surfaces.
- Child safety: Keep away from small children who might be curious about its sweet scent.
- Moderation: Use toothpaste as a temporary measure, not your only pest strategy.
Other Natural Pest Control Alternatives
Toothpaste may help in mild cases, but pairing it with other natural methods improves results.
| Natural Option | How It Helps | Best Use |
|---|---|---|
| Peppermint oil spray | Strong scent repels ants, roaches, mice | Mix 10 drops with water, spray doorways |
| Vinegar solution | Breaks ant trails, disinfects | Clean counters with 50/50 mix |
| Bay leaves/cloves | Repel pantry pests | Place in jars, corners, or cupboards |
| Cucumber peels | Ant deterrent | Leave fresh peels near entry spots |
These remedies are cost-effective, safe, and can be combined with good home hygiene for better results.
When to Call a Professional
DIY methods like toothpaste work best for small problems, but larger infestations often require expert help. Contact a licensed exterminator if you:
- See pests during the day (a sign of infestation).
- Notice droppings, gnawed wires, or food packaging damage.
- Hear scratching or scurrying in walls.
- Have recurring issues despite cleaning and sealing entry points.
A professional can identify root causes—like hidden nests, water leaks, or structural gaps—and apply safe, targeted treatments.
Conclusion

Does toothpaste really repel pests?
It may deter ants, roaches, and mice in small areas, thanks to its mint scent and sticky texture, but it’s not a long-term fix.
Is it safe to use around kids and pets?
Generally yes, but avoid xylitol-based toothpaste near dogs and keep applications away from food surfaces.
Can toothpaste replace pest control products?
